Klaviyo: Email Marketing & SMS

So easy to use - wish I had installed this when I set my store up instead of Mailchimp. Great free app.

Out of all the email platforms out there. Klaviyo is my number r#1 choice. It integrates seamlessly with Shopify. 100% recommend.

great app. I recently started to use it. I think it is gonna be a killer app. So far great email tool

Its a robust app for sending email campaigns. I wouldnt call it simple to use though. Everything you have to start from scratch.

My main negative with it is the price. We have a large database of 39000 subscribers and Klaviyo is charging us USD $600 a month for the app which I think is ridiculous.

Once upon a time with traditional bricks and mortar stores, a database of 39000 was considered huge. But with ecommerce, you reach these kind of numbers in a much shorter period.
The only reason I have stuck with Klaviyo is because you can create dynamic (always updating) audiences to use in Facebook advertising.
ie. we can advertise to customers who have bought product X but not Y.

Once other email apps have this feature Im afraid I will be abandoning ship.
Sorry guys, but paying $600 a month for an email program is insane. You are being too greedy.

Stay away. Cost us a ton of money cleaning up after their mess. Customer support is spotty, at best. The IT team is disconnected from their customers, working on stealth pushes and creating havoc that we only found out days later, when we saw issues arise that had never been encountered before.

Understandably, this can happen once in a while. But with Klaviyo, this is the norm.

Not only not worth their exorbitant monthly fees but will hurt your sales as well.

Klaviyo has been an amazing tool for my small business so far! Absolutely loving it. Would recommend

love it! so far so good! If only it diddnt have a water mark! but besides that its great. I watched lots of youtube videos to figure it all out lol.

I have some difficulties with certain things, but overall Klayvio is really easy to use and their customer support is quite responsive.

Klaviyo is full of bugs. For instance, their default email preferences update does not display the current selections of the user. When I reported this to customer support, they insisted that this was not a bug at all but rather an enhancement request. Insane! I then discovered on my own that Klaviyo allows you to create your own email preferences page, but as they explicitly say, they offer no support for it, you are on your own. After struggling on my own I got it working, only to then realize that this page is only HTTP and insecure. So I spent a day figuring out some clever workarounds to solve this but then another bug has now crashed this feature completely. I am stuck waiting until tomorrow when customer support chat is available again to fix this. Email support autoreply tells me to expect to wait 48 hours. This is just one of at least half a dozen bugs I've encountered, each of which cost me days of work to find workarounds on my own. Customer support chat can go four days in a row without being available due to maintenance overlapping with the weekend. FOUR DAYS!!! When customer support chat is down for maintenance, there is no prior warning or current alert when you try to use it. It is just greyed out for no apparent reason. When this first happened to me, I wasted an hour trying to figure that out before giving up and switching to email support. The only reason I don't totally regret picking Klaviyo is I suppose other platforms could be worse or have their own set of issues. If you like frustration, you will love Klaviyo.

UPDATE: I am leaving at 2 stars because when Klaviyo works, it does the trick. But I am back to spending days getting their preferences pages working. After 18 months, it spontaneously broke and I am back to this nightmare. Klaviyo support has given up solving their bug and has asked me to use Cloudflare community postings for help in solving this.

As someone else said, "Mailchimp is for sending newsletters, Klaviyo is for making money". This is an amazing app that has huge revenue potential for your business. It's relatively easy to set up (it's very powerful, so there is a learning curve), but their support are very eager to help you out. In a nutshell, for every action someone takes on your website, you can send them a personalized email relating to that action to either strengthen your relationship with that customer or generate more revenue from them. I don't think any Shopify store owner can afford not to use even the basic features of this app.
