Klaviyo: Email Marketing & SMS

Has to be THE WORST customer service I have ever encountered. No chat, no phone number, only email, which is promptly ignored. I've been waiting a week for them to respond to an account access issue. Can't do much if I can't access my account. No need to point out the irony of a marketing company that doesn't seem to understand that their customers, the ones that pay for their service, need prompt, helpful support every now and then.

I think it's very shady that Klaviyo instantly charges more for additional email recipients beyond your plan level, but that when you clean your list, the plan cost stays at the higher level - unless you dig into the settings and change it back down.
A message should come up when 'Active' users drops below your biling level to ask if you want to lower your plan level. It's clearly to maximise revenue - but in an underhand way.

If you ever get hacked, do not expect the customer support to help you. I have been using Klaviyo since 2021. Recently my account was hacked and after numerous emails to customer support, I have not received any help, other than them telling me that my account is not associated with the email I'm trying to use for my login. DUH ! That's the whole problem. It was changed. I will now have to uninstall this app, lose thousands of my customers emails, which I built up for the last eight years, as well as tell my bank to block these people from taking money out of my account. Thanks a lot.

Completely unreliable software. Sometimes a campaign sends, sometimes it doesn't. Often have to keep repeating setup until it decides to send.

in sort of a nightmare situation now with adding our domain email and changing DNS records. all of our emails are landing in spam. Klaviyo said it was because we lost the confidence of the consumer... not true. this all happened in a week as we were trying to change our email.
support is zero help. we said we would need to switch email companies as being without our email marketing for weeks would seriously impair our business, they simply say... sorry to lose you. we literally spent 1-2K a month...switching to omnisend or finding another partner

Great product but support since the IPO has dropped, the support teams aren't given any powers to do anything so you can wait weeks/months from connected departments. If you need/think you might need to move quickly then choose another vendor.

There billing is deplorable. You can't make changes to your account without being double billed. They don't do proration and then if you wait to change your plan at the end of your billing so you don't get double charged they will still charge you for the highest plan and tell you that they can't help you and you aren't owed a refund of the difference.

I call that theft. I downgraded to a $100 plan and entered my info to pay for that plan. Instead of it charging me for the new $100 plan I was charged $205. I reached out immediately to get the difference refunded. I was told that I paid the bill before I made the change which was 100% false because I updated the payment information after I made the plan change.

Took about 2 months to try and get Klaviyo to integrate with Shopify tags with lots of back and forth between support who weren't able to assist me properly, rather just sending me a link to an article. We were also overcharged for 3 months and still yet to receive our money back.

Set up with Omnisend and immediately the integrations of profile data, segmentation and shopify tags were there without me even paying for anything.

Cannot be more unsatisfied with the app I've been using for all my stores. They have been charging me amounts that has not been used, and once I decide to downgrade the plan for one store that has not been receiving traffic for 2 months, they remove all the premium features which I just paid few hours ago. Also they don't have any type of customer support (I should have as I paid for the whole month already, but as I decide to downgrade to free plan for the next month, they deactivated every premium feature). I don't understand how a company of this size can do this behaviors

One those "large" companies that wont help you when you need it. Expensive to the max for this program also. If you are a "large" company also then maybe this app is for you. But for small biz - im going a cheaper route with an agent that can actually help me.
