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.

Shady business practice and terrible customer service The worst customer service I have ever experienced. The are quite literally holding money to ransom and their customer services team are robots which simply quote their nonsensical policies. Shady business practice, stay well clear. I paid an invoice in advance for 1 month of email flows ($100 which is criminal itself) and they did not activate my account. They are now claiming that they will hold onto this money indefinitely until we agree on a separate dispute which is much less - which they did not even bring up until they took my money. So they are in essence holding my money to ransom for a completely separate matter and refusing to provide services until in their mind it’s settled. The separate issue being that they want me to pay a month of services which I cancelled and didn’t use. Customer service is appalling, I was speaking to someone that called themselves “Ninja” (what do you expect….) and has zero sense of being reasonable. Update: Quite comical they have responded but made no comment on the fact they are still holding onto a payment I made for a service which they are not fulfilling. It’s like a company saying you owe them £5 which you disagree with, and paying them £100 for another service - they then hold onto the £100 without giving you the latter service until you pay back £5 separately. Unbelievably stupid.

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!

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.
