Use the built-in Endstack inbox, manage approved senders, and let the agent read or send email.
Every Endstack instance has a built-in email inbox that the agent can read from and send through. Messages from approved senders can also trigger the agent remotely.
Where to find email
- Open Settings → Integrations and find the Email section.
- Open the native Mail app to read, send, and manage messages from the desktop.
Inbox address
The inbox address is based on your workspace slug:
| Workspace slug | Inbox address |
|---|---|
acme | acme@endstack.co |
my-team | my-team@endstack.co |
In Settings, use the copy control to copy the address or select Open Mail to open the inbox in the Mail app.
Approved senders
The approved-sender list controls which email addresses can trigger the agent remotely.
| Control | What it does |
|---|---|
| Add sender | Adds an email address to the trigger whitelist. |
| Remove | Removes an approved-sender entry that you own. |
Only messages from approved senders can start a remote agent run through email. Mail from other senders can still arrive in the inbox and be read in the Mail app, or by the agent during a run you started, but it does not automatically trigger the agent.
An inbound email that does start a run typically appears as an external channel.
Use the Mail app
The native Mail app is the primary interface for the instance inbox. You can:
- Browse the inbox, threads, and full message content.
- Send a new message from
{slug}@endstack.co. - Reply or reply-all in an existing thread.
Open Mail from the dock or launcher, or select Open Mail in the Email section of Settings.
Agent email tools
During a run, the agent can list inbox messages and threads, read messages, send new mail, and reply or reply-all. These are the same inbox capabilities described under Tools.
Tasks can use email as an output channel—for example, to send a daily report.
