Klaviyo: Email Marketing & SMS , 1,980 reviews

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.

Removed this app from the store but they are still billing me on a monthly basis. DO NOT USE!!!!!!!!

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.

I'm having a terrible experience. Here's why: I thought Klaviyo would be good because you see it everywhere and integrates with everything.
When I just started using it I was contacted by a sales person. He gave a demo and was classic sales person, using persuasive sales techniques, promising many things, only to have to find out that they don't deliver on those things. One of the main things they promise if you upgrade is that you get access to Live Chat, but the buttons to chat support are NOT EVEN CLICKABLE! So if you have problems you are basically f'd, because there's no way to get proper help. A lot of the features are glichy or don't work the way that you'd like. You get to realize that everything is built for ease of implementation for the developers and not for ease of use and functionality for the user. Honestly, I really gave this software a good try, but because I cannot vent and talk with a person, it frustrates so much that the only place I feel like I can do it is here.

Not a good experience for me. Found the app quite hard to use. Tried to implement a "don't leave" pop up on my store offering discount, it didn't work, as I tested it myself and didn't receive the discount email. Asked for help and got one response first time which didn't solve the problem, and since then Ive emailed 3 times and had no response so Im going to delete the app and try another one.

The support team need to be more responsive considering the app isn't the easiest to use.

Worst app for Email & Sms ever! They have a useless and so complicated editor for emails, you will waste hours and hours making simple edits + their customer support just takes ages to get back to you, and when they do, their feedback is just as useless as they are.
i have wasted so much time and energy on this app, so if u want to save yourself the headaches just go try alternative apps and they are many. Because Klaviyo is proven to SUCK !!!

Siamo fermi da circa 3 settimane perchè non riusciamo ad entrare con il login. Non arriva il messaggio di verifica a 6 cifre via mail, nemmno nello, spam e ho seguito le procedure che il sitema in automatico chiede di fare.
l'Assistenza non esiste non c'è nemmeno una chat sul sito per essere supportati. Dicono di mandare una mail ma non risponde mai nessuno. Ad oggi il problema non ci è stato ancora risolto e per colpa vostra siamo bloccati con il lavoro delle newsletter! davvero pessima esperienza.

The dynamic coupon in the flow automation stops working for more than a week. After I reported the issue, the support just tells me that it must be I made some changes to the coupon which causes the issue. But I am very sure no changes had been made and ask them to review my activity. Then only they acknowledge it is a bug from their side. So the support tells me that they are working to fix it (no ETA), meanwhile either use a static coupon code or stop giving coupons. 5 days passed and it is not solved yet. Absolutely dissapointed with this lousy service.
