Klaviyo: Email Marketing & SMS , 1,981 reviews

I have been using this app for long and now I am not able to pay them, to upgrade my plan, we are losing important dates. Emailed them several times with no response.

Double opt in on free plan means you will have no sign ups. And there is no way around it. If you have a 3rd party sign up form (like Privy) Klaviyo will still send a sign up confirmation request once the address is synced to the list.
I don't mind paying for a good service, but not to a company that messes me up in such a sneaky way. Will sing up for a paid plan elsewhere.

Although I very much enjoy the functionality of the app itself, someone on their team has repeatedly been harassing me with phone calls and emails. Within 15 hours of signing up someone from Klaviyo has called me 3 times and sent 2 emails. As a small business owner who is busy with work as is and dealing with Covid obstacles on top of that, I do not need to be bombarded with sales calls during the work day. This is the second time I have signed up to use Klaviyo and this behavior happened to me the first time as well. I highly suggest they tone down their aggressive and unappealing sales techniques UPDATE: MAY 21, 2021. Even after repeatedly declining their services they call me multiple times a day and it is the point of harassment. I loathe this company and do not suggest even signing up because they will bother you non stop with their sales tactics.

So after paying $470 USD a month for two years, I made an error and accidentally set it to remove all customers who opened their emails zero times in the last 180 days.

It actually removed all customers who opened more than zero emails in the last 180 days. So, I contacted customer support for a backup or restore to find out there isn't one.

I had backed up our list before removing BUT all the data analytics are gone, so there was no way to sync people back into their proper flows.

What kind of tool doesn't have a backup to the previous day? I get that I made the error, but this is simply crazy.

Also they really need to improve the build features of the emails. It is 2019 now, not 2014.

You can't do "notify when in stock" or abandoned cart capturing on Shopify 2.0 themes like Dawn. Bummer.

This app is well marketed, and go to tool for e-commerce email marketing. However be cautious that installing klaviyo shopify app and inserting their .JS to your store it takes 15 website speed points out of 100 possible speed points. Our developer pointed this out that klaviyo app inserts a ton of not needed stuff to the site that kills the speed performance score of the site. WE ran a test where we removed their .JS from our store and our google speed insights score went from 20 to 35... Klaviyo please fix this

I wish their fee was more reasonable , they are extremely expensive. Gosh $300 for 13k list. Even my whole Shopify account cost $75 a month. Charging that much is ridiculous. Seems like for every 10 sales person they hired, they hired only 1 customer service. Its hideous to not be able reach customer service for a company their size and funding.

every time you contact the chat it is 8 hours, and they are not fully trained and don't have an answer to any technical issue so you have to close and start a new chat hopping you'll get somebody else! no tel support.

Was simply banned after almost 2 years. I have not received any warning, information or email. My account was simply blocked. I am more than disappointed and have not yet received any explanation or help, but am only referred further and told that it always happens. There are thousands of customers on my website every day and I can no longer work. Very disappointing.

I spent over 2 hours perfecting a campaign for the Black Friday weekend, ONLY to have my email cancelled and be notified that it will take 1 business day for my account to be reviewed by the compliance team. This means, by the time my account is no longer disabled, the black friday weekend will be over. This was my very first campaign I have ever done on my shop, but I definitely won't be recommending this app to any one else.
