Klaviyo is one of the best platforms around and the customer service is top notch. From the smallest detail to the biggest problem imaginable, they always seems to assist in ensuring my email program is running on all cylinders. I would recommend 1000 times over!

Terrible experience with Klaviyo. Not what they used to be. Customer Service took a month to get back to me! 1 MONTH. Can you believe that. They Charged me 3 times the monthly costs (supposedly someone activated this that is not anymore in the account) This should be something only the owner should be able to do! The one who pays the bills. Within hours of getting the charge FOR THE NEXT MONTH, I told them to reverse it. Klaviyo like the bad company they are now (looks like they have to show numbers because they are listed) they didnt care and responded back in a month, that there is nothing they can do.

1. First if you Bill in advance you should refund if someone gets back to you within hours.
2. Only the Account owner should have the power to increase 3x costs.
3. As a serious company you don't need 1 month to answer a customer.

If you can use another Email App. Do yourself a favor and don't use Klaviyo.

We will be definitely switching.

Was once good, now awful and once of the worst options available on the Shopify app store. This is coming from having used the app for 2 years.

We've now deleted it and they're still charging us. Klaviyo - this is not how you keep your brand going. We've let our friends and groups know this company is NOT the type you want to be dealing with.

Steer clear. We'll be making this review isn't removed by them.

Klaviyo is easy to use and ultra intuitive. The features for email and sms flow is a must have
