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.
Thank you for sharing your feedback and letting us know about your experience. We're sorry to hear about the trouble accessing your account and the challenges with setup and support. Our team has reached out to you via email and is eager to help out.

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.
Thank you for the feedback. Email support is available for users on our free plan for the first 60 days. Upgrading to one of our paid subscriptions will give you access to email and live chat support. As always, on our free plan, you still have access to the Klaviyo Community, where you can connect with peers and ask for crowdsource industry professionals for advice, the Klaviyo Help Center, where you can access guides regarding all aspects of your account, and the Klaviyo Academy, where you can find courses to enhance your Klaviyo knowlege.

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.

Super easy to use and fantastic return on investment. Able to segment customers any which way we want so we can keep our customer engagement personal and relevant. Easy to set up and track impact of campaigns and flows.
Thanks so much for the 5 stars! We're happy to hear that you're seeing success using segments to engage your customers, and are excited for how you'll grow with Klaviyo in the future!

I've been using Klaviyo for the last 5 years or so at various brands and what I always say to people considering the platform is that the level of support offered by the Klaviyo team is next level. I've pretty much had to learn what I know by teaching myself from articles from the help center or hopping on a live chat with an agent and they are always so wonderful and willing to help troubleshoot problems or sanity check logic when building flows, segments, etc. if they can't help you in the moment, they are always so thorough and on it with the follow ups. They're the best!
Nisolo, we really appreciate the kind words, and shouting out our support team! We'll always do our best to go above and beyond for customers like yourself! Thanks a bunch for the 5 stars.

Unbelievably non intuitive. Wouldn't text me for previewing the SMS email. Also, the form just simply wouldn't go onto my website. It didn't show up for me, would show up randomly for others, and the preview, and the final design on the website were completely different
Thank you for sharing your experience with us. That is frustrating. A member of our support team has reached out to you via email and is eager to work with you to help address these issues.

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.
Thank you for sharing your feedback. We really appreciate it. We understand how important flexibility and integration options are for your store, and we’re always working to improve the Customer Hub. If you’d like to discuss your needs in more detail, our support team is here to help and gather more insights. Feel free to reach out to us at Klaviyo.com/support.

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!
Thank you for taking the time to share your feedback, we really appreciate it. We understand how important it is for your emails to look and function just as you expect. Someone from our team has reached out directly to help address your concerns and gather more details, so we can take a closer look and support you further.

Klaviyo has been awesome for Mixology. It’s super easy to use, the segmentation is spot-on, and it’s helped us send way more personalized emails. We’ve seen better engagement, better conversions, and it just fits right into our workflow. The analytics are clear, the automations are powerful, and it’s made our marketing feel way more organized. Highly recommend!
We love to hear that you're seeing your engagement and conversions go up with Klaviyo! Thanks so much for the 5 star review, and we can't wait to see you continue to thrive!

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.
