Terms of Service

These terms govern the MarkRelay website, customer portal, purchases, license delivery, and support. The self-hosted MarkRelay application runs in the customer's Cloudflare account; it is not a hosted mailbox service operated by MarkRelay.

1. Acceptance and eligibility

By creating an account, placing an order, or using this website, you agree to these terms and the license terms presented for the product you purchase. You must be able to enter a binding contract and, when acting for an organization, have authority to bind that organization.

2. Customer account

You are responsible for accurate account information, safeguarding credentials, and activity under your account. Notify us promptly if you believe an account or order has been compromised. We may suspend website access to protect customers, investigate fraud, or enforce these terms.

3. Products and license scope

  • Annual License. The right to deploy and use the software, including generally released updates, for as long as the yearly subscription is paid. It renews automatically each year until you cancel. When it ends, the right to use the software ends, and deployments stop working after a short grace period.
  • Lifetime License. A perpetual right to deploy and use the software, including all generally released updates.
  • Source License. Everything in the Lifetime License, plus the complete source code. You may modify it, deploy it for yourself and your clients, and integrate it, original or modified, into your own products and services. You may not distribute, publish, sublicense, or sell the source code itself, original or modified.

Every license may be used for any purpose, including deployments you operate for clients or end users. Each license covers a single Cloudflare account: you may deploy it in that account any number of times, each time activated with a one-time activation code of the license, but not in another Cloudflare account, which needs its own license. Deployments check their license with us periodically, and we may revoke a license used outside these terms. You may not copy, decompile, redistribute, or resell the software, except as a Source License allows above.

The specific license agreement delivered with a product controls if it conflicts with this website summary. You may not obtain, copy, share, resell, or bypass access to software outside the rights of your purchased license.

4. Self-hosted deployment responsibilities

You are responsible for:

  • your Cloudflare account, plan, billing, account approvals, domains, DNS, Email Routing, outbound sending access, and service quotas;
  • deployment, administrator access, secrets, upgrades, backups, monitoring, retention, security, and incident response;
  • the lawfulness, accuracy, and security of mailbox and recipient data in your deployment; and
  • compliance with anti-spam, privacy, consumer-protection, export, and other laws that apply to your messages and users.

Cloudflare and recipient mail providers are independent third parties. MarkRelay does not control their availability, limits, pricing, delivery decisions, or policy enforcement and does not guarantee inbox placement.

5. Acceptable use

You may not use MarkRelay to send unlawful, deceptive, abusive, or unsolicited messages; distribute malware; impersonate others; harvest addresses; violate privacy or intellectual-property rights; evade suppression or unsubscribe requests; interfere with systems; or breach Cloudflare's or another provider's policies. You must maintain a lawful basis or valid consent where required and promptly honor opt-outs, complaints, and suppression records.

6. Orders, taxes, and refunds

Prices are shown in USD unless stated otherwise. Cloudflare, domains, taxes, and third-party services are not included. Payments are processed by Stripe. You are responsible for applicable taxes except taxes on our income.

All sales are final. Licenses and renewals are not refundable, except where applicable law requires otherwise. Contact us before purchase if you require a different contractual commitment.

7. Updates and support

Annual Licenses include updates and email support while active. Lifetime and Source Licenses include all generally released updates for the life of the product and email support for one year after purchase. Support is by email, with a first reply within one business day. Custom code, mailbox migrations, calls, Cloudflare platform changes, emergency operations, and bespoke development are not included. Support does not transfer operation of your Cloudflare account to us.

8. Customer content and privacy

You retain rights in content you submit to the website and data stored in your deployment. You grant us only the rights reasonably necessary to process website accounts, orders, support requests, and materials you intentionally send us. The Privacy Policy describes website data processing. We do not claim ownership of mailbox data stored only in your self-hosted deployment.

9. Intellectual property

MarkRelay, the website, documentation, software, and related branding are protected by intellectual-property laws. Except for rights expressly granted by your license, all rights are reserved. Feedback may be used to improve the product without an obligation to you, provided we do not publish your confidential information.

10. Disclaimer and limitation of liability

To the maximum extent permitted by law, the website, software, documentation, and support are provided “as is” and “as available,” without warranties of uninterrupted operation, deliverability, fitness for a particular purpose, or non-infringement. We are not liable for indirect, incidental, special, consequential, exemplary, or punitive damages, lost profits, lost messages, loss of data, or third-party service failures. Any aggregate liability is limited to the amount you paid us for the product giving rise to the claim during the 12 months before the event, unless applicable law requires more.

11. Changes and termination

We may update these website terms prospectively by posting a revised version and date. Changes do not retroactively reduce rights already granted under a paid software license. We may terminate access to the website or support portal for material breach, fraud, security risk, or unlawful use. Terms that by nature should survive will survive.

12. Contact

Questions about these terms or a purchase can be sent to hello@markrelay.com.
