Klaviyo is great. Use it every day. Customer service is excellent too.
Thank you for the 5 star review, and for shouting out our support team!

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.
Thank you for the feedback. We're always looking to improve our security processes, so we appreciate hearing your perspective.

Their customer service is excellent! Really knowledgeable and are willing to spend more time explaining more complex topics. Their response is also very prompt.
Thank you so much for shouting out our support team! We really appreciate the positive review!

An absolute POWER HOUSE of a platform for emailing, nurture sequencing, customisation to give our customers the EXACT email that converts. Worth every cent and a MUST HAVE for any business. Sure it might seem overwhelming with all of the bells and whistles but learn how to use the entire system they provide properly and it will be one of the biggest reasons your business grows.
Thanks so much for the 5 star review!

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.
We apologize for the experience you've had with our team. A member of our support leadership team has reached out to connect with you.

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.

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.
Thank you for your feedback. Would you mind submitting a request to our support team via an account access ticket here: https://help.klaviyo.com/hc/en-us/account-access-request? Once this is sent to us, our Compliance team can look into why you were prohibited from setting up SMS, and we'll get back to you ASAP.

My issue was resolved, but I experienced over 500 random bot sign-ups through Klaviyo, which forced me to spend around an extra $100 to cover the additional charges. After being billed for three months, I requested either a refund or a discount, as the issue wasn’t my fault — but my request was declined. As a loyal customer, I found this quite disappointing and lacking any gesture of goodwill. Update: I have been credited the amount by their helpful support staff, I have changed to 5 stars :)
Thank you for your feedback. A member of our Billing Support team will be reaching out to you.

Been using for many years. It's a 5-star product with a ton of capability. It's pricey, but if you have the revenue, it's worth the features. Using for email & sms. If you're considering, just do it. You won't be disappointed.
Thank you for being such a loyal customer for 5 years, and for the 5 star review. We really appreciate it!

Unfortunately, I'm not so impress with this app. The Klaviyo app is not working on my default Shopify theme page. I've been trying to get someone to review the app configuration and its taking them days to solve the problem. They are so slow at responding to issues.
