Connect ChatGPT to your emails
Why connect ChatGPT to your emails?
ChatGPT is already part of your daily routine for writing, brainstorming and getting things done. But when it comes to email, you are still on your own — opening your inbox, reading through threads, typing replies one by one. This back-and-forth between ChatGPT and your mail client wastes time and attention.
With MailMCP, ChatGPT gains direct access to your mailbox. You can ask it to read your latest emails, search for a specific conversation, draft a professional reply, send a message or schedule one for later. All of this happens within the ChatGPT conversation — no copy-pasting, no tab switching.
MailMCP uses the Model Context Protocol to connect your IMAP/SMTP mailbox to ChatGPT securely. Setup takes about 2 minutes through the Applications settings. Your email content flows directly between your mail server and ChatGPT — MailMCP never stores or reads your messages.
