The ability for it integrate with other systems is great as well! It's easy enough that someone who has no experience can use without any issues at all - very simple platform which makes onboarding new users easier than most others I've used (especially if you have an existing CRM integration). If there were more integrations available or better training materials out in public then this would be even higher up my list but right now their documentation seems lacking so far when compared against competitors such as Bronto/Salesforce Marketing Cloud etc., Their customer service also isn't quite where they need it yet either though we're working towards getting things fixed here too over time :) Great product overall however please do continue developing further features into future releases because currently only being able to target certain groups within segments does not make sense especially since our system allows us access.
