For Mailspring alternatives, configure a test mailbox from the provider you actually use.
- Send, receive, search, archive, and move messages across folders.
- Test multiple accounts, aliases, signatures, and offline behavior.
- Compare keyboard shortcuts, notifications, contact handling, and accessibility.
- Verify IMAP synchronization after edits on another client.
- Review local data storage, telemetry, and backup of configuration.
An email client should not change the authoritative mailbox unexpectedly. Confirm server state from a second client before moving daily work.
