Email for AI agents
Give an agent a private link and it can send email, but only to a list of people you've approved. Everyone on the list agrees first, every email is logged, and you set the limits.
Add yourself, a colleague or a family member. Each one gets an email and decides whether to accept. Nobody is emailed by an agent without saying yes.
Each recipient or group gets private endpoint URLs, one per agent. The link only reaches that recipient, and you can pause, limit or revoke it at any time.
The agent posts a subject and a Markdown body, with files if it needs them. You see every send in the log, and can require your approval before anything goes out.

Tools: send_email, endpoint_info,
get_send_statusAn endpoint emails one recipient or one group, never an address the agent makes up.
Each endpoint, and your whole account, has a daily cap. A runaway agent stops at the limit.
Hold every email from an endpoint until you've read it and approved it.
One link that emails several people, each getting their own copy.
Agents can attach files and show images inside the message.
Agents can check whether an email was sent, bounced or is waiting, without seeing anyone's address.
You're emailed when a send fails, someone bounces, or an endpoint hits its limit.
Send through your own SendGrid account and domain if you prefer.
