I liked that every message sent has an option called "Reply" or Reply All." This allows you respond quickly without going through each recipient one at time! The ability to reply in large groups was very helpful when we're having issues responding individually within certain programs/organizations such us Health Insurance Portfolio (HIPAA). There's only 1 button instead if many so it can be more difficult than expected sometimes especially since there may not always have your cursor over them while typing out long responses. It also didn't allow me too much room before my response box would begin overlapping other boxes making writing harder due being forced close together like sardines? Also this program wasn’t designed well because some parts were hard enough where people couldn't see what they typed unless their hand actually went onto those words but even then could still easily hit multiple keys by accident thus causing confusion between different fields! So far overall i am happy using expresspigin however wish its design allowed.
