Terms of Use

Last updated: 8 July 2026

1. Who we are

RDA Deliverability is an independently operated online specialist service business focused on email authentication, domain trust and related technical assurance.

RDA Deliverability is currently operated as a sole proprietorship. A company registration number does not apply unless and until the business is incorporated or otherwise registered in a form that requires one.

Additional operator identity and formal service details may be provided in a separate legal disclosure on the website and in formal contracting documents where required.

RDA provides services remotely and may work with business clients in different countries.

You can contact us at:

RDA Deliverability
Telephone: +27 76 3111 590
Email: info@rdadeliverability.com
Website: rdadeliverability.com

In these Terms, references to RDA, we, us or our mean RDA Deliverability and its operator.

References to you, your or client mean the person or organisation using the website, submitting an enquiry or engaging RDA for services.

2. Our services

RDA specialises in assessing, strengthening and reviewing the technical trust environment behind business email.

Our principal services are:

• Email Trust Health Check — a professional assessment of the email authentication and domain trust environment behind an agreed business domain;
• Remediation & Strengthening — separately scoped correction of justified authentication, alignment, authorised sending-source and relevant email-related DNS issues; and
• Trust Monitor — ongoing review of authentication, policy, sending-source changes and meaningful trust-layer drift after a suitable baseline has been established.

RDA may also provide related investigation, verification, advisory, assurance, coordination or technical support where specifically agreed in writing.

Our website and services are intended primarily for business and professional use. A person accepting a proposal, paying an invoice, completing onboarding or giving instructions on behalf of an organisation confirms that they are authorised to do so.

RDA does not market its specialist services for personal, family or household use. If we expressly agree to serve an individual outside a business context, any mandatory rights that apply to that transaction remain unaffected.

3. Specific service scopes take priority

A specific engagement may also be governed by a proposal, quotation, statement of work, invoice, order confirmation or other written scope agreed with you.

If there is a direct conflict between documents, the following order of priority applies unless expressly agreed otherwise:

1. an expressly accepted proposal, statement of work or service agreement;
2. the specific scope, price and payment terms confirmed in an invoice or written order confirmation;
3. these Terms; and
4. general information elsewhere on the website.

Website descriptions are general. The actual work RDA is required to perform is the scope specifically agreed for the engagement.

4. Website use

You may use this website only for lawful purposes.

You must not:

• damage, disable, overload, disrupt or interfere with the website or its availability;
• attempt to gain unauthorised access to the website, forms, servers, systems, accounts or data;
• introduce malware, malicious code or other harmful material;
• impersonate another person or organisation;
• submit information that you know to be false, fraudulent or materially misleading;
• conduct security testing, vulnerability scanning or penetration testing against our systems without written authorisation;
• use automated systems in a way that interferes with the website or infringes our rights; or
• use the website for any unlawful purpose.

We may restrict access where reasonably necessary to protect our website, systems, users or business.

5. Information on this website

Website content is provided for general business, educational and service-information purposes.

A public DNS record, authentication result, automated scan or other public signal is not, by itself, a complete diagnosis of an email environment.

We aim to keep website information accurate and useful, but we do not guarantee that every page, technical statement, price or service description will always be complete, current or suitable for every environment.

Prices and service descriptions may change before an engagement is accepted. Once a specific engagement has been confirmed, the price and scope agreed for that engagement will apply.

6. When a service relationship begins

Submitting a contact form, sending an email, requesting information or having an initial discussion does not by itself create a client relationship or require RDA to accept work.

A service relationship begins when RDA confirms acceptance of the engagement and the requirements for commencement have been met.

Depending on the service, those requirements may include:

• acceptance of a proposal or scope;
• payment of an invoice or required initial amount;
• completion of onboarding;
• receipt of required information or evidence; or
• written confirmation that work may begin.

RDA may decline work that falls outside our scope, involves risks we are not equipped to accept, lacks required cooperation or authority, or would be unlawful, unsafe or professionally inappropriate.

7. Email Trust Health Check

The Email Trust Health Check is a standalone professional assessment.

It is not a deposit toward remediation and is not automatically credited against future remediation or other services.

