Much prefer Klayvio over other providers like MailChimp or SendGrid! It does take a while to understand some more of the complex automation, but once it's set up it's pretty fire for personalization and segmentation purposes. Our account manager, Katelyn, is amazing and super knowledgeable. Our monthly meetings are incredibly useful feedback for our team. She helps us identify strategies we should be implementing to make our campaigns and flows more successful as well as robust ways of reporting. The quarterly reviews and comparative performance reports are really great and save our team a lot of time we'd usually spend generating those on our own. I will say that sometimes the support articles are lengthy, and you have to trudge through to find the exact answers you're looking for, but live chat is great.
