Klaviyo: Email Marketing & SMS

I am extraordinarily dissatisfied with the service provided by this company. Despite their great software, the team running it cannot keep up with the company's rapid growth. When we attempted to test out the system, a minor glitch caused our account to become locked. I have sent multiple emails to the company, but I am still waiting for someone to respond. They claim that our account is locked to allow other customers to use the service, but I believe they are overwhelmed and unable to handle the volume of customers they have. This experience has left me with the impression that this company is unreliable.

Pop ups are still visible after uninstalling. There is nothing on the website that could help solve this problem, I do not recommend it

Worst experience with this app. Not working and completely useless support. Im definitely not using it again !!

They disabled my account after 5 minutes of using it. After contacting them, they send me to the Terms of Service when I didn't even have time to make changes to my account

Each email sent out to people has something like 'from klaviyo' written at the bottom. This makes it look tacky and unprofessional. I would definitely change my review if this was't there.

what a cruel app! i spent ages doing my email campaign $400 a month to send!!! this is outrageous.

I spent half a day getting everything dialed up to send emails then called their support because I was having trouble getting the email addresses into their system. They told me I could not send the emails that I wanted to send because I was importing them and there were some that didn't come from my shopify store (that came from our website's email sign-up form). Then I asked them if I could just send the shopify customer email addresses and they told me "no.".

This company is a complete and utter waste of time.

Difficult to understand, difficult to configure, non-paid payment system. A lot of useless Wicked

Very undependable app. SMS isn't sending 80% of the time. I tested with our own 2 numbers but the flows and automation don't work! Worst experience ever

Wasted hours of my day setting up my account and lists, only to find that there is no way to really remove subscribers or view/filter your subscribers (only the most recent 50?? WHY?). I had over a thousand "subscribers" from my website opt in form that were spam and I wanted to delete them but couldn't. You can only delete one person at a time, and only by searching their email address. I guess that's to be expected for a service where you pay per subscriber. Infuriatingly non-intuitive and cluttered interface. Find another service.