Depending on the agreed scope and available evidence, the Health Check may include:

• the primary business domain and relevant email-related DNS;
• SPF existence, structure, sender authorisation and technical health;
• observed or client-confirmed DKIM deployment;
• DMARC validity, alignment, reporting and policy position;
• known legitimate sending systems and relevant sending subdomains;
• authentication alignment;
• confirmed findings;
• evidence gaps and unresolved unknowns; and
• a prioritised roadmap where further action is justified.

The assessment may conclude that:

• the assessed environment appears healthy within the evidence available;
• a limited corrective action should be considered;
• further verification is required before a reliable conclusion can be reached; or
• a separately scoped remediation project is justified.

Unknown or unavailable evidence will not automatically be treated as a failure. Where a condition cannot be confirmed, RDA may identify it as requiring verification.

Delivery estimates begin only after the information and evidence reasonably required for the assessment have been received.

Complex, multi-domain, incident-related or unusually large environments may require a different scope and price.

8. Remediation & Strengthening

Remediation is separate from the Email Trust Health Check.

It is undertaken only after the relevant environment, dependencies, risks and proposed implementation route are sufficiently understood.

Remediation may include agreed work relating to:

• SPF structure and sender authorisation;
• DKIM deployment or correction;
• DMARC implementation, correction or evidence-led policy progression;
• authentication alignment;
• legitimate sending sources;
• relevant email-related DNS;
• sending subdomains; and
• post-change verification and documentation.

The implementation route depends on the environment and the risk of the proposed change.

RDA may:

• implement an approved change directly;
• guide or coordinate the client’s internal IT team;
• coordinate with the client’s existing technology provider; or
• use appropriately skilled specialist support where complexity requires it.

RDA will not intentionally implement a material technical change unless the agreed route allows us to explain and verify the change, understand its likely impact and establish a reasonable rollback position where rollback is technically possible.

A remediation recommendation does not oblige you to purchase remediation from RDA.

9. Trust Monitor

Trust Monitor is an ongoing review and assurance service for suitable environments where a baseline has first been established.

Depending on the agreed scope, Trust Monitor may include:

• review of SPF, DKIM, DMARC, alignment and policy position;
• review of newly observed or unexpected sending sources;
• identification of meaningful change or drift;
• investigation of relevant authentication failures or changes;
• review of readiness for policy progression where appropriate; and
• periodic assurance summaries and recommendations.

10. Work outside the standard scope

Unless expressly included in writing, standard RDA services do not include:

• active cyber incident response;
• digital forensics;
• malware investigation;
• mailbox compromise investigation;
• business email compromise recovery;
• legal or regulatory investigations;
• penetration testing;
• full network or cloud security audits;
• large-scale email migrations;
• hybrid or on-premises Exchange remediation;
• major MX or mail-routing changes;
• general IT support;
• 24-hour emergency support; or
• work unrelated to the agreed email authentication and domain trust scope.

If RDA identifies an issue that requires work outside our scope, we may recommend separate scoping, involvement of the client’s existing provider or suitably qualified specialist support.

11. Client responsibilities

The quality and safety of our work depend on accurate information and appropriate cooperation.

You are responsible for:

• providing accurate and complete information to the best of your knowledge;
• identifying known legitimate sending systems and relevant subdomains;
• providing requested evidence within a reasonable time;
• telling RDA about material changes that may affect the work;
• ensuring that people giving instructions are authorised to do so;
• obtaining internal approval for proposed changes;
• maintaining appropriate control of your domains, DNS, email systems and accounts;
• maintaining appropriate backups, exports and recovery arrangements for systems under your control;
• complying with the terms of third-party platforms you use; and
• making final business, legal, compliance and risk decisions for your organisation.

RDA is not responsible for an incorrect conclusion or unsuccessful implementation to the extent that it results from materially inaccurate, incomplete, withheld or outdated information supplied to us.

12. Authority to request work

You confirm that you have the authority to ask RDA to assess, access, review, configure or coordinate work involving any domain, DNS zone, platform, account, system or data included in the engagement.

