Terms of Service

Effective September 29, 2026 · Last updated September 29, 2026

These terms are an agreement between you and XT4 Enterprises LLC ("dmarcful", "we", "us") covering your use of dmarcful.com, its free tools and its paid DMARC Reports service (together, the "Service"). If you use the Service on behalf of an organization, you agree to these terms for that organization and confirm you have authority to do so. If you don't agree, don't use the Service.

1. The Service

• Free tools: DNS and email diagnostics (such as SPF, DMARC, DKIM, MX, blocklist, SMTP and deliverability checks), available without an account.
• DMARC Reports: a paid subscription that collects the DMARC aggregate reports sent for your domains and analyzes them in a dashboard.

We may change, add or remove features. If we remove a material paid feature, we will give reasonable notice.

2. Accounts

You must provide accurate information, keep your sign-in credentials secure, and tell us promptly about any unauthorized use. You are responsible for activity under your account. You must be at least 16 years old to create an account.

3. Free trial, subscriptions and billing

• Free trial: each plan starts with a 30-day free trial. A payment card is required to start it. One free trial per customer: if a card has already been used for a dmarcful trial, a new subscription with that card starts as paid immediately.
• Automatic renewal: unless you cancel before the trial ends, your card is charged the plan price when the trial ends and then every month until you cancel. Prices are shown before checkout and exclude taxes unless stated.
• Cancellation: you can cancel at any time from Plan & billing. Cancellation takes effect at the end of the current billing period, and you keep access until then.
• Refunds: fees are non-refundable, including for partial months, except where the law requires otherwise.
• Plan changes: upgrades and downgrades take effect through the billing portal and are prorated as shown there. Each plan includes a number of domains; domains beyond your plan's limit stay stored but can't be viewed until you upgrade or remove others.
• Failed payments: if a payment fails, we and Stripe will retry. If payment still can't be collected, your access is suspended.
• Price changes: we will give at least 30 days' notice of a price increase, which applies from your next billing period.

4. Your domains and data

• You may only add domains that you own or are authorized to monitor, and only direct reports to dmarcful for those domains.
• You keep all rights to your data. You give us permission to store and process it only as needed to provide, secure and support the Service.
• After your subscription ends, your report address keeps collecting reports for 90 days so you can resubscribe without losing history. After 90 days without an active subscription, your report data is deleted permanently. Our Privacy Policy explains how we handle personal data.

5. Acceptable use

You agree not to:

• use the Service to attack, probe or disrupt systems you are not authorized to test, or to send spam;
• use automated means to query the free tools at a volume that bypasses or strains our rate limits;
• interfere with, disrupt or gain unauthorized access to the Service or its infrastructure;
• resell or offer the Service to third parties without our written agreement;
• use the Service in violation of any law.

We may suspend or limit access that we reasonably believe violates these rules.

6. Third-party services

The Service relies on third parties, including Clerk (sign-in), Stripe (payments), Twilio SendGrid (email intake) and public DNS and blocklist providers. Your use of those services may also be subject to their terms. We are not responsible for their availability or accuracy.

7. Results and recommendations

Diagnostics and recommendations are based on DNS data, reports from mailbox providers and other third-party data, which can be incomplete, delayed or wrong. They are provided for information. Changes to your DNS and DMARC policy are your decision and responsibility. In particular, a stricter DMARC policy (quarantine or reject) can cause legitimate email to be filtered or rejected. We do not guarantee email deliverability.

8. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE". TO THE EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT, AND WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED OR ERROR-FREE.

9. Limitation of liability

TO THE EXTENT PERMITTED BY LAW, NEITHER PARTY WILL BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, DATA OR GOODWILL. OUR TOTAL LIABILITY FOR ANY CLAIM RELATING TO THE SERVICE IS LIMITED TO THE AMOUNT YOU PAID US FOR THE SERVICE IN THE 12 MONTHS BEFORE THE CLAIM AROSE, OR US $100 IF YOU HAVE NOT PAID US ANYTHING.

10. Indemnity

You will defend and indemnify us against third-party claims arising from your violation of these terms or your use of the Service for domains you are not authorized to monitor.

11. Termination

You may stop using the Service and delete your account at any time. We may suspend or terminate your access if you materially breach these terms, or with 30 days' notice for any other reason, in which case we will refund any prepaid fees for the unused period. Sections 4 (data deletion), 7–10 and 12 survive termination.

12. Governing law and disputes

These terms are governed by the laws of the State of Wyoming, United States, without regard to conflict-of-laws rules. Disputes will be resolved in the state or federal courts located in the State of Wyoming, and both parties consent to their personal jurisdiction and venue. To the extent permitted by law, you and we each waive any right to a jury trial and agree that claims may be brought only on an individual basis, not as a plaintiff or class member in any class, consolidated or representative proceeding.

13. Changes to these terms

We may update these terms. We will post changes here and, for material changes, notify account holders by email at least 30 days before they take effect. Continuing to use the Service after that means you accept the updated terms.
