About Spark Mail
Spark is an email client that brings multiple accounts into one inbox and sorts incoming mail so important messages come first. It adds snooze, send later, follow up reminders, a calendar, and tools for working on email with a team, such as shared drafts and comments.
The app is available on Windows, macOS, Android and iOS and uses AI features for writing and summarising, according to the store listings. It is free to download, with paid plans for premium and team functions. Prices are not in the supplied data, so see the official site. Google Play lists more than a million downloads and the iOS app lists about 82,600 ratings.
It suits people with busy inboxes and small teams that want to discuss emails without forwarding them. Spark processes mail through its own services to enable some features, so privacy-conscious users should read its policy. An account is needed to use sync and team features.
Review which AI and cloud features you want enabled, since some processing happens on the provider's servers. The developer is Readdle, while the Windows package publisher is Spark Mail Limited.
