AFTER 4 YEARS EVERYTHING LOST BECAUSE THEY DISABLED OUR ACCOUNT As an experience e-com founder with almost a 1M in sales. I can say Don't use this app! The last 4 years we have worked hard to creating a long list of subscribers, optimizing our flows and collection data. But out of the blue Klaviyo disabled our account without sending us any message. When we asked why they close our account they told us that one of our campaigns had a high bounce rate. When we asked to open our account and we will reduce the bounce rate. They told us it is closed permanantly. Now all our flows, data and subscriber lists are gone. Please note that if you use this app they will disable your account fast even if you are a loyal customer for 4 years. DON'T USE THIS APP. Mailchimp or Omnisend are must better service!

Helpful & Supportive Joanna was extremely helpful in identifying multiple issues I was having and providing different solutions and recommendations. She responded quickly and patiently walked me through the steps in fixing the problem.

Terrible after sale service Terrible after sale service. They are extremly pushy in meeting sales goals and pressure you to get Klaviyo. We switched over from Mail Chimp and the onboarding process has been a total nightmare. They promise you tech support and guidance, but after you onboard, all they say is that you can read their online instruction with minimal support. We only onboarded for a one-hour call, and after that, we had to work on the chart flows, so after we were stuck and needed more questions, no one answered. We've been waiting for months and both the sales girl and the onaboaring person do not email back. It's extremely frustrating.

Klaviyo's support team is outstanding! Klaviyo's support team is outstanding! They're friendly, patient, and willing to walk you through any scenario. Even if you just need someone to confirm your work.
