I particularly use it for our sales and marketing team. I like the email signature feature and the ability to compare software. Very helpful tools.

1. Easy Connectivity - eMill connects to any database i.e. Excel, Word, Access, SQL Server, XML 2. eMill allows you to build layouts quiet easily 3. Allows Unlimited personalization messages

The thing like the most about eMill is their target mailing system. I can make my own list of emails from my contacts and send them mails all at once but that doesn't count as spamming as I am actually sending my contacts my emails one by one.
