The Bat! Home Edition covers the basics of an e-mail client, providing what most common users demand from such a software. Anyway, it seems to offer good protection against spam, also handling encryption procedures while working with more than one e-mail server at once. A HTML-based antivirus and data execution prevention make for the latest in e-mail security.
When multiple tasks are on schedule, this app comes in handy with category sorting and message templates. Another benefit is the way it tackles accidentally deleted e-mails, always preventing data loss by message parking and backup & restore functionality.
An address book and synchronization features complete the list for this client.
