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!

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.

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.

Absolute waste of money Absolute waste of money, they promise the moon and then when large portions don't work they refuse to issue a refund.

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.
