Chesly is an independent app by Chesly, Inc. and is not affiliated with Apple, Google, Meta or any platform it connects to. Platform names and logos are trademarks of their owners.

iCloud and other IMAP providers (Yahoo, ProtonMail Bridge, Fastmail, custom domains) connect with an app password.

iCloud

At appleid.apple.com, go to Sign-In and Security > App-Specific Passwords and create one named “Chesly”.
In Chesly, go to Settings > Email Accounts > Add Email Account > iCloud Mail.
Enter your @icloud.com address and paste the password.

Other IMAP accounts

Pick Other Email in the add-account screen. You’ll need:

Email address and password (or app password if your provider requires one).
IMAP server and port (993).
SMTP server and port (587).

Search your provider’s help docs for “IMAP settings” if you don’t know the servers.

Quick references:

Yahoo: generate an app password under Account Security.
ProtonMail: run Proton Mail Bridge and connect to 127.0.0.1.
Fastmail: create an app password under Settings > Privacy & Security > Integrations.

Disconnect

Go to Settings > Email Accounts, tap the address, then tap Disconnect. Revoke the app password on the provider side too.
