Very straight forward set up, great for any type of audience targeting that's looking at an alternative platform over Hubspot/SalesForce; this one isn't as robust nor is it cheaper overall in regards user licenses but what they do provide can usually be done by hand. The integration points are simple enough so if someone has some technical experience then adding new fields should not take too long - we're able to quickly add things like mobile device types etc which were missing from our previous solution before without having have custom workarounds. I love that they support both mail chimp and campaign monitor so it's easy for me to switch between platforms when needed. There are some features in mail chimp that have been hard to find but not impossible. They also do great work supporting their customers, which is always appreciated! The cost of fliprss could be better if you want more than one plan per account (which we need). We use them mainly as an outbound tool to send emails from our platform to subscribers who sign up through us.
