The team at ignitum is very knowledgeable in all things account management.
They are also extremely responsive when it comes time for implementation of any new tool or process.
I have yet to find anything that has been disappointing about working with them! Their support staff does an excellent job keeping you informed as they work through issues - even if its something minor like needing more bandwidth than was originally expected. We're solving our customer acquisition problems by using A/B
Pros
Very easy access from mobile devices
Mobile app works well too.
Full control over your own data pipeline without having techs do what needs doing manually
