Use case overview

The writer plugged a custom Gemini Gem into Workspace Studio flows that run in the background, summarize Gmail messages and create draft replies to review and send.

Reported experience

  1. What they did

    The writer opened Google Workspace Studio, created a new flow from a Google template with a Gmail trigger, and added the Ask a Gem step so a custom Gem processes incoming mail in the background. She used the Gem's output to create Gmail draft replies, which she reviewed and sent herself. She ran a test, then switched the flow on.

  2. How it went

    The flow worked after a test run, and she says the setup felt intuitive. She claims about 10 hours a week saved, but the article gives no measurements.

  3. Worth knowing

    The Gem must be grounded in Google Drive files, because Gems that use extensions such as YouTube or Maps don't show up. Work accounts also need an admin to enable Gemini actions.

Example prompts

When new emails arrive in Gmail matching [label, sender, or topic], it should summarize each one in [2] sentences and create a draft reply in [my tone]. Drafts should only be saved, never sent.
