Frequently asked questions

What is temp mail?

Temp mail is a disposable email address you can use instead of your real one, for sign-ups, verification codes, free trials or testing. Mailsac gives you a working address instantly, with no account and no password.

How long do messages last?

Public inboxes are recycled automatically: messages are kept for a few days and only the most recent messages are shown. Don't rely on a public inbox for anything you need to keep.

Is my temp inbox private?

No. Any @mailsac.com inbox is public: anyone who knows or guesses the address can read it. Don't use it for passwords, banking or personal information. For private addresses, create a free account or use your own domain.

Can I choose my own address?

Yes. Any name @mailsac.com works the moment you use it. You don't need to create it first. Type a name in the box or use the generated one.

Can I send email from it?

No. Mailsac only receives email. Use it to receive confirmation links, one-time codes and test messages.

Can I use temp mail from code, scripts or AI agents?

Yes. Mailsac has a REST API, webhooks, WebSockets and an MCP server, so tests, scripts and AI agents can create addresses, wait for an email and read codes and links automatically.
