Disposable by design
Inboxes that clean up after themselves
Give an address a lifetime of 10 minutes or 10 years. When it expires, it stops accepting mail and its data disappears on schedule. Extend or keep it with one click.

Email inboxes
for teams
Connect your domain once, then create addresses in one click or one API call. Squadmail receives the mail, pulls out the codes and links, sorts everything automatically — and hands it to your team, your tests or your AI agents in real time.

Mail that sorts itself

Approve before agents send
Agents draft, you decide. Review, edit and approve every outgoing email — or let them send freely.

Why teams switch to Squadmail
Most email-testing tools and agent email APIs cap or charge per inbox. Squadmail charges for email volume — create as many addresses as you like.

Questions & answers
Why is there no free plan?+
Free email accounts attract spammers, and that would hurt deliverability for every customer. Hobby costs a symbolic $1 a month ($10 a year) — nothing for real users, but enough to keep abuse out. Self-hosting stays completely free.
What counts as an email?+
Every message that arrives in one of your inboxes counts as one received email. Emails you send or reply with count towards your sent quota. Creating inboxes is free and unlimited.
What are smart AI labels?+
Labels you describe in plain English (“is this a job application?”) that are applied automatically to incoming mail. They run on every email on every plan — no separate quota. Rule-based labels work alongside them.
What happens if I go over my plan?+
No surprise bills. We let you know when you get close to your limit, and you can upgrade with one click. Your plan never upgrades itself.
Why does Hobby have a daily limit?+
It keeps the price at $1. You can receive up to 1,000 and send up to 300 emails per month — at most 100 received and 20 sent per day — and you send from your own custom domain. Starter and above have no daily limit, only the monthly volume of the plan.
Can my AI agents use Squadmail?+
Yes — that’s what it’s built for. Connect Claude, Cursor or any MCP client in one step, or use the REST API from your own agent framework.
Which domain do my inboxes use?+
Your own — on every plan. Add a domain or subdomain (for example agents.yourcompany.com), publish the DNS records we show you, and every address on it becomes available, optionally with catch-all. There is no shared Squadmail domain: your mail and your reputation stay yours.
Can I cancel anytime?+
Yes. Plans are monthly or yearly, and you can downgrade or cancel from your settings at any time.
Is there a self-hosted version?+
Yes. Squadmail is open source (MIT) and deploys to your own Cloudflare account in one click. The cloud version saves you the setup, updates and operations.
Connect your domain once. Every inbox after that is one click.
Add a few DNS records — we walk you through it and check them for you. Start with Hobby for $1 a month and upgrade when your team or your agents need more.
