What I like is the simplicity and ability to easily navigate through the program. Some programs I think tend to be harder to find always what you need. With Benchmark I don't see to have as much trouble compared to others.
One thing with most programs is what do you need. Like any there are limitations but we would not be using the software or have for certain purposes if it didn't meet expectations. I always recommend finding out what you need first before buying.
Try it out. For a starter corporation I feel it meets the standards but could evolve into something greater the more users it takes on.
This is great because it allows not only for e-mail marketing as a business perspective for doing outreach but also from the event planning side of things. I find both to work very well with each other. For a smaller company I think this is a great starter software depending on your needs.
