I run several stores on Shopify and I use Klaviyo for all of them.

Klaviyo makes it easy to setup "flows" and I love how easy it is to segment customers and visitors.

But Klaviyo's support response time is awful. While their representatives are knowledgeable and helpful, it takes 24-72 hours before I can get a reply to my emails. And there is no phone or chat support.

This really becomes a problem when you have a campaign needs to run the same day but something is not working correctly.

For instance, I'm using a "product data feed" in one of my campaigns which pulls through products from my store. I have it set so 3 products pull through in the email; however, only 2 products are pulling through. I started a support ticket with Klaviyo over a week ago. With 24-48 hours in between emails, it takes forever to get something resolved. In this case, they simply quit responding last Thursday.

I'm switching back to MailChimp due to the support issues. It's too bad really, because Klaviyo is so much better on so many levels.

I had them for over one (1) year... I wrote many emails on Klaviyo, never had an issue. Then I wrote a campaign email about my 12yo daughter getting Covid on December 18th and our experience with it. The next thing you know, the account is disabled. When I asked why they said I violated their terms. When asked what terms... they said they could not go into specifics. The great part is that my daughter finally tested negative yesterday, December 28. The not-so-great part is that Klaviyo keeps avoiding why our account was disabled. The last message in part stated: "We reserve the right to not inform you of the reason we are terminating your account.". I have to make assumptions at this point since they will not tell me what caused it. What assumption would you make? Now I am off to use a Klaviyo competitor. I have asked Klaviyo to send me all the contacts I collected in their system throughout my time with them since I cannot even log in to download my segmented contacts. I still have not gotten a response... Would I recommend this system to my friends or Generation X people who like to talk about everything? Not at this time. I don't know if they canceled me because I talked about my Daughter getting covid, or if it was something else (and they won't even tell you so that you can correct the issue), So no, I cannot recommend it at this time. Quick Update: Klaviyo allowed me to download my contacts.

I use Klaviyo to manage my customer connections and it's been easy to use, has simple suggestions for quality marketing, and free + paid options. Very satisfied so far.

AVOID AT ALL COSTS! POSSIBLE SCAM (read this before using this service) Klaviyo has been nothing but trouble since we've started using it about two years ago. Let's start with emailing. Open rates are horrifically low when emailing our most loyal customers with this service. We were able to triple our open rates immediately by using a different service. My first issue with Klaviyo is poor support. Live chat takes a day or two to respond to simple and urgent requests and email support is appalling. In two years, I've not gotten a single written reply to any questions I've asked. All they do is send you blogs or pre-written responses that do anything but answer your questions. Waiting for simple (real) answers from Klaviyo support is so frustrating and has suspended the email side of my business by days or weeks at a time. Lastly, I could not even cancel this service without issues! YOU CAN NOT CANCEL BILLING FOR YOUR ACCOUNT! You can only 'request' to cancel billing for your account. I 'requested' to cancel billing for my account and was denied for whatever reason and therefore was billed over $550 for the next month. What kind of scam is this? The only way out of this scam was to dispute the charge. I hate disputing charges because of what disputes can do to a business but what was I supposed to do? I asked their support 6 different times to refund me and cancel my account and kept having to wait days for the same pre-written response that kept referring me to a blog. I literally begged over and over for a human to respond to me regarding this issue and they kept sending the same reply to me on how to cancel my account. I've never experienced this type of interaction with a service that costs as much as Klaviyo. I hate disputing charges and would do anything to avoid leaving poor reviews on a service because I understand how hard it is to build a business but these practices aren't safe. Proceed with Klaviyo with caution.

Hey there! So sorry to hear about these issues - it's certainly not an experience we want for any of our customers. Our support team noted there are 2 different accounts under your brand name. Can you please email feedback@klaviyo.com with details on which piece of feedback relates to which account so we can dig in and support you here? Much appreciated!

This app has the worst support ever!!! My account is still disabled 4 DAYS AND I'm STILL PAYING FOR IT!!!! The support Wei Hei is the worst maybe she's still drinking and hasn't resolved my issue for 4 days. I've already cleaned the mailing list and still tells me I didn't doo anything, but if she can only think a little bit, she'll notice that a new segment was created.

There is a learning curve to using this platform and the new rules with email have made that harder.

The first time I used this app I thought it was great, but then my account was disabled and that caused me great frustration. I tried to reach out to someone and it wasn't easy, but a real person did connect with me. She explained what was going on with my account. Thank you for helping me out.

Now, I think I'm back on track.
