PowerSearch searches every mail account you own in a single query — Gmail, Outlook, iCloud, Yahoo, M365, Exchange, standard IMAP — instead of switching apps or searching one inbox at a time. It syncs headers only, never message bodies, entirely on-device, so a tool built to find your email doesn't also become somewhere your email content ends up. Results grouped by sender, filterable by date, with one-tap Flag and Forward. From the team behind MailBroom. 7-day free trial.
