- `UNISENDER_EXCLUDE` — Exclude Contact from Lists — Tool to remove contacts from specified lists or all lists in UniSender.

Recommended when subscription management is performed by sender's initiative.
- `UNISENDER_EXPORT_CONTACTS` — Export Contacts — Tool to export contact data from UniSender lists for synchronization. Use when you need to export email addresses, phone numbers, and custom fields from lists. This method works asynchronously - the response contains a task_uuid for tracking export status.

## How agents use Unisender

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

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

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