Klaviyo: Email Marketing & SMS

We had a very pushy sales rep who pressured us into installing the app within one week because only then they could provide help with setting up flows and so on. Once we installed the app he stopped replying to our messages and we never heard from klaviyo again. For support they expect you to wait in a chat for almost two hours, which is pretty crazy considering that they sell to entrepreneurs. All in all we had a pretty scammy and unprofessional experience so far. We did not expect this and are negatively surprised by the brand.

Total scam software! I paid $150 for it and I've been using it for less than half a month and they deactivated my account with no reasonable explanation! Emails are very difficult to reach them, they don't even want to fix the problem and refuse to refund me! Don't use it for anyone! Very disgusting, scammer, scammer, scammer!

Horrible customer support. I wait 2 days for a reply from someone just for them not to give any help whatsoever.

I'm sorry for the moment I replaced mail chimp.
Their service is terrible, lots of mishaps, prices are too expensive.
Very disappointed and I do not recommend them.
There are cheaper and better solutions that know how to provide excellent service and not only to make promises

A Klaviyo error meant we broke GDPR rules. It sent a campaign to audience that was not subscribed to marketing. Consider the implications of that before signing up to their service.

Customer service is virtually non existent. After raising this issue, which is surely one of the most important service levels of an email marketing service, I had to chase them more than once for a response. For such an important issue with such big implications for a business i was horrified that Klaviyo didn't respond as a priority.

Eventually I got a two line response; they released a fix that they were continuing to monitor and they apologized for what happened.

Because it was Klaviyo's error, because they didn't immediately respond to my report, because I had to chase the status on this issue, I believe Klaviyo does not take GDPR compliance seriously. This is unacceptable to my business and I cancelled my account.

When I cancelled my account I made an official complaint identifying why I was leaving. As another example of Klaviyo's poor customer service it's been a month and i still haven't heard back from them regarding that complaint.

i cant log in because the app does not work so i contacted via email and they wrote me that in order for me to contact them i need to log in to my account

HORRIBLE CUSTOMER SERVICE, VERY UNSATISFIED, DELAYED EMAIL RESPONSE, INCOMPETENT STAFF! I'm going to uninstall and go to Rare.io.
I requested a Demo and was denied because they don't have enough staffing on hands.

Their Newsletter subscription codes has a glitch when I tested it. I emailed them 7 times since April 18 and today is April 23 and have provided them my password to my website and it's still is not fixed.

I gave them clear descriptions and step by step on each defect and also provided screenshots and they kept on saying that it looks like 3 members were added. If their tech support were to read each codes line by line then they would see where the flaws were. I'm an 8 years Senior Java Developer and tested it thoroughly.

I think that this app should be very clear about their plans. Because in the end your subscription will be based on all the interactions once made on your store. And it does not matter if these profiles are useful to your business or not. If 5.000 people interact to your store but never bought a thing, you will have to pay a subscription for 5.000 profiles, which is insane expensive and might not bring you any return back. Just be aware that you will now be charged for your active email list members. Seams to be a good software, but if you don´t sign up for the very expensive subscription you can not test it. So be aware before you do all the work moving your lists to this software. It generates by it self a lot of profiles increasing the costs of subscription as they explain me in a Email. Just have in mind if you want to spend time dealing with this issue installing a new software.

The platform isn't intuitive and the customer service is mediocre at best. The final straw was when one of my flows stopped sending emails for no reason. Klaviyo customer service had no idea why and had to escalate. Also you have to pay extra for no double opt-in, which is ridiculous.

OCT 31 Update:
I just downgraded this app to a 1 because of their customer service. While is it a really good tool for those of us selling physical products on an ecommerce site, It has by far the absolute worst Customer Service of any CRM app I have used in the last 15 years.
Sometimes their automated Flows do not work. If that happens on a weekend, like it is now, then you have basically no customer support until Monday and you have lost sales for a weekend email campaign which will not send.
So what if it happens over BFCM? There will probably be no support from Wednesday afternoon till Monday morning. While it's great this company cares about their employees, the support they offer to their customers is really the worst I have ever encountered in this particular niche. When it comes to reviewing an app like this there are 2 things to consider… the app itself and the customer service. Also, the experience of the reviewer using the app. CRM apps always have a steep learning curve and so at the beginning support is needed to help us fill in the gaps where documentation is lacking. I have been using this app for about 2 years and participated in the Beta testing of their drag and drop Flows. I know my way around it but still need some help from time to time. I am writing this review so you know what are getting into before you make a purchase decision..
Like most apps, it has its quirks and that's all cool. You just need to learn them and just about every CRM app has a steep learning curve to overcome at the beginning so a good and timely support team is really critical. The app itself is a really great value. To capture all that value good customer service is needed and that is where Klaviyo falls short. In fact, over my last 20 years on ecommerce, this company’s customer service is, in my experience, one of the worst I have ever experienced. First off, they only have chat support and then... the chat hours are limited and the actual quality of the support is hit or miss. Be prepared to wait up to 45 minutes or longer to even get to a support rep. Although, to be fair, wait times, in my experience, have been as quick as 15 or 20 minutes. They do actively support the ecommerce community with fresh, innovative ideas and create videos which are totally awesome and very relevant. This is a great platform if they only had decent customer service.
I gave the rating of 2 only because of the app itself. It’s a good app with lousy support.
If you do decide to purchase this app then just know that the customer service is pretty terrible and that I am not just a newbie to this app but have been using it for about 2 years.
