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 you use this app, they will spam your customers with unwanted emails. There is a "flows" option where you can design the emails that are sent and choose when they are sent.
The email from my email flow WAS NOT sent to me, and instead I got a "confirm you would like to subscribe.... enter text here etc" which I DO NOT want my customers to receive. It honestly baffles me what could have possibly been going through the minds of the idiots who designed this app. I would very much like to meet them in person one day to ask what on earth they were thinking.

Long story short DO NOT USE THIS APP

I've used this app and find it very good but with some exceptions.
1) The interface is not easy to figure out. It needs to be simplified.
2) You can't delete any of the campaigns that you don't want. This creates a lot of clutter.
I like apps created for ease of use and where the operator has full control. This is not one of them. However, it is much better than MailChimp which I uninstalled because it was very frustrating. It would never update properly.
Although Klaviyo needs work, I still recommend it. Good support.

Ceci est un MUST pour ma solution en ligne. Mon entreprise a récemment démarré et, autant que je sache, Klaviyo constituera un pas énorme dans la bonne direction avec le CRM. Facile à utiliser et support goid. Merci

I used this app to help me market my small online boutique. The templates they have are so professional and exquisite. Very pleased!

prompt reply response. Im getting the hang of this app, after all Im seeing it is user friendly... cool features.. like the service. do recommend

This is a MUST for my online solution. My business has recently started and as far as I can see Klaviyo will be a huge step in the right direction with CRM. Easy to use and goid support. Thsnk you

I really like Klaviyo a lot. It's user friendly and has very good support. I use it to send emails to my e-commerce customers and their templates make it very easy. Learning to use the flows and I think that holds a lot of potential. Seems like there's endless options. I've tried a couple other top name automated marketing companies. Highly recommend Klaviyo over those.

This a Great app! this app is helpful to me Because I work a full time Job and have an online store so this is convenient when I need to have emails sent out to my customers and I am at work just click and send. thank You.

This app is a must have! The support staff replies SO FAST and there are a ton of helpful step by step videos for navigating.

This app is very easy to use and it's great so far, just waiting for response per my first campaign. Great Job!
