What does the software or service do well? I love that Boomerang allows me to have an email come to the top of my inbox at a later time. It suggests just before a date if one is given in the actual email. I also love that it asks me if I want to follow up if I haven't received a reply from an email I sent so many days ago.
What does the software or service not do well? I wish that I had just a few more free emails -- that's about all I need.
What do you wish you had known about the software or service before using? I wish I would have found it sooner! I also didn't know that I could earn more free emails by referring people.
Have you used a competitor to the software or service? If so, how does it compare? I haven't used a competitor
