The quality of their customer support is excellent and i would recommend this app to other merchants because of this. Reliable support can be crucial when trying to integrate any app to Shopify. Many thanks

I wanted to make a Christmas E-mail with a discount code for my customers. Made it like a week ago. After submitting the campaign I was prompted with a massage saying "We will personally review campaign and get in touch with you within 24h" Now its like 5 days passed and never received anything. Deleted the app and will never use it again. Just made the e-mail in google and sent it to multiple people.

Love unresponsive buttons and insanely long upload times? Use Klaviyo!
Specially made buy what seems like toddlers on a tomagotchi, klaviyo has continued to fail to do the simplest of things. Looks very fancy but very unresponsive and frustrating.
This is a one star review as Klaviyo seems to not let you show one star.

I used this app to make my very first email campaign. Awesome app! The customization is really easy to use as well!

The most frustrating service!! Upgraded my acct, created my first email and sent it out. We announced to our instagram following and had over 200 dms from people who never received it. THEY HAVE ONE JOB- and they can't even send it out the email. I also tried sending it to myself multiple times and could never find it anywhere in my email.

This app helps a lot to me. I can manage contacts and send my newsletter.
Other similar apps are not suitable for marketing. This one is Recommended!

One of best free apps in Shopify. I used for my website doublehandles.com and really love it. Good one.

So far so good, I really like the segmenting and it is easy to be up and running. I would recommend this app any day.
