I'm unable to receive verification codes when logging into my account, and I've contacted suppor and submitted tickets t multiple times but without receiving any response. Very disappoint!

I followed explicit instructions from Klaviyo support to resolve a configuration issue. That guidance resulted in service interruption and an accelerated billing cycle. Despite clear communication records, this is now being treated as a “customer-initiated change.” This is extremely disappointing and uncomfortable as a paying customer. I hope Klaviyo will review support-led actions more responsibly.

Klavio would't import my subscribed email list. It's how to import contacts from shopify instructions absolutely did not work.

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).

Disappointed in my experience with Klaviyo so far. The templates are quite poorly designed. Even the most basic templates, like for order confirmations, contain a lot of errors. I have been in constant contact with support trying to get them to include basic information that should be included automatically. For example, dynamic products were not being pulled in at all, so customers were not able to see what they purchased. This was simply an error with their template. Once we had that resolved, there was still a lot of missing information (like product variant flavors, apartment address lines, etc.) Little things that you may not notice while building, until customers complain. It took 3 support cases to get an order confirmation that simply has the correct products listed and the customers full shipping address... You cannot trust your onboarding specialist to check your emails or flows either. I had mine check our order confirmation flow multiple times before going live. She assured me we were all set and we set the flows to LIVE, and it simply did not work! She missed a key trigger that was keeping the emails from sending. We did not discover this until customers complained about missing confirmations. Again, so disappointed in the quality of the templates and the support i've been provided. While Klaviyo has all the latest and greatest features, some of the most simple and important things are severely lacking! I've used free email builders that have better designed templates.

We are unsatisfied by the set up and ease of use of the Kaviyo SMS app. We have been locked out of our account and cannot access the app or are unaware of our status and customer service has not responded to requests to unlock account. Rating Poor, unresponsive, challenging to use.

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.

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. just trying to comply with the LAW on customers data

I have paid for a plan and in the same date they have created me an invoice and i have told them that the invoice is incorrect and it needs to be changed, they said that the past invoice cant be changed, only the future ones if i modify in the settings the company name, etc. But i have requsted this in the same date when they have created my invoice, i dont understand why it cant be modify, its unbaliveble how they cant change the invoice.

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

Simplesmente não funciona no Brasil, nem deveria estar disponível.

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.

KLAVIYO SON ESTAFADORES, ROBAN DINERO, INFLAN PLANES QUE NUNCA UTILIZAS, HABLAS CON ELLOS, LO ACEPTAN SIN DISCULPAS Y NO DEVUELVEN DINERO. FATAL EMPRESA.

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.
