Klaviyo: Email Marketing & SMS

Absolutely terrible service.

Quick to constantly upgrade your account which cost more money but trying to get someone to help you is nearly impossible.

Onboarding was fantastic but after that everything went downhill. Plus my conversions have never been as bad as they are with Klaviyo.

Shocking customer service from the douchebags at Klaviyo. Been with them for 3 years now. Generally all ok. However we've recently reduced the number of contacts/profiles in our email list quite significantly (by around 50,000). We expected this to have a significant effect on our monthly bills, but it seems Klaviyo is still taking out the same monthly amount as they were prior to the reduction in profiles.

I've spoken to them via live chat and email today, and was told that Klaviyo does not automatically adjust its billing down if the amount of profiles is reduced. Convenient. They were capable of automatically increasing our bills when our profile list was growing. But apparently they don't do this when the profile lists decrease.

Even so I thought that once I'd pointed out that we did reduce our list size last month, and therefore this month's bill should be significantly smaller (by about $550), they would agree to refund me the difference, but they basically told me to check my terms and conditions and get lost. They wont refund me the difference.

I am pretty dumbstruck by this. This seems very underhanded to me. Even if it's in the T's and C's to not do the right thing here stinks.

Obviously they've now lost all of our business.

Update 5th January 2025:

after a bit of back and forth with Klaviyo's billing team, and getting nowhere, I decided to leave negative reviews in as many places as I could think. Miraculously 2 days after doing this I had an email from their management offering me the refund they should have given me in the first place. Just goes to show the power of reviews I guess!

Klaviyo Inc. regarding unfair and unethical billing practices. For the billing period of December 28, 2024, to January 27, 2025, I was charged $8,180.87, despite being enrolled in a plan clearly outlined at $4,088.50.

I have provided Klaviyo with documentation confirming the agreed-upon amount for my plan. Despite this, the company has refused to issue a refund or offer any resolution. Their refusal to rectify this issue is not only disappointing but raises serious concerns about their billing practices and customer support.

Additionally, upon further investigation, I have discovered numerous similar complaints from other businesses regarding Klaviyo's unfair and unethical billing. This pattern of behavior suggests systemic issues that need to be addressed to prevent further harm to consumers.

I respectfully request that Klaviyo:

Issue a full refund of the overcharged amount ($8,180.87 - $4,088.50 = $4,092.37).
Conduct a review of their billing processes to ensure transparency and accuracy moving forward.

With their pricing changes, we have to pay TEN TIMES more than before. I received this message four days before the new price change.

If you need service and no one responds its Klaviyo. I have had the worst customer service or no service from this company.

When you try to get help there is often no one on the chat and you wait and wait and finally give up after an or hour or two.

When they want you to signup they are very fast in responding and you get impressed by how great their service is but after you sign up, no one is there to find you.

Stay away as far as you can because after sweet talk, there is no talk.

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.

An update: It is now three weeks, and Klaviyo has still not bothered to contact me and assist with my issue. Nice try suggesting it is my mail server, this has been checked, the problem lies with this email marketing company that clearly do not care enough about customer service to provide either a chat or a phone number for help.

We've been loyal Klaviyo customers for 5 years, investing $12,000 USD annually in their platform. Recently, due to a system error, the size of one of our segments was miscalculated right before our billing cut-off date, which meant we were unable to fully use the email credits we had purchased, and they expired. I contacted Klaviyo support just 3 minutes after the new billing cycle began, explaining the system error and requesting a one-time credit for the expired emails.

Considering the nature of the issue and our long-standing relationship, I expected this to be a simple, reasonable request. Unfortunately, Klaviyo refused to grant the credit for emails we had already paid for. This has been a disappointing experience and, in my view, a clear example of poor customer service. Based on this experience, I can no longer recommend Klaviyo.

the absolute WORST app I have EVER used for ANYTHING. One problem after another, you "fix" something and another issue comes up. Customer service does everything but provide the way to fix it. They all genuinely have no idea what they're doing. Do yourself a favor and look for a different app like Mailchimp or something cause this is the biggest piece of shit app I have ever used.

Sell your soul to this application. Yes, it has functionality and integration; BUT once you are on the system they own you. The design it so that it's almost impossible to unsubscribe. You can downgrade and they will automatically upgrade you, charge you, fees all the time without your permission. But they will never downgrade you, refund fees, unused.

Most importantly-- support won't help. They say it's a "self-service" platform so when it comes to just asking support to cancel your account. They won't. They send you down a rabbit hole, 10 clicks deep into pages, to find the one way you can cancel the plan.

I'm a prisoner. Having set up my flows in the system, which they don't give you any option to export, unhooking will be very labor intensive. I regret, 1,000%, my decision to partner with this application.

More importantly- support will not make CORRECTIONS to erroneous billing without double billing you! It's a total SCAM. I think this is CLASS ACTION LAWSUIT worthy... someone needs to shut these people down. They are stealing.

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.
