Best ChatGPT Plugins for Email
ChatGPT writes a good email on its own. With an email plugin it also reads your inbox, summarizes threads, drafts replies in context and sends campaigns. Start with one of these five.
- Outlook Email: a work inbox in Outlook
- Superhuman Mail: Gmail and Outlook together, with your calendar
- Brevo: email and SMS campaigns
- Hostinger Mail: a mailbox on your own domain at Hostinger
- Mail Merge for Gmail: personalized bulk email from Gmail

1. Outlook Email
Best for a work inbox in Outlook
OpenAI’s Outlook Email plugin works with your Microsoft Outlook mail. Search messages, summarize a long thread, and pull out the exact questions a client asked so you can answer each one.
It drafts replies, such as an answer to a customer that acknowledges the problem and offers two ways forward, and keeps track of follow-ups. People search for Outlook with ChatGPT more than for any other email tool.