You must not instruct RDA to access or change systems you do not own or have authority to administer.

Where another organisation, technology provider, administrator or domain owner must approve work, you are responsible for obtaining the required authority unless RDA expressly agrees to coordinate that process.

13. Access, credentials and security

The Email Trust Health Check normally begins with public information, onboarding answers and specific evidence requested by RDA.

Where later work genuinely requires system access:

• RDA will request only the access reasonably needed for the agreed work;
• delegated, role-based or temporary access should be used where practical;
• access should be provided through an agreed method;
• you remain responsible for deciding whether access should be granted; and
• you should remove, rotate or revoke access when it is no longer required.

You remain responsible for your internal access-control, account-security and credential-management practices.

14. Change approval and implementation

RDA will not intentionally make a material change to a client-controlled production environment without an agreed approval route.

Approval may be provided through:

• an accepted remediation proposal;
• a written implementation plan;
• email approval from an authorised representative;
• an agreed ticketing or change-management process; or
• another recorded method agreed for the engagement.

Technical environments vary. A rollback may not always be immediate or capable of reversing every external effect of a change.

DNS propagation, caching, third-party processing and external provider behaviour may continue after a record or configuration has been changed.

Where practical, RDA will identify relevant dependencies and a reasonable rollback position before higher-risk work begins.

15. Client IT providers and specialist support

RDA may work with your internal IT team, managed service provider, hosting provider, DNS provider, email administrator or another authorised technical representative.

RDA may also use trusted specialist support where the complexity or risk of the work reasonably requires expertise beyond our standard delivery route.

Where specialist support may access confidential or personal information, RDA will take reasonable steps to limit access to what is necessary for the agreed work.

Unless agreed otherwise, RDA remains the primary point of coordination for specialist support engaged by RDA.

Material specialist costs will be included in the agreed scope or separately approved before they are incurred.

RDA is not responsible for the independent acts or omissions of a third party selected, instructed or controlled directly by the client and outside RDA’s agreed scope.

16. Timing and delivery estimates

Delivery times stated on the website, in proposals or in correspondence are good-faith estimates unless expressly confirmed as guaranteed in writing.

Timing may depend on:

• receipt of onboarding information and requested evidence;
• client response times;
• availability of required access;
• third-party provider response times;
• DNS propagation and caching;
• the complexity of the environment;
• the need for staged observation or policy progression; and
• events outside RDA’s reasonable control.

RDA will communicate material delays where reasonably practicable.

17. Pricing and payment

The price applicable to an engagement is the price stated in the accepted proposal, quotation, invoice or written order confirmation.

Unless another currency is expressly stated, prices quoted to international clients may be stated and payable in United States dollars (USD).

Unless otherwise agreed in writing:

• the Email Trust Health Check must be paid in full before assessment work begins;
• remediation payment terms will be stated in the relevant proposal or invoice;
• ongoing services are billed according to the confirmed recurring arrangement; and
• amounts are due by the date stated on the invoice.

The Health Check fee is separate from remediation and is not automatically deducted from or credited against a later remediation project.

Unless expressly stated otherwise, prices shown on the website may change before an engagement is accepted.

Currency, applicable taxes and any other agreed charges will be shown on the relevant invoice.

RDA may accept payment by bank transfer, online payment link or another method stated on the invoice. You are responsible for any bank, intermediary or currency-conversion charges imposed by your own financial institution or payment provider.

You must not initiate a payment reversal or chargeback in bad faith or use a chargeback as a substitute for raising a genuine service dispute with RDA. Nothing in this paragraph removes any payment-dispute right that cannot lawfully be waived.

RDA may pause work where a material payment obligation is overdue, provided that pausing the work would not create an unreasonable technical or security risk.

18. Cancellations, cooling-off rights and refunds

Nothing in these Terms removes any cancellation, cooling-off, refund or other right that applicable law does not permit the parties to exclude.

Email Trust Health Check

If you cancel before RDA begins substantive assessment work, RDA will refund amounts paid for the Health Check, less any non-refundable third-party cost that you expressly approved and that has already been incurred.

