Total scam software! I paid $150 for it and I've been using it for less than half a month and they deactivated my account with no reasonable explanation! Emails are very difficult to reach them, they don't even want to fix the problem and refuse to refund me! Don't use it for anyone! Very disgusting, scammer, scammer, scammer!

Amazing for small business owners. Very easy to understand, setup emails and pop-ups for your website.
Creating emails is also very easy and doesn't require any design skills.

Finally, a Shopify app that just works. Only just started using this, but I'm already enjoying it and look forward to see the results.

Terrible support. They do the bare minimum to help their users and will make you use one of their partner developers if something isn't working. Any other app would try to help you with a problem you are having with their app but not Klaviyo.

The first time I signed up I was endlessly harassed by a sales rep. He even went as far as calling our store locations and harassing my staff. So I left. On the recommendation of rise.ai I gave it another try. I had to signup and pay to get any support. When I learned the program doesn't function correctly I asked for a refund. Got a robotic response from the chat agent. You need to pay hundreds of dollars to get any real support.

The best email app for ecommerce and Shopify users by far. Wish it was cheaper, but you pay for the quality.

I am still inside the free version but I really love this app compared to other email marketing tools like mailchimp for example. The technical approach and possebilities are just on another level so is the support. There is always a friendly person answering in fast fashion as soon as I need some help. They helped me a lot along the way so far. Will most propably upgrade when its time...!!!! Go for the app when in doubt!!

This is a VERY powerful app! Along with that power comes layers of complication that have a learning curve. Despite that, I was able to figure out how to use the app for the basic features I needed for my business. I have around 20K subs on my podcast, and was launching a discussion forum using Facebook Groups. I was able to capture email addresses using Group Collector which integrates with Klaviyo and Shopify. It too a bit of digging in the support chat, but I was able to figure it all out on my own, which is pretty amazing considering how illiterate I am when it comes to software. It all worked and I have profited enough to pay for Klaviyo many times over!
