Terms of Service

Last updated: 13 June 2026

These terms govern your use of Mailjar. By using the service you agree to them. Mailjar is in beta, provided free of charge for now, and changing quickly — read §6 and §7.

1. The service

Mailjar is a receive-only inbound-email capture service. It accepts mail sent to addresses on domains you connect, parses each message, extracts data (such as one-time codes and links), and makes the result available to you through a web inbox, a REST API and an MCP endpoint. Mailjar does not send email on your behalf.

2. Your account

You sign in with Google. You're responsible for activity under your account and for keeping your API keys secret. Don't share keys you wouldn't want used on your behalf.

3. Addresses you may use

You may only capture mail for domains and addresses you own or are authorised to receive. Don't use Mailjar to intercept, collect or read mail intended for anyone else. Claimed addresses are exclusive to your account; we may reserve certain system addresses.

4. Acceptable use

You agree not to:

• use Mailjar for anything unlawful, or to store or process content you have no right to;
• attempt to bypass account scoping, access other users' data, or probe the service's security;
• use it to facilitate phishing, fraud, harassment, or to evade another party's security controls;
• place excessive or abusive load on the service, or resell capacity in a way that does so.

We may suspend or terminate accounts that breach these terms.

5. Your content

Captured mail and the data extracted from it are yours. We process it only to provide the service and under our Privacy Policy, including automatic deletion after the stated retention period. You're responsible for the content you capture and for having a lawful basis to do so.

6. Beta, availability & changes

Mailjar is offered on an "as is" and "as available" basis during beta. We don't guarantee uptime, retention beyond the stated windows, or that the service, its features or its API won't change. We may modify, suspend or discontinue any part of it. We'll try to give reasonable notice of breaking changes, but can't promise to.

7. No warranty; limitation of liability

To the maximum extent permitted by law, Mailjar is provided without warranties of any kind, and we are not liable for indirect, incidental or consequential damages, or for lost data, profits or business, arising from your use of the service. Don't rely on Mailjar as the sole store of anything you can't afford to lose. Nothing here excludes liability that can't be excluded by law.

8. Pricing

Mailjar is free during beta. We may introduce paid plans later; if we do, we'll give notice before any charges apply, and the model is volume-based rather than feature-gated (see Pricing).

9. Termination

You can stop using Mailjar and request deletion of your data at any time. We may suspend or close accounts that breach these terms or where required to protect the service or comply with the law.

10. Governing law

These terms are governed by the laws of the operator's jurisdiction, and disputes are subject to its courts, except where mandatory local consumer law gives you other rights.
