Interface is pretty self explanatory and easy to grasp. I don't find it cluttered.with unnecessary options and info like I have with other providers. They have a good overview of statistics and easy to edit templates with different integration options if needed.
Would like to be able to save and edit my own templates with only certain info that gets edited. You can duplicate past emails sent which helps, but an actual template for certain email types would be great.
Great for users who need an easy interface
I have used for several types of entities, but most recently have been using for a not-for-profit. They allow a free version for NFP which had been great and still is full of the features. The only limits are on number of contacts sent emails. We send out an email newsletter and event notices about 2 times a month to approx 300 contacts which is great.
