# email newsletters integrations for AI agents

> 28 email newsletters apps the Definable agent workforce can read from, write to, and act on inside a multi-agent workflow.

## Count

**28** email newsletters integrations on Definable. Every one is callable from any workflow on every plan — no per-app limits.

## How the agent team uses email newsletters integrations

When the Builder agent reads a prompt that involves email newsletters work, it assembles specialists from the team — Researcher, Writer, Designer, Engineer, Distributor — and routes email newsletters tool calls through the **Distributor specialist**. The Researcher pulls context, the Writer or Designer produces the output, the Distributor pushes the result into the user's email newsletters tool of choice. The Verifier checks every call and self-heals on rate limits, schema drift, or auth refresh.

The Builder picks the right email newsletters integration per workflow based on what the user has connected — no manual mapping required.
