I like that it's super easy to set up my account and customize features to fit our needs- there is no learning curve or complicated process as other products require.
We've been able to streamline many processes such as sending out automated emails with custom content (like reminders) and having all incoming messages stored in one place so we can easily see what came in throughout the day. It would be nice if you could send images larger than 2mb but overall it has served us well. Sending mass mailings and using multiple different programs to accomplish this task was time consuming (and prone to mistakes).
