Klaviyo: Email Marketing & SMS , 1,979 reviews

DON'T GET IT! they DEActivated my account after i SET up everything for no reason, i didnt ever started advertising or emailing yet! waste of time 0 review

Trash email provider. Ruined our deliverability and billed us 300 usd more than the actual bill and when we asked for a refund they just disabled our account and we can no longer send emails to customers.

Lacks important features, but worst of all, my account was compromised. Support made me jump through a ton of hoops to prove it was my account, yet ultimately left my account frozen, with no reply from support.

I use this app and choose $60 plan, I sent some mails and SMS, no one open mails, no any use on the business, you can just ignore this app.
Why this app good? because they take a lot cost on the marketing!!!

I AM VERY ANGRY ABOUT KLAVIYO!!!!!!!! if you need to use it, plz see my words. I chose a plan that cost $60, after one month, I don't need this app, so I remove it, but it never notice me I need to change plan to free, than this app won't charge me anymore, just let me remove it, than, after a month, klaviyo just chage me $60 again, without any any notice, I even do not know why I cost $60, if you still charge me if I don't change to free plan, you should notice me BEFORE i REMOVE IT,!!!!. and it's so complicated to change free plan. I do not use this app long time, KLAVIYO should refund to me, plz solve this problem asap.

We started testing this tool for our site before we went online, and they disabled our account without any notice, you ask for a reason and they send you huge FAQ file and it's your job to figure out why they disabled you.
Very unprofessional behaviour.
We moved to Omnisend which works perfect. be careful of Klaviyo!

I'll be brief. We decided to give Klaviyo a try after working with another email marketing app for about 4 months. We decided to do this at about 10:00 pm. At about 6:00 am (that's right, you read it correctly, we had been working on new forms, segments etc. straight through the night)... at about 6:00 am, we went to preview a new form and the app kicked us out. When we tried to log back in, it says the account is inactive. No attempt to send emails. No attempts to send SMS messages. Nothing. You can imagine how we felt after spending the entire night trying to get things set up just for that to happen. Not a good first impression at all. Luckily, we had not uninstalled our previous app. Now, I'll be getting ready to go into work here in about an hour with zero sleep for the past 24 hours and absolutely nothing to show for it. By the way, the other app that we were contemplating switch over from is Omnisend. Funny thing is we have had zero issues with that app since we downloaded it. We just wanted to try an alternative to have something to compare it to. I guess it goes back to that old saying, "If it ain't broke, don't fix it."

If you don't value your time and don't consider what tomorrow will bring, then this is the best app to start with and see if it works out for you. I began to believe many YouTubers praising this app, but I can confirm that it is completely overrated and a waste of time. After spending hours setting up Klaviyo and enjoying all the features, its number one problem is the delayed email sending. Imagine, after investing hours and sessions in Klaviyo, it fails because of the main issue - sending emails. Go ahead if you really want to play Russian roulette.

Klaviyo is amazing for email marketing, with two major exceptions that negate any positive, to the point that this review is one star.

For starters, there is not a way to easily make email templates that work well with both dark mode, and normal email display settings.

The second, and far worse issue, is their customer service. I have never in my life experienced worse customer service. There is no way to contact them unless you pay, and even then it is borderline impossible to receive a response.

Given that they are the only email marketing service on Shopify that works in tandem with almost every app, I have no choice but to recommend them; but it does not come without a horrendous experience.

Some of the worst customer service in I have ever seen. We have 2 accounts with Klaviyo and things never work right. We have asked over and over for them to correct THEIR mistakes. We always get the standard answer of "we are looking into it and will get back to you within 24 hrs. THEY NEVER Do! We just lost out on all our Cyber Monday Campaign ad because their system said we went over our email limit. We have plenty of emails left before we reach our limit and they keep screwing it up. If you need help setting things up- forget it, this place is the worst at helping you. Always "Yes we are looking into it" but never any results. Its now 3 days later and we still have not gotten a response!!

They are definitely a bring you into their services in a limousine and as soon as they get your money they send you out walking. Absolutely the worst customer service on getting any help or getting anything accomplished. If you need this type of service look elsewhere.

I DO NOT RECOMMEND!
Application that makes you ashamed, very bushy application, difficult to set with many errors. Only accept compressed photos that have a pixelated appearance. I tested with another email and device and I did not receive the confirmation email with the discount code. I did everything according to the tutorial they posted on YouTube. I'm going to Shopify Mail or mail chip...I don't want to waste another 7 hours of my life!
