The integration with Mailchimp works very well. Review collected by and hosted on G2.com.
I found the Pike13 to be like a team of used car salespeople. Once they made the sale, there was zero ownership taken for the "lemon" which was sold.
There were common-sense features missing. For example: there is no indication that a client is new when they are signing in.
There was no ownership taken for false promises made. For example: I was told there was ClassPass integration, but once we were finishing the onboarding process, I was told it was no longer available. After contacting ClassPass directly, I was told the integration was never offered to begin with. Review collected by and hosted on G2.com.
