An inbox that belongs to the agent
A dedicated address, a thread history, and a console a human can read — without handing an
agent your own mailbox.
An AI agent that emails from your personal mailbox inherits your identity, your contacts and
your blast radius. A dedicated inbox gives it an address of its own: mail arrives there, the
agent reads it through the API or an MCP tool, and every reply is attributable to the agent
rather than to you.
Live email, or a safe place to be wrong
Every project is either live or test, and a message never crosses between them by changing a setting.
Live inboxes
An address on agents.emailforagents.ai that sends and receives real
internet mail. Early access includes one complimentary live inbox and 100 email units a
month per verified owner identity, claimed by that identity's first eligible workspace.
Creating a second workspace does not renew it.
Test inboxes
Non-routable .mail.invalid addresses behind a fake mail transport, so they
cannot reach the internet at all. Simulate an inbound message, let the agent draft a
reply, approve it, and read the events — with no recipient anywhere. Up to 3 active test
inboxes, the last 100 messages, 10 MB, and message content expires after 7 days.
A conversation view built for a human
The console is not an afterthought on top of an API. It is where you find out what your agent has been saying.
-
Threads, not rows. Replies land back on the same conversation. Reply to one
message, or to everyone already on the thread.
-
Honest statuses. Queued, accepted by the provider, delivery updated, failed
— kept distinct, because provider acceptance is not proof that a person received anything.
-
Search that says what it covers. Stored subjects, senders and previews,
including conversations past the loaded page. Full message-body and attachment-content search
are not included.
-
Files with a gate. Attachments become available only after upload and safety
checks pass. Pending or quarantined files stay unavailable rather than silently downloading.
The limits, in numbers
These are enforced in code, not aspirations. An agent that exceeds one gets an error, not a surprise.
Per message
Up to 25 unique recipients, a 998-character subject, and 512,000 characters of body text.
Up to 10 attachments, 10 MB each and 15 MB in total. Inbound MIME is accepted up to 25 MB.
Per test project
3 active test inboxes, the most recent 100 messages, and 10 MB of retained content.
Message content expires 7 days after it arrives. Nothing is ever sent to the internet.
Per live allowance
One complimentary live inbox and 100 email units a month per verified owner identity. One
unit is one incoming message, or one recipient a provider accepts.
When the allowance runs out, sending stops. There is no overage and no surprise invoice.
Your own domain, later
Platform addresses work from the first minute. A domain of your own is a paid-plan feature, and Stripe checkout is disabled, so it cannot be bought yet.
When it opens, the DNS wizard separates the three jobs — proving ownership, sending, and
receiving — and preserves your existing mail routing unless you explicitly choose to migrate
it. That distinction matters: pointing MX records at a new provider by accident is how a
company loses a day of mail. Read the domain setup guide.
