Very configurable. Extremely responsive team. Simple to Ramp up.
Custom domains. Although there is a workaround for that.
Landbot.io is an all encompassing highly configurable landing page, survey, feedback and customer service toolkit so if your core product is not the landing page itself such as a SAAS product, or something you're selling on Shopify, I highly recommend this. You can also pick other tools along with this. Focus on what matters more. The product you're building. My experience using this has been pretty amazing and the team and customer support is stellar.
