Klaviyo: Email Marketing & SMS

I liked the app. It's a little more expensive than MailChimp, but it gives you much better control about your emails. If you not familiar with advanced email marketing you shouldn't use it. But if you want to be an email marketing guru and make from your subscribers a lof of $$$ Klaviyo the way you go!

its better than mailchimp, its very nice, you can set up a lot of thing, i love it, you must try it now

I've worked with a ton of emailing platforms and companies and Klaviyo has, hands down, been the best. The integrations allow us to tap into a wealth of customer information that has made us a better organization while also allowing us to grow explosively, and I'm not exaggerating. Because of the email tools this platform provides, we are experiencing the best Q1 in three years. Not to mention, every time I've had any issue with the platform (wanting to send emojis in subject lines, getting higher than normal spam alerts, my template isn't working like I want, etc.) the support from the Klaviyo team has been prompt, courteous, and outstanding. -- I could go on. 10/10 would recommend.

Seriously I don't get why people use them. We switched from Omnisend and have nothing by problems. Onboarding was terrible, the staff just did not want to know. Since we have been using it we have found a number of issues and the support is so poor (especially if you are out of the US), I honestly don't know what you are paying for. We will be moving back to a provider who has better service and a better product, this one is rubbish.

Just got this app and was looking forward to setting it up.
About 30 minutes in I get this: "Your account is disabled".
They'll get back to me within 1 business day.

What? Why? The hell did I do wrong? How am I supposed to evaluate your product when you literally ban me within the hour of using it?

Hell of a first impression lemme tell you that.

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.

Great app! Easy to use. Awesome customer service!

Great app couldn't do without it tbh. would highly recommend it, Rich in features and low on price

if there is an app that makes you want to break your laptop then this would be it, go ahead break it.
