We have been very happy with the help and guidance we have received from Klaviyo in connection with integration and start-up. All questions and challenges are resolved quickly and we have had a very good start with our new email platform.

Klaviyo team was very helpful and tutoring in our onboard period and the results spoke for themselves. I was also amazed on how fast the platform is evolving, constantly improving existing and adding new features.

Hi Natalie, that's great to hear! Thank you very much for writing a review. Kind regards, Claire
Can't recommend enough! We upgraded to Klaviyo from a much smaller platform and are so impressed with how user friendly Klaviyo is, as well as allowing you to do some pretty clever things. Every team member I've spoken to has been super helpful and professional, ensuring we have everything we need to succeed. Love the virtual training, too.

I needed a more advanced email system and several people recommended Klaviyo. The functionality is impressive and the customer services team are extremely knowledgeable. The online training is also very good - I've learnt a lot. Very happy customer.

Ciao Maison, grazie mille per aver scritto una recensione su Klaviyo. Cordiali saluti, Claire
Before we had Klaviyo our emails took such a lot of time and development work to create. We were barely getting the basics out of the door. Now we have flows for everything and now that they're set up, they just run in the background. We get great reports and insight from the data. Over 50 per cent of our income now comes from our own list - it was in single digits before Klaviyo. Brilliant product.