Substantive assessment work may include:

• review of onboarding information;
• evidence collection;
• sending-source mapping;
• DNS and authentication investigation;
• technical analysis; or
• preparation of findings.

Once substantive work has begun, RDA may retain the reasonable value of work properly performed and approved costs already committed. Any remaining unearned balance will be dealt with fairly in light of the stage reached, the agreed fixed-fee scope and applicable law.

This does not limit any right you may have where RDA materially fails to provide the agreed service.

Statutory cooling-off rights

Where a statutory cooling-off right applies to an electronic transaction, that right will be respected.

Where you expressly ask RDA to begin services before an applicable statutory cooling-off period has ended, you request early performance of the service. Any legal exception or consequence that validly follows from that request will apply, but no right that cannot lawfully be waived is removed.

Remediation projects

Cancellation terms for remediation depend on the agreed scope and the stage of work reached.

If a remediation project is cancelled, you remain responsible, subject to applicable law, for:

• work properly completed up to the effective cancellation date;
• approved work already committed where it cannot reasonably be avoided; and
• approved third-party costs that cannot reasonably be recovered.

If amounts paid in advance exceed the amount properly due after the cancellation calculation, RDA will refund the balance.

Trust Monitor and recurring services

Cancellation terms for recurring services will be stated in the applicable proposal, invoice or service confirmation.

If no different notice period is stated, a month-to-month ongoing service may be cancelled on 30 calendar days’ written notice.

Amounts properly due up to the effective cancellation date remain payable.

19. Changes to scope

If requested work materially changes, expands or becomes more complex after commencement, RDA may pause the affected work and provide a revised scope, price or delivery estimate before continuing.

RDA is not required to perform material work that falls outside the agreed scope without further agreement.

20. Confidentiality

Each party may receive confidential business, technical or commercial information from the other.

Each party agrees to:

• use confidential information only for the relevant engagement or another authorised purpose;
• take reasonable steps to protect it from unauthorised disclosure;
• limit access to people who reasonably need the information for the agreed purpose; and
• not disclose it to third parties except as permitted by these Terms, the agreed scope or applicable law.

Confidential information does not include information that:

• is already lawfully public through no breach of confidence;
• was lawfully known to the receiving party before disclosure;
• is independently developed without use of the confidential information; or
• is lawfully received from another person without a duty of confidence.

A party may disclose information where legally required, subject to any lawful restrictions on notification.

21. Privacy and personal information

Our handling of personal information is described in our Privacy Policy.

Depending on the service, RDA may receive business contact details, domain information, sending-system information, screenshots, technical records, configuration evidence and other information reasonably necessary to perform the agreed work.

You are responsible for avoiding unnecessary disclosure of confidential, sensitive or personal information.

Where you provide personal information about another person, such as an employee, IT contact or provider representative, you confirm that you are authorised or otherwise lawfully entitled to provide that information for the relevant business purpose.

22. Third-party platforms and providers

RDA’s work may involve or depend on third-party providers, including:

• domain registrars;
• DNS providers;
• email providers;
• cloud platforms;
• CRM and business applications;
• website and form platforms;
• monitoring or reporting tools; and
• client-appointed technology providers.

Third-party services are outside RDA’s direct control.

To the extent permitted by law, RDA is not responsible for an outage, delay, pricing change, product change, policy change, account suspension, service discontinuation or provider-side failure caused solely by an independent third-party provider.

A recommendation to use or retain a third-party platform is not a guarantee of that provider’s future performance, security, pricing or availability.

23. Reports, findings and deliverables

Findings are based on the agreed scope and the information and evidence reasonably available at the time of assessment or review.

Email environments change.

A finding that is accurate at the time of review may later change because of:

• new platforms;
• DNS changes;
• new sending sources;
• provider changes;
• configuration drift; or
• other changes outside RDA’s control.

RDA may distinguish between:

• confirmed findings;
• issues requiring verification;
• evidence gaps;
• conditions to monitor; and
• matters outside the agreed scope.

You should review deliverables and notify RDA of any material factual error you identify within a reasonable time.

