I like that they are constantly improving their product with new features being added all time! It's easy to use as well - just drag-drop fields into place or click links from other parts of the page. The customer support team has been amazing so far too (just recently). They have made our lives easier when we needed help getting things set up properly at first; then again later after some initial issues were resolved. We've had very few problems since starting out with them about two weeks ago, but if something does happen/arise, their fantastic service makes troubleshooting super simple. Have used this software primarily to send emails via templates built by us (or others) which include embedded Google Forms questions.
