The Bat! has been regarded as an alternative email client for advanced email users. It is often praised for its focus on security, as well as user interface customization and filtering capabilities.
The Bat! email client processes and stores an unlimited number of messages and has no restriction on the number of added email accounts.
- Encryption. The internal PGP implementation based on OpenSSL lets users encrypt messages and sign them with digital signatures. Digital keys manager is included. PGP up to version 10.0.2 is supported. The Bat! supports S/MIME via Internal Implementation or Microsoft CryptoAPI, Secure Socket Layer (SSL) v3.0 / Transport Layer Security (TLS) v1.0 and v1.1 with AES algorithm.
- Internal HTML Viewer. The Bat!’s internal viewer supports HTML 4.0 and CSS v2.0 formatting, while ignoring scripts and executable code. The Bat!’s HTML viewer blocks viruses that use the known HTML vulnerability of Microsoft Internet Explorer (such as IFRAME and Automatic Execution of Embedded MIME type).
- Safe handling of attached files. The Bat! checks attached file extensions and blocks them launching if they are suspicious. The Bat! warns users of double extension attachments and allows users to see the real extension.
- Selective download. Messages can be deleted or left on POP3 servers by setting up respective filters in the Sorting Office.
- Sorting Office. A filtering system that sorts incoming, outgoing, read, and replied messages to folders; auto-responds; replies with custom templates; forwards, redirects, prints, or exports messages; sends read confirmations; runs external programs and more.