24. Intellectual property

RDA retains ownership of its pre-existing and general:

• methods;
• processes;
• templates;
• frameworks;
• checklists;
• tools;
• software;
• document structures;
• know-how; and
• website content.

Once the applicable fees have been paid, you may use client-specific reports, findings, implementation documentation and other paid deliverables for your own internal business purposes.

You may share relevant deliverables with your employees, professional advisers, insurers and authorised technology providers where reasonably necessary for your business.

You may not, without written permission:

• resell RDA deliverables;
• present them as work created by another provider;
• commercially reproduce RDA templates or methodology;
• remove ownership notices and redistribute materials as a competing product; or
• copy substantial website content for commercial use.

25. Client names, logos and case studies

RDA will not publish your name, logo, testimonial, identifiable results or identifiable case study for marketing purposes without permission.

26. No guarantee of inbox placement or business results

Email outcomes may be influenced by factors including:

• mail-provider systems and policies;
• sender and domain reputation;
• sending behaviour and volume;
• message content;
• recipient engagement;
• list quality;
• spam and abuse filtering;
• third-party platform behaviour;
• historical activity; and
• changes made outside RDA’s control.

SPF, DKIM and DMARC are important components of email authentication, but they do not prevent every form of impersonation, account compromise, social engineering, fraud or malicious activity.

27. No legal, financial or regulatory advice

RDA provides technical and business advisory services relating to email authentication and domain trust.

Unless expressly agreed in writing with an appropriately qualified professional, RDA does not provide:

• legal advice;
• financial advice;
• tax advice;
• insurance advice;
• formal regulatory advice; or
• certification of legal or regulatory compliance.

You should obtain independent professional advice where a decision requires legal, regulatory, financial or other specialist expertise.

28. Service standard and warranties

RDA will aim to perform agreed services with reasonable care and skill appropriate to the agreed scope.

Except for rights and warranties that cannot lawfully be excluded, RDA does not warrant that:

• the website will always be uninterrupted or error-free;
• every technical weakness or unauthorised sending source will be identified;
• every recommendation will produce a particular external outcome;
• third-party platforms will continue to behave as expected; or
• an email environment will remain unchanged after an assessment or remediation.

Nothing in these Terms excludes a warranty, duty or right that applicable law does not permit RDA to exclude.

29. Limitation of liability

To the maximum extent permitted by law, RDA will not be liable for indirect, special, incidental, punitive or consequential loss arising from the website or a service engagement.

This may include indirect loss of:

• profit or revenue;
• business opportunity;
• anticipated savings;
• goodwill or reputation;
• leads or sales;
• email engagement;
• data; or
• business continuity.

To the maximum extent permitted by law, RDA’s total aggregate liability arising from a specific one-time engagement will not exceed the fees paid to RDA for that engagement.

For an ongoing service, RDA’s total aggregate liability arising from that service will not exceed the fees paid for the affected service during the six months immediately preceding the event giving rise to the claim.

These limitations do not apply to liability arising from:

• fraud;
• wilful misconduct;
• gross negligence to the extent it cannot lawfully be excluded;
• death or personal injury where liability cannot lawfully be limited; or
• another liability that applicable law does not permit RDA to exclude or limit.

Each party must take reasonable steps to reduce avoidable loss arising from an incident or dispute.

30. Unlawful or unauthorised instructions

You are responsible for the instructions, access and materials that you provide to RDA.

To the extent permitted by law, you are responsible for loss or third-party claims arising directly from:

• your deliberate provision of false authority to access a system;
• your instruction that RDA perform unlawful activity;
• material supplied by you that infringes another person’s rights; or
• your material breach of these Terms.

This section does not make you responsible for loss caused by RDA’s own fraud, wilful misconduct, gross negligence or another liability that cannot lawfully be excluded.

31. Suspension and termination

RDA may suspend affected work where reasonably necessary because:

• required payment is materially overdue;
• necessary information, evidence, access or approval has not been provided;
• continuing would create an unreasonable technical or security risk;
• instructions appear unauthorised or unlawful;
• the scope has materially changed and requires further agreement;
• there is abusive, threatening or seriously inappropriate conduct; or
• another serious breach of the service arrangement has occurred.

