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.

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.

AFTER 4 YEARS EVERYTHING LOST BECAUSE THEY DISABLED OUR ACCOUNT As an experience e-com founder with almost a 1M in sales. I can say Don't use this app! The last 4 years we have worked hard to creating a long list of subscribers, optimizing our flows and collection data. But out of the blue Klaviyo disabled our account without sending us any message. When we asked why they close our account they told us that one of our campaigns had a high bounce rate. When we asked to open our account and we will reduce the bounce rate. They told us it is closed permanantly. Now all our flows, data and subscriber lists are gone. Please note that if you use this app they will disable your account fast even if you are a loyal customer for 4 years. DON'T USE THIS APP. Mailchimp or Omnisend are must better service!
