The scheduling of pop up is faulty and does not work.

So many restrictions on the new klaviyo customer hub. I can integrate gorgias, but not their live chat. Now klaviyo expects me to pay for the helpdesk feature AND also gorgias? Why? Also no mobile app for the helpdesk.

Be careful when using their email templates. They add default ALT text of the original image and include a link from some other company within some templates with animated pictures. Unfortunately, I realized this only after sending an email to my customer list, and now my customers received an email where the main clickable image leads to a completely different website. Those ALT texts and links shouldn’t be added to the templates. The services of your partner should be advertised in a different way not in a hidden way within templates!

Hectic experience. They hound you until you sign up but then dont respond after you sign up and make the payment. Been dealing with their sales person Sulaiman Lodhi and its our worse experience with an email app to date.

Facturation abusive, j'ai installé l'appli et payé un frais mensuel de 400$, je l'ai essayé 4 jours seulement avant de tout desactivé, et veillé à la desinstaller avant le nouveau cycle de facturation. Ils m'ont quand même redébité 400$. Je suis choquée!!

After subscribing and making payment, I was unable to access my account for two full days. Despite multiple attempts to reach out, their support team offered absolutely no effective solution. Extremely disappointing experience.

My Klaviyo account was hacked, and trying to recover it has been an exhausting experience. I’ve provided every possible piece of verification they asked for — except one email address I’ve never even seen before, which is the whole reason I need help in the first place. Instead of helping resolve the issue, support keeps passing me from one representative to another with no continuity or progress. For a platform that manages customer data and email security, the account recovery process should be far more user-friendly and reliable. This has made me seriously reconsider using Klaviyo at all. As it is, I did not find the app very user friendly or beneficial.

Es ist und bleibt schwierig, Ein Upgrade des Abonnements kann nur mit Kreditkarte durchgeführt werden. Wird kein Upgrade durchgeführt, kein Support der dazu was sagen kann. Wird keine Kreditkarte hinterlegt, ist kein Upgrade möglich. Das ist ja was ich hier schreibe. Man bekommt eine Antwort die nicht das Problem löst. Ihr wollt, dass ich ein upgrade durchführe, dies ist aber nur möglich wenn man eine Kreditkarte hinterlegt. Habt Ihr dafür keine andere Möglichkeit? Es bleibt bei einem Stern.

Great application with the absolute worst tech support I have ever experienced. Confused about their own product, non-responsive, and basic help takes MONTHS. I have been dealing with an issue since essentially day 1, and it still is not resolved. Expect weeks to go by without a response. Expect to repeat yourself 3-4 times every time your issue is escalated because apparently they don't read notes. Expect the help to not solve the actual issue, and have to repeat the entire process again. If you are not tech savvy and adept and implementing solutions yourself, BUYER BEWARE. You are on your own.

Horrible, money hungry company. If you don't pay up front, you get no support whatsoever. I can't even ask support a question until I hand them over my money. Sickening. Integration was not seamless at all either. Took forever and then they said our industry was prohibited when we tried to set up SMS. WHAT?? Natural Skincare?? WOW.

I only installed the app to explore the features and now they are sending me notifications that I need to upgrade to premium. I haven't even created an account. Terrible app.

The email marketing itself has personalisation for wholesale B2B business so you can refer to their business name, which is essential. That is the ONLY reason I am currently using them. But I am completely unimpressed with their billing ethics. I uninstalled Klaviyo last month on the 16th and received an email confirming I had permanently closed an account, and then received another bill on the 17th, and the 17th of this month. When you permanently close down a website Klaviyo manages to keep billing you for non-existent email services. I have been billed on two different credit cards, five days apart for supposedly the same website with different email addresses. I guess the only way to stop this is to cancel my Visa and Mastercard until it all stops, and then re-establish payment on one card, once a month. I would seriously like to find a decent replacement for Klaviyo.
