The latest version of MailRemedy is 1.2 on Mac Informer. It is a perfect match for E-mail in the Communication category. The app is developed by Attila Soki.
MailRemedy is a lightweight utility designed to instantly clear the “Mail” app’s OfflineCache whenever it becomes corrupted. No advanced setup, no risky terminal commands—just a clean, guided workflow that restores normal Mail performance in seconds.
If your IMAP inbox suddenly shows multiple duplicates in “Recovered Messages,” displays a constant spinning progress indicator, or stops sending and receiving entirely, MailRemedy provides a quick, reliable solution. It’s optimized for everyday users, IT support scenarios, and anyone looking for an easy macOS mail repair tool or an automated Mail cache reset.
With just a few clicks, your Mail app is responsive again—without touching your account settings. Please note: MailRemedy cannot recover deleted or damaged emails and works only with IMAP accounts.
