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.

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!

There onboarding was great, really structured with a weekly call and tasks in Monday.com so you know where you are at and what the next steps are. Also on hand with any more complex solutions you want to implement. Calls were useful and we regularly reviewed numbers and offered advice on what needed improving and what we can do to maximise deliverability and sender score. Overall a great experience and we've been happy with the results and advice Alex from the onboarding team has provided.
