Super useful app, and tremendous support--Ethan answers questions promptly and thoughtfully.
Raised stars from 2 to 4. This app does integrate nicely with hubspot. The only reason it did not get a 5 star is because for some unknown reason it broke our newsletter function, and we could not get that resolved after going back and forth with their customer service for a while.
This has worked very well with out Hubspot account and allowed us to maintain automatic workflows. Very easy to install and use in Hubspot.
