WinZip Courier automatically compresses and encrypts email attachments, allowing you to send lighter and more secure messages.
Still tightly integrated with Microsoft Office, WinZip Courier is best used with Outlook, and it also allows you to compress and send directly from Word, Excel and Powerpoint. In version 3.0 you can now also use WinZip Courier with web mail. Yahoo! Mail, Microsoft Live Hotmail and Gmail are supported, although unfortunately only if your browser if Internet Explorer 7 or 8.
Encryption can be set to be automatic, and has three strengths. This will give users peace of mind, although it's unnecessary for most people and email should already be secure. Compression certainly does save space and bandwidth, and can make large files look much less ominous!
WinZip Courier is especially useful for Outlook users who send lots of attachments, and its integration with Office is very useful. It's just a shame more browsers aren't supported.
