Klaviyo: E‑mail et SMS

Where to start... klaviyo has not been able to successfully cancel my subscription for over a year. They just continue to pull from my account. If you call them you wait on the phone foreverrrr only for the automated system to say they are having a hard time connecting to support then it hangs up on you. At one point I finally managed to get them on the phone after months!! At that point they told me the account was canceled. It still wasn't. So here I am being charged for what is seeming like the rest of my freaking life. They always say it is canceled and you'll receive a confirmation email but not until we are off the phone. It never comes so you have no proof of cancelation. This is just continuing. Total scam. There is a clear cut section showing how to cancel within the app. Except you have to confirm your email. It always says the email address is wrong although it is clearly showing your email address in the account setting. SCAM SCAM SCAM! And it never worked to begin with. Just the worst company.

Used this service for a year and a half, then they suddenly realized they don't like adult toy stores. Their Terms of Service have no mention of the adult toy industry. They immediately locked my account, and I can't export my list. I really don't care which email marketing solution to use. They are just as good anyone else, but the way they randomly lock accounts is awful. Stay away, use Omnisend or Privy. Had Omnisend for just as long and never had issues. I'll file chargebacks for the past 6 months. Have fun.

Changed my plan from Free to $20 per month used 1200 emails out of my 5000 monthly limit went to send and email campaign with 550 email addresses got a message saying upgrade plan to $30 you have exceeded your profile limit. What is this? Totally confusing just cancelled my plan. Not very happy.

Based on our experience, be very careful with Klaviyo billing. Even if you turn plan auto-upgrade OFF, Klaviyo turns ON the auto upgrade in their billing forms if you upgrade via a campaign. With this, Klaviyo will over-ride your selected plan choice, up-charging you 100% more than you agreed or needed in our case. Plus Klaviyo says they have specific policy that they do not provide refunds when you fall into their auto-upgrade bucket. So be careful to look for auto-checked boxes as we found in our experience can double your cost with no benefit and absolutely no refunds.

Customer service sucks!!!! Repeated emails for the same problem still can't be solved. Live chat takes a long time for someone to reply every time!

If I could give zero starts, I would. It's an amazing app, but they want to control your email domain and the way you email your clients. Not very versatile. They steel your money very easily with their automatic upgrades as well.

Customer service is TERRIBLE! Also, Beware if you use their SMS, you are putting your company at compliance risk. This last issue is our final straw with them. They locked (disabled) our account automatically for uploading a list of email addresses that were legally collected from an event we were involved with. So if you don't mind risking your account being shut down until one of their "customer service" reps gets to your ticket within a few days, by all means give them a try. If you want to have a reliable e-mail service, I'd recommend looking elsewhere.

Support here is the worst. We are trying to connect to Klaviyo our other shop for another country and have contacted Klaviyo at least 10 times since 2 weeks. All we get are generic replies and it seems nobody is reading our mails or helping us!!! The problem is this app haa a bug. After we try to connect another user it sends a link that is already expired the mment we click on it to confirm. Last week we waited 5 days to get another generic reply and see no interest in them actually checking the problem and helping us. This is the worst support we have experienced here on Shopify!

Just installed and got this:

Your account is disabled. More information.
Your account is under review by our Compliance Team. We're sorry for the delay - to make sure all senders have a great experience, we periodically review active accounts. You should hear from us within one business day.

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.
