Horrible. Faites super attention à votre forfait. Je ne l'ai pas pas surveillé, résultat : 2 mois à 375 dollars pour un ROI de 50 euros max. HORRIBLE. Vous choisissez le plan gratuit, vous n'avez aucune notification par email pour le changement (le comble pour une app emailing).

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!

I’m really unhappy with this app so far. Expecting users to pay for basic human assistance is unacceptable and leaves a very poor impression.

Atrocious customer service that has no basic knowledge. They don't even know what z-index means. Also, the smart translate feature is completely buggy. It translates some parts and leaves out others. Even mixes languages within 1 email. Ive been using Klaviyo now for 2 months and was better off with Omnisend. It was also cheaper with basically the same functions. What a waste.

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.

Terrible app, we used to use it for sign ups, haven't used it since 2021, when after i deleted the app, thousands of fake emails got added to the list. I've been trying for hours to delete ALL customer's data, as well as all these bot email accounts with no success, can't even get support for it and refuse to pay to get it. the profile maintenance page is blank.

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.

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.

I've been a customer for over 4 years and I can say the support has alway been subpar but now it's terrible. I've also incurred unauthorized account charges and now they auto-sent already delivered campaigns damaging our reputation. I would seriously consider using another app for the cost alone but the lack of support really makes the decision to go elsewhere easy.
