Klaviyo: E‑mail et SMS

Been trying to get it to work for 2 days now but there is always something wrong with the popup either on mobile or desktop. Random buttons or text go missing for no reason when they are displayed in the customizer and then all of a sudden they're gone. Was planning on switching from mailchimp but nevermind!

I pay over $900 / month and they don't even have phone support. Constant glitches delay product launches.

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.

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.

Customer service poor.

After months of use, account suspended with no notification as to why. At least 5 days later and we're still waiting on indication despite website stating 24-48 hours for reviews to be conducted. Multiple attempts made to lodge a ticket and, only after trial and error experimenting with drop down menus, were able to succeed (Klaviyo has no option to contact support direct via email). During this time, two email enquiries also made to sales email address with no response yet received.

Otherwise a great tool, but as a business heavily reliant on email marketing, the automated bot responses in place of actual support is crippling.

For what is a professional tool that charges accordingly, professional level support and clarification should be expected.

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.

We used to love Klaviyo but like all techs these days phone support is obsolete and live chats are being abandoned during critical times. Chatbot assistance sends you into a frustrating loop of never-ending bot questions/answers. Complicated issues cannot be communicated and emails go unanswered. Chat is supposed to be live 9-5 EST but no one is ever available and you're told to just email. Will be looking to switch as the service is no longer top notch. Klaviyo always stood out on top, now they are on the bottom. Cost vs value is just not there.

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

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