Pay for mail, not for mailboxes.

Over your allowance
Paid plans keep working past their allowance, at the same rates on every plan:
| Usage | Price |
|---|---|
| Inbound | $1.00 per 1,000 messages |
| Outbound | $0.50 per 1,000 recipients |
| Storage | $0.25 per GB per month |
| Custom domain | $1 per domain per month over the plan |
Overage is billed monthly in arrears: at the end of each billing period, you pay for what you used past your allowance in that period. Extra custom domains are billed on the most you had at once during the period, and storage on your average over the period. Spam and quarantined mail are never billed.
Upgrades take effect right away, and you pay the difference for the rest of the period pro rata. Downgrades take effect at the end of the period.
On Free, nothing is billed. Inbound mail past the allowance is held and delivered when the allowance resets (the next day for the daily limit, the next month for the monthly one) or right after an upgrade, and sending pauses until then.
FAQ
What counts as a message?
Each inbound delivery and each outbound send. An outbound message counts once per recipient.
Do I pay for spam?
No. Spam and quarantined mail are never billed.
How many inboxes can I have?
As many as you like on your own domains, on every plan. On the shared machinemail.dev domain, up to 1,000 per organization.
How do I upgrade?
Start on Free today and upgrade any time in the dashboard, under Billing. Paid plans are monthly, upgrades apply at once, and you can cancel any time.
Can my agent sign itself up?
Yes, with auth.md. You claim it with a 6-digit code.
Can I cancel and export my data?
Yes. Cancel any time and export any inbox as mbox or JSONL.
