Terms of Service

1. Your account#

• You must be at least 18 and able to enter a contract, and give accurate information when you sign up.
• You're responsible for everything done with your account, API keys and connected AI agents. Keep them secure and tell us at once if one leaks.
• An account belongs to the person or business that created it. If you sign up for a business, you confirm you can bind it to these terms.

2. Using the Service#

You may use Maillayer to send email to people who agreed to receive it from you, in line with our Acceptable Use Policy and the law, including CAN-SPAM, GDPR, CASL and similar rules where your recipients live. You're responsible for your lists, your content, and having the consent you need.

To protect deliverability for everyone, new accounts have daily sending limits that rise over their first 14 days, and we may limit, pause or stop sending for an account with high bounce or complaint rates, or that breaks these terms.

3. AI agents#

If you connect an AI agent through our MCP server, it acts with your API key and on your behalf. You're responsible for what it does, including any email it sends. Review what your agent proposes before you approve sending a campaign.

4. Credits and payments#

• Maillayer is prepaid. You buy credits in one-time packs; one credit sends one email to one recipient. There is no subscription.
• Credits don't expire while your account is open. Credits for emails that fail or are dropped before sending are returned.
• If you turn on auto-recharge, you authorize us to charge your saved card for the pack you chose when your balance reaches your threshold, up to five times a day, until you turn it off.
• Payments are processed by Stripe. Prices may change for future purchases; credits you already bought are not affected.
• Except where the law requires otherwise, purchases are non-refundable. If you think you were charged in error, write to us within 30 days.
• Credits have no cash value and can't be transferred to another account.

5. Your content and data#

You keep all rights to your contacts, templates and email content. You give us the permission we need to store, process and send them to run the Service. For personal data about your recipients, you are the controller and we process it on your behalf, as described in our Privacy Policy.

6. Our responsibilities#

We work to keep the Service available, secure and delivering well, but we can't guarantee that every email reaches the inbox: that depends on recipients' mail providers. The Service is provided "as is" and "as available", without warranties beyond those the law requires.

To the extent the law allows, we aren't liable for indirect or consequential losses, lost profits or lost data, and our total liability for any claim is limited to the amount you paid us in the 12 months before it arose.

7. Suspension and closing your account#

You can stop using Maillayer at any time and ask us to delete your account. We may suspend or close an account that breaks these terms or the Acceptable Use Policy, puts other customers' deliverability at risk, or doesn't pay. When we can, we'll tell you why first. Unused credits on accounts closed for abuse are forfeited.

8. Changes#

We may update these terms. For important changes we'll give notice by email or in the dashboard before they take effect. Continuing to use the Service after that means you accept the new terms.
