This app is absolutely terrible. Use an alternative.
I was drawn to this because of the free trial, but now after many hours of pulling out my hair I am deleting the app. The layout is completely ridiculous and un-intuitive. And that's not the worst part...
I signed up to my own website with my email address as a test, and it sent me draft versions of emails which I did not want it to send! If ...

I am guessing these 96 glowing reviews are small business looking for a comparable mailing system like Mail chimp, and if so - it's fine but I am also guessing that nothing went wrong and they didn't actually have to deal with Klaviyo in a 'service' area.

I did and I can (and will explain) that hands down - I would opt for Mailchimp, Constant Contact or just about ANY other system.

Wow! What an application!

Takes a little bit of time to adjust to, but overall really excellent. Once you get the hang of it, you are flying. Additionally, the support is amazing. Specific call out to Caro & Estera who were both super attentive, knowledgeable and kind.

One thing that I would like to mention is that the option to edit the header spacing on mobile needs some improvement. ...

I came across this app I'm still messing with it and I didn't think it was too difficult to maneuver. I needed a email set up to send a discount code for new subscribers and this was a great tool.

It took a little while to get used to at first but I enjoy the app. I believe information could be a little easier to find but all in all so far so good.

If you don't value your time and don't consider what tomorrow will bring, then this is the best app to start with and see if it works out for you. I began to believe many YouTubers praising this app, but I can confirm that it is completely overrated and a waste of time. After spending hours setting up Klaviyo and enjoying all the features, its number one problem is the delayed email sending. ...

I do not know why they have to keep it so hard to cancel the subscription. I've been trying to cancel the subscription for a month and I am still going to be charged for the next month. Stay away from this app.

That does a lot more than this useless piece of ....! Worst part is they take ...
