I got promised X by the sales… I got promised X by the sales representative. When I reached out to customer support after setting up an account, they told me this was not possible. I tried reaching out to the sales representative, didn't hear back from her. Tried reaching out to support again, didn't hear back from them either, but did get an email my ticket got closed. Worst customer service I've ever experienced.

Make them stop I'm not a customer, but someone decided to use their services to sign my email address up to receive hundreds of marketing emails. You can't contact their customer service unless you're a customer, so here I am. *UPDATE* A member of the Klaviyo team reached out to me and removed my email address from their customers' lists. A rare example of excellent customer service, and I'm grateful for it. Well done, Klaviyo!

Great ! Great tool, which allows you to optimize your business easily. A very personalized step-by-step follow-up allowed us to take control of this complete and easy-to-use tool. Quick results. Very efficient support that answered all our questions in record time, we recommend to all types of businesses! We also had a lovely time from beginning to end with Toby, Sophie and Marius who were all amazing. Thank you!

Can't recommend enough! Can't recommend enough! We upgraded to Klaviyo from a much smaller platform and are so impressed with how user friendly Klaviyo is, as well as allowing you to do some pretty clever things. Every team member I've spoken to has been super helpful and professional, ensuring we have everything we need to succeed. Love the virtual training, too.

Klaviyo is the easiest email system… Klaviyo is the easiest email system I’ve ever used and yet I’ve been able to use it to build complex automated email flows that handle all my CRM, marketing and transactional emails. The data segmentation is excellent, very granular. There are cheaper solutions out there but nothing beats the functionality and ease of use in my opinion. Plus the team at klaviyo seem to genuinely care about your success.
