I like that it's very easy to use, has great customer service in case you need help or have any questions about using their product! It is not free but most people are willing to pay for such an amazing program. You can't beat this software at its price point!! The only thing with hexmail was having too many different email addresses from my domain set up as filters so sometimes emails would get filtered out when they should be going through correctly. This makes communication between our customers easier since we don’t have time go back over every single message looking for correct information which could take hours if done manually by myself alone.
