agentbox.id

What is agentbox.id?

agentbox.id is a dedicated email service for AI agents. It gives each user a mailbox address, password, and IMAP/SMTP connection details so an agent framework can send and receive email through standard mail protocols.

The setup flow is intentionally simple: register or log in with a personal email, receive a mailbox on first use, and paste the configuration into a compatible agent framework. The service is free per human user, but it is also constrained by mailbox limits, one-to-one inbound communication, and outbound rate caps.

What can agentbox.id do?

Agent mailbox credentials

Provides a dedicated email address and password that can be used as mailbox credentials for an agent workflow.

IMAP and SMTP access

Exposes IMAP and SMTP hosts so the mailbox can be wired into frameworks that use standard email protocols.

Standard port configuration

Shows standard connection ports for IMAP and SMTP, reducing guesswork during setup.

Mailbox retrieval for returning users

Lets returning users instantly retrieve a previously configured mailbox instead of creating a new one each time.

Automatic mailbox creation

Creates a randomly generated mailbox address and password for first-time users after login or registration.

Use Cases

“Connect an agent to email”

Use agentbox.id when an agent framework needs a mailbox it can access through standard IMAP and SMTP settings.

“Set up a reusable mailbox”

Use it to spin up a mailbox quickly after logging in, then reuse the same mailbox later without recreating the configuration.

“Keep agent mail scoped to one user”

Use it when a human account needs a dedicated one-to-one mailbox for a single agent workflow rather than broad inbox collaboration.

“Handle lightweight message exchange”

Use it for workflows where outbound message volume is modest and the mailbox does not need long-term email storage.
