I really like that this tool allows us to connect with our customers through multiple channels, including social media (Facebook Messenger chatbot), SMS text message service or email campaigns in order for them have an excellent experience while visiting their website! Also it's one of my favourite tools because its user friendly - you don't need any training nor technical skill; all what we've got was knowledge about how they work as well customer support available 24/7 via phone call if needed so no problems at least from side client perspective there are none yet but still waiting until then too :) So far everything looks good although sometimes when your business grows rapidly things can be complicated here also not sure why though maybe just due some bugs etc., But overall positive feedbacks till now which i am sharing since last year already :).
