Which one is right for you?

Bloop.email vs Apple Mail

Apple Mail is free, private and already on your Mac, and it's a good app. Bloop.email is for people who want each inbox one keystroke away with ⌘1 to ⌘9, new mail that drops down from the notch, and translation built into every message.

Bloop.email vs Spark

Spark offers team features and server-side extras like push notifications, which work because Readdle's servers keep access to your account. Bloop.email has no servers, so there's nothing of yours stored anywhere but your Mac.

Bloop.email vs Outlook for Mac

Outlook is the natural choice if you live in Microsoft 365. For Gmail, iCloud and IMAP accounts it can sync a copy of your mail through Microsoft's cloud. Bloop.email always connects directly, and works the same for every provider.
