The platform and interface is very buggy depending on what browser you use. it is also pretty complicated so be prepared to be very very computer savvy. Beyond that the tools used to maintain your database of emails is extremely poor and their customer service is terrible. They will not answer your questions directly continually refer you to they're useless knowledge base... And that's assuming they just don't ignore you. It's impossible to speak to a human to resolve an issue after 2 months of trying I eventually just quit. Save yourself the time the stress.
