Klaviyo: Email Marketing & SMS

Much more cost effective apps available, Spent $1000 in month one and had to wait almost 2 weeks for onboarding to get in touch, I have 45,000 subscribers and was told to email 300 for the first two weeks then increase by 1000 for the next two week, needless to say their was zero return on investment, Probably a great app for a new business with less than 250 contacts

The software itself does its job well. But it's very disturbing that once you subscribe, you cannot finish the paid subscription. Klavio demands you to contact them by e-mail, but even then they keep stalling and giving empty promises for days that "someone from the team responsible for it will contact you shortly" which obviously doesn't happen.

Extremely shady

worst live support ever. I normally don't normally write reviews, but Klaviyo's customer support is so poor and it's just so not acceptable. We called, emailed many times to request help on integrating our online email form with Klaviyo. Patrick responded and said that "was going to hash that out on monday". Almost a month later, when we still could not use the email sign up contact form, we asked again, he totally forgot. We had to pull out all the past emails to proof that we did request and he did promise to help to solve the problem so that we could use start to use the email. If you have to argue with your customer support to get support; this is really hard, especially when your support totally denied it and we had to pull out our communication emails to proof that the issue is still there and we are still waiting.

Almost imposible to make it work. I installed it and emails were not sent. Followed the installation process but it did not work. A complete waste of time. Klaviyo has to understand we as dropshippers have no time to code. Make it easy to install please.

Extremely extremely hard to use and does not even save changes, no tutorials that work whatsoever. Nice one!

Just hours before my launch I was attempting my first campaign email to inform my client base that I would be taking orders and when I hit send, my account was suspended and put under review! The notice to my clients did not go out! The damage that this has done to my business and the revenue that will be lost is immeasurable! If I could give this app less than 1 star, I would!

The absolute worst customer service of any app that I used on my online store. Will not respond to your questions and when the do respond, after days gone by, they respond with a useless link to a topic that was never your question or concern in the first place.

Installing this app was the root of all disasters, basically no service, brought my website down, lost thousands of dollars in ad dollars, my website was grayed out and stuck, couldn't click on any pages, the fees were extremely expensive, When you increase email activities, he doesn't even have any reminder to increase the fee, and directly upgrades your fee in the bill. Rogue behavior, opaque charges, stay away from klaviyo, is away from disaster.

I don’t like it…I don’t like it…I don’t like it. Why on Earth is this company still using preferences pages from c. 1992. It’s 2021…time to make dem landing pages mobile responsive. Get with the time. Absolute rubbish (English accent). Absolute crap (Scottish accent).

The interface is a big confusing blob of whatever.

I can't set up anything without it not working. Finding help is so hard, it is not funny.

It is also not funny losing money because I can't set up emails properly in this stupid interface.
