Terms & conditions

Last updated: 28 June 2026

1. About these terms

These terms ("Terms") are a legal agreement between you (and, if you use DMARCER on behalf of an organisation, that organisation, "you", "your") and iVibe Media Limited, trading as DMARCER (company number 17212558, registered office 2 Frederick Street, Kings Cross, London, United Kingdom, WC1X 0ND) ("DMARCER", "we", "us"). By creating an account, using the platform, or using our free tools, you agree to these Terms. If you are agreeing on behalf of an organisation, you confirm you have authority to bind it.

2. The service

DMARCER is an email-security platform that monitors, scores and helps remediate a domain's email-authentication posture (SPF, DKIM, DMARC, MTA-STS, TLS-RPT and DNSSEC), including DMARC report processing, hosted records, DNS remediation tooling, alerting and benchmarking. Features available to you depend on your plan. We may improve, change or discontinue features over time.

Beta and early-access features. We may make features available that are labelled beta, preview, early-access or "coming soon". These are provided "as is", may be incomplete or less reliable, may be changed or withdrawn at any time, and are excluded from any availability, support or service-level commitments.

3. Accounts and eligibility

You must provide accurate registration details and keep your credentials secure; you are responsible for activity under your account. DMARCER is intended for business use and you must be at least 18. We may enrol multi-factor authentication and may suspend accounts to protect the platform.

4. MSP and multi-tenant use

If you use DMARCER to manage domains for your own clients (for example as a managed service provider), you are responsible for those clients' use, for having the necessary authority and lawful basis to manage their domains and data, and for your own agreements with them. You will not exceed the tenant or seat entitlements of your plan.

5. Your responsibilities and authorisation

You warrant that you own, or are authorised to manage, every domain and DNS zone you add to DMARCER, and that you may submit the associated data to us. You are responsible for reviewing recommendations before applying them. Where you use DNS remediation, hosted SPF/MTA-STS/DKIM or similar features, you authorise us (or our tooling) to make the changes you approve; such changes can affect mail delivery, and you are responsible for testing and for the configuration you choose. Many changes can be previewed and reverted, but you remain responsible for your DNS.

6. Free tools, benchmark and AI assistant

Our free domain check, generators, benchmark and AI-assistant (MCP) connector are provided "as is", for lawful use, and may be rate-limited or withdrawn. You may use the free tools only on domains you own or are authorised to assess, and you must not use them to attack, overload, scrape or disrupt any system or third party.

7. Acceptable use

You must not: use DMARCER to break the law or infringe rights; probe, scan or test domains you are not authorised to assess; attempt to gain unauthorised access; interfere with or overload the platform; resell or expose the service except as permitted by your plan; misuse forensic data; copy, modify or create derivative works of the platform; reverse-engineer, decompile or disassemble it except to the extent that restriction cannot be excluded by law; or use it to build, train or benchmark a competing product or service. We may suspend or terminate access for breach.

8. Subscriptions, billing and renewals

When you subscribe to a paid plan you commit to a subscription term, either monthly or annual. Annual plans are offered at a discounted rate in return for the longer commitment. Plans are billed in advance for the chosen term via our payment provider, Stripe. Fees are exclusive of VAT and other applicable taxes, which are added where required. All amounts are payable in full without deduction, set-off or counterclaim.

Automatic renewal. Your subscription renews automatically for a further term of the same length unless you cancel before the renewal date. You can cancel renewal at any time from your account or by contacting us; cancellation takes effect at the end of your current term and you keep access until then.

Renewal pricing. Renewals are charged at the plan's advertised rate at the time of renewal. We review our pricing from time to time, so the rate at renewal may differ from the rate when you first subscribed or from what you are paying in your current term. Any change applies only from your next term, never mid-term, and we will notify you of price changes by email no less than 30 days before an annual renewal, and no less than 14 days before a monthly renewal, so you can decide whether to let your subscription renew or to cancel.

Upgrades. If you upgrade your plan mid-term, the upgrade takes effect immediately. We may, at our sole discretion, apply a credit or partial refund for the unused portion of your current term towards the upgraded plan; any such credit or refund is not guaranteed.

Downgrades. If you downgrade your plan, the change takes effect at your next renewal (the end of your current subscription term); you keep your current plan and its features until then, and no refund is given for the current term.

Refunds. Other than any upgrade credit we may choose to apply at our discretion, and except where a refund is required by law, fees are non-refundable.

Free trials. Where we offer a free trial, it runs for the period stated at sign-up and, unless you start a paid subscription before it ends, will expire or convert to a free or limited tier. Trials are provided "as is" with no warranty, and we may change, limit or withdraw a trial at any time.

9. Data protection

Our handling of personal data is described in our Privacy Policy. Where we process personal data on your behalf, our Data Processing Agreement applies and forms part of these Terms. You are responsible for having a lawful basis for the data you submit, including any forensic (RUF) report data.

10. Intellectual property

We and our licensors own all rights in the DMARCER platform, software, content and benchmark. We grant you a non-exclusive, non-transferable right to use the service during your subscription in accordance with these Terms. You retain rights in your own data; you grant us the rights needed to provide the service and to produce aggregated, non-identifying statistics.

