How to Connect Claude to iCloud Mail

1. Make an app-specific password

iCloud Mail doesn't accept your Apple Account password from other mail apps. It takes an app-specific password instead:

1. Sign in at account.apple.com.
2. Open Sign-In and Security, then App-Specific Passwords.
3. Create one named Postage and copy it.

Postage shows the same steps, with a button that opens your Apple Account, when you add an iCloud address.

2. Add iCloud Mail to Postage

Choose Add Account, enter your iCloud address and paste the app-specific password. Postage recognizes icloud.com, me.com and mac.com addresses and fills in Apple's servers:

Incoming (IMAP): imap.mail.me.com, port 993, TLS
Outgoing (SMTP): smtp.mail.me.com, port 587, TLS

Your iCloud mail goes straight between your Mac and Apple. Postage has no server in between.

3. Connect Claude

• Claude Desktop: Settings > Agents in Postage, then Install in Claude Desktop, and confirm Claude Desktop's install dialog. No Node.js, no config file.
• Claude Code: Settings > Agents > Claude Code > Copy Command, then run it in Terminal.

claude mcp add --transport http --scope user postage http://127.0.0.1:47913/mcp \
  --header "Authorization: Bearer YOUR_POSTAGE_TOKEN"

Full steps for both are in How to connect Claude to your email on a Mac. If you have Gmail or another account too, Claude sees all of them in one place and can work across them.

Things to ask Claude about your iCloud mail

• "What did I get from Apple about my subscription renewals this year?"
• "Find the email with the hotel confirmation for March."
• "Archive every newsletter in my iCloud inbox older than two weeks."
• "Draft a reply to my sister's last email saying we'll be there Saturday."

What Claude can change depends on the access level you give it: Read only, Organize and draft, or Full (which adds moving mail to Trash). Replies it writes open in Postage for you to send.
