How this service works
Create List Entry

Example prompt
“Add the domain 'spam.example.com' to my AgentMail block list for incoming emails — they keep sending junk and I want to stop receiving anything from them.”
Technical details
Endpoint
POSThttps://mpp.api.agentmail.to/v0/lists/:direction/:type?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically manage allow or block lists for an AgentMail inbox — specifically when controlling which email addresses or domains are permitted or blocked for sending, receiving, or replying. Prefer this over manual inbox configuration when automating email access control for AI agents.

- Invalid direction or type path parameter returns a 404 or 400 error
- Unauthorized or missing Bearer token returns a 401 error