11. Third-party services

The service integrates with third parties (for example DNS, MX and PSA providers, payment and AI providers). Your use of those services is subject to their terms, and we are not responsible for them.

12. Availability, uptime and the nature of internet services

We use all reasonable efforts to keep DMARCER available and to work towards 100% uptime, but we do not warrant or guarantee that the service will be uninterrupted, timely, secure, error-free or bug-free, unless a separate service-level agreement (SLA) applies. Software of this kind may contain bugs or defects, and we do not warrant that all of them will be corrected.

The service is delivered over the public internet and relies on networks, DNS, hosting and other third parties outside our reasonable control. Both parties acknowledge and accept that occasional interruptions, latency, scheduled or emergency maintenance, and periods of downtime are an expected and normal part of delivering a service over the internet, and that such interruptions are not, of themselves, a breach of these Terms. We will use reasonable efforts to limit disruption and to give notice of planned maintenance where practicable. Current service status is published on our status page.

Your records. We keep backups for our own resilience, but these are not a substitute for your own records. You are responsible for retaining your own copies of any configurations and exported reports you need.

13. Disclaimers

DMARCER helps reduce the risk of email spoofing and improves email-security posture, but no security tool can guarantee that all spoofing, phishing or delivery problems are prevented. Except as expressly stated and to the extent permitted by law, the service and free tools are provided "as is" and "as available", and we exclude all implied warranties.

14. Limitation of liability

Nothing in these Terms limits or excludes liability that cannot be limited or excluded by law (including liability for death or personal injury caused by our negligence, or for fraud or fraudulent misrepresentation).

Subject to that, and to the maximum extent permitted by law: (a) all warranties, conditions and terms implied by statute or common law are excluded; (b) we are not liable for any indirect, special or consequential loss, or for any loss of profits, revenue, business, anticipated savings, data or goodwill, whether or not foreseeable; and (c) our total aggregate liability to you for all claims arising out of or in connection with the service, the free tools or these Terms, whether in contract, tort (including negligence), breach of statutory duty, or otherwise, is limited to the total subscription fees paid by you to us for the service in the twelve (12) month period immediately before the event, or alleged breach, giving rise to the claim. Where the matter relates to the free tools, which are provided free of charge, our total aggregate liability is limited to £100.

15. Indemnity

You will indemnify us against claims, losses and costs (including reasonable legal costs) arising from your breach of these Terms, your misuse of the service, or your lack of authority over a domain, zone or data you submit. We will notify you of any such claim, give you control of its defence and settlement (provided that any settlement which admits fault or imposes an obligation on us requires our prior written consent), and provide reasonable cooperation at your expense.

16. Suspension and termination

You may stop using the service and cancel at any time. We may suspend or terminate access if you breach these Terms, fail to pay, or to protect the platform or third parties. On termination, your right to use the service ends; we will make your data available for export for a reasonable period and then delete it in line with our Privacy Policy and any DPA.

Non-payment. If a subscription is not paid when due, we may suspend your account. Subscription fees continue to accrue during any suspension until the outstanding balance is settled. While an account is suspended you will not have access to the platform, and any accounts linked to your tenancy, including client portal accounts, will also be suspended. During suspension we may reject or stop processing for the affected domains, including ingestion of DMARC aggregate (RUA), forensic (RUF) and TLS-RPT reports, MTA-STS validation, and SPF flattening lookups. Once the outstanding balance is settled, reinstating (un-suspending) the account is at our discretion.

Termination by us. In addition to the rights above, we may suspend, terminate or discontinue the service, any account, or these Terms at our sole discretion, for any reason or no reason, giving notice where reasonably practicable. To the maximum extent permitted by law, we will not be liable to you or to any third party for any suspension, termination, discontinuation or unavailability of the service. Any refund of prepaid, unused fees following a termination by us that is not due to your breach is at our discretion. This clause does not limit any liability that cannot be excluded by law (see clause 14).

17. Changes to these terms

We may update these Terms from time to time. We will post the updated version here and update the "last updated" date; material changes affecting paid customers will be notified, and continued use after changes take effect constitutes acceptance.

18. Confidentiality

Each party will protect the other's confidential information and use it only as needed to perform under these Terms.

19. Governing law and disputes

These Terms and any dispute arising from them are governed by the laws of England & Wales, and the courts of England & Wales have exclusive jurisdiction, except that we may seek injunctive relief in any appropriate jurisdiction.

20. General

You may not assign these Terms without our consent; we may assign them to a successor of our business. If any provision is found unenforceable, the rest remains in effect. Our failure to enforce a right is not a waiver. These Terms (together with the Privacy Policy, any DPA and your plan/order details) are the entire agreement between us. Neither party is liable for failure caused by events beyond its reasonable control.

Provisions that by their nature should survive termination, including those on intellectual property, confidentiality, disclaimers, limitation of liability, indemnity and governing law, survive. These Terms do not confer any rights on third parties under the Contracts (Rights of Third Parties) Act 1999. We may give notices to you by email to your account address or by posting within the service; formal notices to us should be sent to hello@dmarcer.net.
