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.

Great guidance from the Klaviyo Team We moved to Klaviyo from Mailchimp and the Klaviyo team really took care of us in the transition. It was quite a stressful time because we were moving platforms, moving websites and the Gmail and Yahoo new sender requirements had just come into place, but Eoin and Lucas helped us through the process with ease, humour and a great attitude so all was well in the end. We have also contacted the support team on email with an issue we were having and they got back to us really promptly and helped us to fix it straight away. We are a small business of just 4 people with no in-house tech help, so having all this support was extremely helpful. Very impressed and would highly recommend Klaviyo to any business, big or small.

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!

shocking! As a struggling small business , I thought Klaviyo was the answer! But instead it created a whole load of new problems. I have a mailing list of 70,000 subscribers which I have built up over 20 years however only about 3000 are actually active - a lot of spam , Amazon and inactive emails! Klaviyo took £500 for this immediately, it was “imperative” I sign up with them before 1st but it took them over a week to contact me to “onboard” & only then it was because I hassled them! They then decide I needed to pay them a further £500 because their system changed or some nonsense! I have zero faith in this company, a total scam and rip off to a small business. Zero guidance , all about taking the money! Do not trust in the slightest. Have now reported them to my bank. Very upset!

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.
