Klaviyo: Email Marketing & SMS

Had this on multiple websites. Consolidated our websites earlier this month and tried to remove the app from the closed websites. Kept gettting an error. Reported it to Klaviyo. Help was slow and took several emails over several days to get a resolution. Was billled for two websites while waiting on further responses. Klaviyo refussed to refund charges on those despite having alerted them to the issue days earlier. They would rather lose 100% of my business then refund a charge for a service that is no longer wanted.

The app is difficult to remove and customer service is bad.

Terrible experience with Klaviyo. Not what they used to be. Customer Service took a month to get back to me! 1 MONTH. Can you believe that. They Charged me 3 times the monthly costs (supposedly someone activated this that is not anymore in the account) This should be something only the owner should be able to do! The one who pays the bills. Within hours of getting the charge FOR THE NEXT MONTH, I told them to reverse it. Klaviyo like the bad company they are now (looks like they have to show numbers because they are listed) they didnt care and responded back in a month, that there is nothing they can do.

1. First if you Bill in advance you should refund if someone gets back to you within hours.
2. Only the Account owner should have the power to increase 3x costs.
3. As a serious company you don't need 1 month to answer a customer.

If you can use another Email App. Do yourself a favor and don't use Klaviyo.

We will be definitely switching.

Klaviyo is not providing good support in V1/V2 API migrations. This update is creating problem for us.

Was once good, now awful and once of the worst options available on the Shopify app store. This is coming from having used the app for 2 years.

We've now deleted it and they're still charging us. Klaviyo - this is not how you keep your brand going. We've let our friends and groups know this company is NOT the type you want to be dealing with.

Steer clear. We'll be making this review isn't removed by them.

Fraudulent company, scamming money for Free plan!!
they invoiced me for the Free plan and say that I had a paid plan, although I changed to a Free plan 2 months ago and the money was not taken from my bank account, then suddenly I don't know why Klaviyo announced that I never had a Free plan and that's why I now pay absurdity and SHAMELESSNESS!

Be careful they are scammers!!

when I asked for a refund, they suggested Cancel subscription :D - nice service, what can I say!

A very poor customer service :(
I'm brand new, I don't have any clients yet, and when I tried the Klaviyo app, all emails went directly to spam.
so...My ability to use this app is limited by this fundamental flaw. When I wrote to Klaviyo support, I received a reply that they did not offer any help if I had a free plan and suggested that I purchase a paid plan, however, since I'm a newbie, the paid plans are not good for me....
the very unpleasant situation.. it turns out their application requires payment to work at all in my case ... ugh bad attitude :(

The app is OK, however its definitely not worth the costs or headache due to the issues you will face from their terrible customer service teams. There's no sense of trying to find a reasonable outcome for their customers and they are a company set up to take every penny from you. I would stay clear and use alternative, and much cheaper platforms.

As a struggling small business , I thought Klaviyo was the answer! But instead it created a whole load of new problems. I have a mailing list of 70,000 subscribers which I have built up over 20 years however only about 3000 are actually active - a lot of spam , Amazon and inactive emails!

Klaviyo took £500 for this immediately, it was “imperative” I sign up with them before 1st but it took them over a week to contact me to “onboard” & only then it we because I hassled them!

They then decide I needed to pay them a further £500 because their system changed or some nonsense! I have zero faith in this company, a total scam and rip off to a small business. Zero guidance , all about taking the money! Do not trust in the slightest. Have now reported them to my bank.

Very upset!

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.

Awful so far. I signed up less than a week ago and have had challenges at every turn. I've reached out several times and logged multiple support tickets and either I figure out a workaround before support responds, they don't respond or they respond with information that has absolutely nothing to do with the subject of my ticket. I have already started exploring competitors to see if they are easier to use and offer support. I am giving Klaviyo two weeks (one more to go) before making a decision.

As a seasoned e-commerce founder with nearly 1 million in sales, I strongly advise against using this app! Over the past four years, we dedicated ourselves to building an extensive subscriber list, fine-tuning our flows, and collecting valuable data. Shockingly, Klaviyo disabled our account without any prior notice. When we inquired about the reason, they pointed to a high bounce rate in one of our campaigns.

Despite our earnest request to reopen the account and our commitment to reducing the bounce rate, Klaviyo insisted on its permanent closure. The fallout is devastating – all our meticulously crafted flows, crucial data, and the carefully nurtured subscriber lists have vanished. It's crucial to be aware that this app can swiftly disable your account, even if you've been a loyal customer for four years. My recommendation: steer clear of this app and opt for Mailchimp or Omnisend for a far superior service.
