Klaviyo: Email Marketing & SMS

I Installed the app due to the good reviews it had, but it started giving me problems since the 4th week, I talked to a customer agent and I spent literally 3 hours within a week sending her emails and her just giving me useless articles, my problem was related to the code, apparently klaviyo had some code problem so I got in a call with an agent and I shared screen, we tried and he didn't solve the problem, all he said is, you need to delete all the klaviyo code, yes manually, and now my newsletter when someone puts something will redirect to klaviyo saying there was a problem, I'm so disappointed, frustrated and honestly angry with this app and the customer service.
All right, apparently i cant make 1 star reviews, it wont let me submitt so i have to put 2..

Isn't Working this App! The worst ever... And they don't have any support!! :@

Update 6/9
I'm incredibly grateful to one of the support agents (Matt) who has helped me night and day since Sunday and even worked in the evenings after work hours to help me resolve this. My campaigns are now functioning as they should, but the Klaviyo popup is still showing an error message on my website when people try to sign up. I'm waiting on the development team to send an update as I've been told they are working on fixing it. I also have been told from outside sources that Klaviyo used to have amazing support but they grew too fast and are having trouble training qualified people for their support team to keep up with their growth, which makes sense. Hopefully they can hire more people like Matt who gets the job done.

Update 6/8 is that they reached out to me and are helping get it all fixed. Fortunately there is one support agent who has really saved the day for me. Still waiting to get it functioning correctly but he helped me with some of the main problems. Hopefully the problem with the popup will be fixed by their dev team soon.

I love this app in theory, and their people are generally really nice. But it is really difficult to achieve anything due to their refusal to do onboarding phone support. After several weeks I have spent countless hours trying to get my campaigns live and working correctly. Support people are really trying to help but the results are not there. Nothing is working like it should. I've been studying their guides night and day, literally it is all I have done. But it doesn't have complete information so you are left stuck with no answers. The worst part is that support people are nice but not fully trained themselves, so they give you the wrong solution that doesn't work. Weekend support is MIA. I have written 5 times to support this weekend and no response. Nothing is working. I've lost thousands of dollars in lost revenue due to the delay in being able to get my campaigns functioning correctly. So frustrated.

I need support because I'm demoing the application and nothing works. But I cant get support unless I pay for the subscription. which I don't want to do because currently nothing works. what i great business model guys. looks like I'm off to Omnisend or your competitor

Terrible customer service. Terrible app. They take your money and then close your account for NO REASON AT ALL and wont issue any refunds. They should have less than 4 star rating

I wanted to try this app because it integrates with a lot of my other apps that I have... it sucks. You have to log in EVERY SINGLE TIME and recaptcha.. My account got deactivated randomly and haven't heard anything for a week. WTF? It's confusing to use and it takes a lot of time to create a newsletter. I'm switching back over to Seguno.

It is unfortunate that they don't offer onboarding support to at least migrate and setup, after the demo call we were left with no help.

Great design and love the features. However, all emails sent from Klaviyo go to SPAM, and there doesn't seem to be any fix for this... I was about to switch to it from Mailchimp, but I will stay there as I'm sure our customers get emails from there... Once the issue is fixed I might consider switching again :)

Exactly what I needed! So much easier than other apps I've tried! It's perfect! The flows and campaigns have become easier. It took me a few hours to figure out everything, now it's just falling into place. My Shopify developer recommended it and i'm glad he did!

I love it so far. A big step up from Constant Contact and other systems that mainly do newsletters.
