Klaviyo has completely transformed our email strategy for the better. We are grateful for our partnership with Klaviyo and Kate Welton, our rep, is absolutely fantastic to work with.

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.

love it, does exactly what you need it to. Much better than all the others i've used without naming any.

A little expensive if you have extensive contact base, but overall very useful and comfortable to use.

UTTER TOSH. Very poor customer service systems and buisness output systems.

We've been on Klaviyo for the last 3 years and our email program is stronger than ever. Klav allows us to easily segment and personalize content. The base platform has a lot of advanced features that are stable since the product is mature. I wish that the email capture was a little more sophisticated along with SMS. But I can tell it's getting there. Support isn't real-time but has gone above and beyond to help us out.

not a good experience.
