This app was easy to setup but also easy to customize. I reached out in the middle of the night to ask about a feature (wanted to have a trigger both for time and exit-intent) and got an answer within minutes. I didn't get the EXACT answer I wanted, but was told that I would be contacted once the option was implemented
lovely and speedy customer service from Tessa!
