I had them for over one (1) year... I wrote many emails on Klaviyo, never had an issue. Then I wrote a campaign email about my 12yo daughter getting Covid on December 18th and our experience with it. The next thing you know, the account is disabled. When I asked why they said I violated their terms. When asked what terms... they said they could not go into specifics. The great part is that my daughter finally tested negative yesterday, December 28. The not-so-great part is that Klaviyo keeps avoiding why our account was disabled. The last message in part stated: "We reserve the right to not inform you of the reason we are terminating your account.". I have to make assumptions at this point since they will not tell me what caused it. What assumption would you make? Now I am off to use a Klaviyo competitor. I have asked Klaviyo to send me all the contacts I collected in their system throughout my time with them since I cannot even log in to download my segmented contacts. I still have not gotten a response... Would I recommend this system to my friends or Generation X people who like to talk about everything? Not at this time. I don't know if they canceled me because I talked about my Daughter getting covid, or if it was something else (and they won't even tell you so that you can correct the issue), So no, I cannot recommend it at this time. Quick Update: Klaviyo allowed me to download my contacts.

AVOID AT ALL COSTS! POSSIBLE SCAM (read this before using this service) Klaviyo has been nothing but trouble since we've started using it about two years ago. Let's start with emailing. Open rates are horrifically low when emailing our most loyal customers with this service. We were able to triple our open rates immediately by using a different service. My first issue with Klaviyo is poor support. Live chat takes a day or two to respond to simple and urgent requests and email support is appalling. In two years, I've not gotten a single written reply to any questions I've asked. All they do is send you blogs or pre-written responses that do anything but answer your questions. Waiting for simple (real) answers from Klaviyo support is so frustrating and has suspended the email side of my business by days or weeks at a time. Lastly, I could not even cancel this service without issues! YOU CAN NOT CANCEL BILLING FOR YOUR ACCOUNT! You can only 'request' to cancel billing for your account. I 'requested' to cancel billing for my account and was denied for whatever reason and therefore was billed over $550 for the next month. What kind of scam is this? The only way out of this scam was to dispute the charge. I hate disputing charges because of what disputes can do to a business but what was I supposed to do? I asked their support 6 different times to refund me and cancel my account and kept having to wait days for the same pre-written response that kept referring me to a blog. I literally begged over and over for a human to respond to me regarding this issue and they kept sending the same reply to me on how to cancel my account. I've never experienced this type of interaction with a service that costs as much as Klaviyo. I hate disputing charges and would do anything to avoid leaving poor reviews on a service because I understand how hard it is to build a business but these practices aren't safe. Proceed with Klaviyo with caution.

Hey there! So sorry to hear about these issues - it's certainly not an experience we want for any of our customers. Our support team noted there are 2 different accounts under your brand name. Can you please email feedback@klaviyo.com with details on which piece of feedback relates to which account so we can dig in and support you here? Much appreciated!

This app has the worst support ever!!! My account is still disabled 4 DAYS AND I'm STILL PAYING FOR IT!!!! The support Wei Hei is the worst maybe she's still drinking and hasn't resolved my issue for 4 days. I've already cleaned the mailing list and still tells me I didn't doo anything, but if she can only think a little bit, she'll notice that a new segment was created.

Klaviyo sucks. overpriced. also their previewer has a bug that makes it so the final email does not always match the content you set up. thanks to klaviyo, we sent an email to 5000 subs with half the text in an illegible white font. they denied any fault on their part once escalated even though the previous rep admitted to the issue. AVOID. use another cheaper service, theyre all the same

Way too expensive!!! They want to charge over $400 a month for some packages. That's highway robbery in my book. I'm gonna switch back to GetResponse which cost $120 a month with better service and features.

They keep charging you even if you uninstall their app, every other app on shopify automatically cancels subscription when you delete it. Wanted to delete Klaviyo on my old store and start working with it on my new store but I won't use it ever again after this.

While the functionality, in theory, is excellent as it allows for more sophisticated segmentation and automated flows than most mid tier email platforms will allow, the execution is shaky.

The team clearly has an admirable mission in mind yet feels incredibly junior and not too professional.

We have encountered numerous hiccups, such as the most recent example:

We were unable to send an email blast. After reaching out to support, we received an email stating that there was (an unannounced) scheduled maintenance. When we mentioned that it would have been good practice to alert businesses of this scheduled maintenance in advance, this is the reply we received:

"I've shared this feedback with the team and I believe they felt it would have been a smaller or lesser noticed UI experience. Again, we're sorry for the maintenance and inconvenience. If you need anything, please let us know!"

Clearly, it is never Klaviyo's fault. They refuse to take responsibility and place the customer at the center of their business model. This is a company run by very talented children who have yet to grow up and understand that fun functionality must be cooked up with one, and only, purpose in mind–serving their clients.

Update: I am now taking my business to Omnisend. They provide all the functionality of Klaviyo and more. Moreover, they are customer centric and understand that they are in a service oriented business.

I have purchased an upgraded plan of this app since I have 5k subs and after hours of creating a campaign the app said that my account got disabled and is under a review. They are closed on a weekend so there is no way to contact them. Very disappointed...

I do not recommend for small businesses. Too complicated to use. The moment a user gets out of a flow that you didn't want them to get out of, you're in a bind. You have to do mind gymnastics in order to figure out how to align your flows correctly. I've also had serious problems with the back-populate function, which they know they need to overhaul. I've also had people kicked out of flows, but the flow says just that they've been "skipped" - big difference between these two things. Klaviyo is very powerful and has some great features, but I'm looking forward to switching because it's simply too complicated.
