I like that it helps me organize my emails with filters from different companies or prospects, so I don't have to keep switching back and forth between programs! It's also helpful because if you get an error message (which happens often) all your progress goes down the drain! They need to make some changes - but they are working on this! The ease of using the program and being able to send out mass emails/emails individually is great! There isn't anything negative about this tool! If you're looking to save time by organizing multiple contacts into one place then definitely consider this product!! You will be surprised how much easier it makes things when sending out mass emails/emails individually.
