Christian Harris from ITReviewed.net did a pretty comprehensive write up on GroupMail and some benefits to using email marketing to promote businesses of various sizes.

E-mail marketing has proven very successful for those who do it right, but you need the right tools to do it. GroupMail is one such program.

Even though he thought having 4 different editions of GroupMail was over the top (and I tend to agree to a large extent), he did do a good job summarizing the breakdown in functionality in each and suitability for varying requirements.

Whether you are a small, medium or large business and you want to run an e-mail marketing campaign, GroupMail would be an ideal choice. The software looks nice, is easy to use, and has all the essential features.

In concluding he pointed out some of the pros and cons of GroupMail versus going with a web based solution, but overall a pretty fair assessment of GroupMail and its capabilities, but don’t take my word for it go over and read his review.
