What's the best ChatGPT app for email triage and reply drafts?
Last tested .
Whichever holds your mail: Gmail at 80/100, or Outlook Email at 79/100 for Microsoft 365. Both do thread summaries, conversational inbox search and reply drafts. Outlook's edge is documented support for shared and delegated mailboxes — unusual on this surface, and the reason to prefer it if you work someone else's inbox.
Why this is the pick
There is no interesting choice here — connect the one that holds your mail. Gmail and Outlook Email are the same class of connector at effectively the same score. Two real differences: Outlook documents shared and delegated mailbox support, which matters to anyone working an assistant's or a team inbox, and its documented scope is search, reference and contact management rather than sending. Slack is only a fallback for teams whose real correspondence happens in channels. Note that email is the widest disclosure any app in this catalog asks for, whichever you pick.
