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!

Timelines in this case not very fast but helpful The timelines were not as fast as other times that I have contacted support but it is still true that in this case it was more of a technical problem (within our team primarily rather than a klaviyo problem). Internal problem solved with my own insight based on guidance sent by Klaviyo support that is why I gave 4 stars.

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.

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.
