What it does
Correspond is a native Mac app for email. Your mail is kept on your Mac, in a local cache you can search instantly, and the app talks directly to your mail provider — there is no Correspond server in between. It works with iCloud, Gmail (through Sign in with Google) and other IMAP accounts, and can import your accounts from Apple Mail so you do not start from scratch.
Careful with your mail
- Nothing is ever permanently deleted. Trash is a move to another folder, and it can be undone.
- Sending has a 10-second undo. Change your mind and the message never leaves.
- Drafts show up correctly everywhere. They are saved to your provider in a format that Spark, Apple Mail and your phone all display properly.
- Read it your way. Choose from reading themes and message layouts.
Built for AI agents, on a short leash
Correspond includes a command-line tool and an MCP server, so AI agents running on your Mac can search your mail and write drafts. Agents cannot send, delete, or change your accounts — sending needs your approval.
