The Best Secure Email Client Software. Certified for Windows 10
The Bat! is a secure desktop email client for Windows, built to protect your correspondence against third-parties.
The Bat! protects your information through multiple encryption streams, with the option to keep all information encrypted on your disk, and to protect emails during communication using end-to-end encryption (E2EE). The Bat! can work without global email providers that keep your messages in the cloud, where they can be stolen. The Bat! keeps your emails on your computer to make them private. The Bat! blocks malicious code and tracking pixels that spread via email. This is a way to protect from email hacking.
The Bat! email program is able to process and store an unlimited number of messages and has no restriction on the number of email accounts accessible via IMAP, POP, MAPI protocols. The Bat! is a perfect multiple email account manager - allows you to quickly access all your email accounts in one place. The Bat! is a safe, robust and reliable mail application. It handles very large message bases quickly and with small memory footprint.
The MailTicker™ is, without doubt, one of the most powerful features of The Bat!. The MailTicker™ adds a visual indicator to your desktop similar to those stock exchange banners you may know from certain TV news channels. It shows unread messages, as defined by a set of simple options you can choose from.
This makes The Bat! the best mail app for Windows.
