I like that it is easy to use for my clients who are not tech savvy or don't have time in their day-to-day schedule (or ever) with running campaigns! We've been using this service since we started our business about 2 years ago so there isn’t much room left at all - but they do offer some free trial periods which can be helpful if you're unsure of what your needs will look/be once implemented by them as well!! Great customer support from one person only :) It's great having someone dedicated solely towards keeping up good relations between us & ensuring everything runs smoothly every step along way through implementation process.
This has saved me countless hours over other platforms out here where i'm sure many others struggle just getting things set right etc.,etc..
