Add a new sender address

Create a new email identity in seconds — through MCP tools or the dashboard. Each address is ready to send as soon as your domain is verified.

Open domain setup

Via MCP tools — fastest for automation

Create addresses programmatically. Ideal when your AI agent provisions its own identities.

  1. 01First time? Run `connect_domain` with your domain and Postmark API key, then add the 4 DNS records it returns.
  2. 02Run `get_domain_health` to confirm DNS is verified before creating addresses.
  3. 03Run `create_address` with a descriptive local-part: support, alerts, no-reply-bot, outreach.
  4. 04Send a test email and verify delivery with `list_threads`.

Via Dashboard — visual control

Point-and-click when you want to review each address before it goes live.

  1. 01Open Dashboard → Addresses and click the add button.
  2. 02Pick your verified domain and enter the local part.
  3. 03Confirm the address shows Active status.
  4. 04Optionally configure mirror rules or suppression for this address.
