This is super easy to use, has great templates and so many options. We send weekly newsletters, and also use the abandoned cart function. Love it.

I love the option of setting up flows and being able to go straight to the app from Shopify. We're moving off of our beloved Mailchimp to give this a proper try.

I've always had some minor challenges with setting up email campaigns, but ever since I've started using Klaviyo, the operation has been easier. The platform is self-explanatory and user-friendly. Awesome 1 Team!

Klayvio is a great app. It is very easy to use. It also integrates well with other apps like Social Snowball.

Worst customer support of all times!! 3 weeks and still going on with no resolution!! Not even a simple communication to update customer with ongoing information!! 1 star is more than deserving!!

They keep charging you even if you uninstall their app, every other app on shopify automatically cancels subscription when you delete it. Wanted to delete Klaviyo on my old store and start working with it on my new store but I won't use it ever again after this.

One of the 3rd class platforms. Their support team is horrible. They do not know how to support their client. I installed their app. This app slows down our website. It is a very big issue. I uninstalled their app. I requested the customer manager to remove your snippet on my thyme file. They do not agree to remove it. I even said you should send me a request to remove the code. They completely declined my request.
I suggest to everyone not to install their app. a lot of better apps on shopify store for email marketing. I will inform the shopify app management team as soon.

This app has the worst support ever!!! My account is still disabled 4 DAYS AND I'm STILL PAYING FOR IT!!!! The support Wei Hei is the worst maybe she's still drinking and hasn't resolved my issue for 4 days. I've already cleaned the mailing list and still tells me I didn't doo anything, but if she can only think a little bit, she'll notice that a new segment was created.
