PARTNER email marketing hacked my Klaviyo accounts, deleted everything. I asked Klaviyo for help. 3 weeks I am emailing with support, they really don't care. I pay 10k USD a month, and they don't give a anything. NEVER use KLAVIYO, there are enough competitors that are now better. I already told support I will dispute all my bills becuase I CAN'T downgrade, and they are not assisting me how to DOWNGRADE

Any company that makes it as difficult as it can to stop using them is ethically dubious. Klaviyo (an IT comapny) does its best to make it impossible to stop a Standing Order. Its instructions to close an account are deliberately misleading and inaccurate. Dodgy. I would avoid them.

Klaviyo is overcharging... Klaviyo is currently overcharging me and hiding behind billing timing. My list has already been reduced and auto-downgrade was enabled weeks ago. Despite this, I am still being charged around $400 for a profile volume that no longer exists. Support confirmed that billing is based on a prior snapshot before the cycle resets. In other words, even after fixing your account, you are forced to overpay until their system “catches up.” That is not acceptable. This is not a user error — it is a predatory billing structure that knowingly charges customers for outdated data. My account should be billed at the correct tier based on its current state, which is approximately $100, not $400. I expect this to be corrected immediately, not at some future billing cycle. Until this is resolved, this stands as a warning: reducing your list on Klaviyo does not reduce your costs when it should.

Is it possible to give a negative review? Or zero stars? Repeatedly unsubscribing from an unscrupulous vendor’s website have been ignored-the vendor and by extension this platform continue to shove their unwanted emails into my account. I have also contacted vendor directly to tell them to remove me from all their mailings, to no avail.

After signing up and paying $70, I was required to enable MFA/2FA — there's no option to skip it. I set it up with my phone number, received the Viber verification code without issues, and successfully launched my first campaign. The next time I tried to log in, the MFA code simply stopped arriving. I tried resending it over 50 times across multiple devices and browsers — nothing. I was completely locked out of my account while my campaign was running, unable to see results or manage anything. I reached out to support, and this is where it got worse. They respond roughly every 8 hours, which means a simple back-and-forth takes days. Each time I replied, they asked for something new. The list of things they demanded "for security" was absurd: five profile email addresses from my account, the name of my last campaign, last login date, mailing address on file, other user emails, last invoice amount, last 4 digits of my payment method, last charge date, a screenshot of my bank statement showing the Klaviyo charge, a screenshot of my ecommerce admin backend with the URL visible, AND they wanted me to create a page on my website titled "Klaviyo Test" and send them the URL. I provided over 10 unique pieces of identifying information across multiple emails. Any reasonable support team would have verified my identity with a fraction of that. Instead, they kept coming back asking for more, one item at a time, with 8-hour gaps between replies. The issue is still not resolved. My business has been suffering for days because I cannot access my own account. I will be canceling permanently. If your MFA system can break after one use and your recovery process takes days of bureaucratic back-and-forth, something is seriously wrong.

TRUFFATORI! Sono degli schifosi truffatori.

Support is terrible, the system is terrible, and delivery is terrible.
