I like that it's easy to use - you can just start using right away! The reporting is very detailed so we are able get exactly what reports/data points need attention or changes in our copywriting efforts; which has made us more effective at finding opportunities where there might not have been any before (or even if they were found). It would be nice when sending campaigns with multiple offers from different channels as well but this isn't much of an issue since all those options come up automatically after one campaign ends anyway :) We've used their free version first then upgraded later once things started working better without needing additional support staff costs etc.. This was great because now my colleague who doesn’t know anything about email design could create awesome designs while also being fully supported by someone familiar woth designing emails rather than having issues figuring out how everything works.