Where reasonably practical, RDA will explain the reason and provide an opportunity to resolve the issue before termination.

Either party may terminate an engagement for a material breach that is not remedied within a reasonable time after written notice, where the breach is capable of remedy.

RDA may terminate immediately where continuation would be unlawful, unsafe, fraudulent or likely to cause serious harm.

Termination does not remove payment obligations for work properly completed or committed up to the effective termination date.

32. Events outside reasonable control

Neither party will be treated as having breached an obligation because of delay or failure caused by an event genuinely outside its reasonable control, provided the affected party takes reasonable steps to reduce the effect of the event.

Such events may include:

• widespread internet or telecommunications failure;
• major cloud or provider outages;
• government action;
• natural disaster;
• war, civil disorder or terrorism;
• labour disruption;
• serious cyber incidents affecting unrelated infrastructure; or
• another comparable event outside reasonable control.

Payment obligations for work already completed are not cancelled by this section.

33. Electronic communications and acceptance

You agree that RDA may communicate with you electronically, including through email, website forms, digital invoices and other agreed business communication channels.

To the extent permitted by law, a proposal, instruction, approval or acceptance may be evidenced electronically.

Paying an invoice, accepting a proposal electronically, completing onboarding or providing written instructions for work to begin may constitute acceptance of the relevant service arrangement.

You are responsible for keeping your contact information current and for ensuring that authorised representatives use appropriate business accounts when giving important instructions.

34. Governing law and disputes

These Terms and any non-contractual dispute arising from them are governed by the laws of the Republic of South Africa, subject to any mandatory law that applies and cannot lawfully be excluded.

If a dispute arises, the parties should first attempt in good faith to resolve it through direct written discussion.

Either party may propose mediation or another appropriate dispute-resolution process.

If the dispute cannot be resolved, either party may refer the matter to a court with competent jurisdiction.

Nothing in this section prevents a party from seeking urgent legal relief where reasonably necessary.

35. Non-waivable legal rights

Nothing in these Terms is intended to:

• remove a right that cannot lawfully be waived;
• exclude an obligation that applicable law requires RDA to perform;
• limit liability where the law does not permit limitation; or
• replace mandatory consumer protection that applies to a particular transaction.

Where applicable law provides greater protection than these Terms, that mandatory protection will prevail to the extent of the conflict.

36. Severability

If any provision of these Terms is found to be unlawful, invalid or unenforceable, that provision will be limited or removed only to the extent necessary.

The remaining provisions will continue to apply.

37. No waiver

A delay or failure by either party to enforce a right does not automatically waive that right.

A waiver applies only to the specific matter for which it is given.

38. Transfer of an engagement

You may not transfer an active service engagement to another person or organisation without RDA’s written agreement.

RDA may transfer its rights and obligations as part of a genuine sale, restructuring or transfer of the business, subject to applicable law and appropriate protection of confidential and personal information.

39. Entire agreement

The agreed proposal, scope, quotation, invoice or order confirmation, together with these Terms and any document expressly incorporated into them, form the agreement for the relevant service.

Nothing in this section excludes liability for fraud, fraudulent misrepresentation or another matter that cannot lawfully be excluded.

40. Changes to these Terms

RDA may update these Terms to reflect changes to our services, business practices, technology or legal requirements.

The latest website version will show the date of the most recent update.

Changes apply to website use from the date they are published.

Material changes affecting an active engagement will not retroactively replace an expressly agreed service term unless the parties agree or applicable law requires the change.

41. Contact and legal notices

Questions about these Terms or an engagement may be sent to:

RDA Deliverability
Email: info@rdadeliverability.com
Telephone: +27 76 3111 590

Contractual notices may be sent by email to the address above, unless the relevant proposal, invoice or service agreement provides another notice method.

A notice is not treated as received merely because it was sent. The sender should retain reasonable evidence of transmission and, for important notices, request acknowledgement.

Service of court process or another document that applicable law requires to be served in a particular manner must follow that law.

These Terms should be read together with the RDA Deliverability Privacy Policy and the specific written scope for any paid engagement.
