## How agents use Mailtrap

Inside a Definable workflow, Mailtrap is one of the tools the **Distributor specialist** can call. Example coordination patterns:

- **Researcher → Mailtrap** — the Researcher (GPT-5.5) pulls context from Mailtrap (records, threads, documents), synthesises findings, and briefs the rest of the team.
- **Writer → Distributor → Mailtrap** — the Writer (Claude Opus 4.7) drafts copy in brand voice, the Verifier passes it, then the Distributor writes the result into Mailtrap (create record, post message, draft email).
- **Designer / Engineer → Distributor → Mailtrap** — the Designer ships an asset or the Engineer ships a code change, the Distributor delivers it via Mailtrap (attach file, open PR comment, post status).

The Verifier checks every Mailtrap call. On rate limit, schema drift, or auth refresh it self-heals and retries — the workflow completes without manual intervention.
