Choose it when a dedicated team inbox is the job. Confirm the exact checkout product because Suite and standalone Mail plan names coexist.

## Setup

**Start by confirming platform and the data path.**

Confirm this setup detail before you build a routine: Web with Chrome extension; Mac, Windows, iOS, Android apps. Then verify the processing boundary — Connects through Google/Microsoft APIs and requests email, calendar and contact permissions — and keep the first sample low-risk until the account, device, or runtime behavior matches the source description.
