SMTP2GO for WordPress – Email Made EasySupport response has slowed you down
Support quality is the hardest thing to read from a listing, and it is the most common reason a switch gets made. Read the most RECENT reviews on each alternative's profile rather than the lifetime average — recency is what tells you how the app is supported today, and trailing review velocity is the freshest signal AppRanks tracks.
