Hey @jop
The only reason I can think of is that you API keys might have been compromised or misused. I would suggest regenerating new API keys and update them in all your integrations. Go to your Klaviyo account settings and review all active integrations. Ensure that only your legitimate websites and apps are connected. If you find any unfamiliar or suspicious integrations, disconnect them immediately.
I would suggest contacting Klaviyo support ASAP via chat support
Ensure your account is secure with strong passwords and enable two-factor authentication if available.
I hope you get this resolved soon.
Cheers

Hey @ArpitBanjara
Thank you very much for your reply! I have checked my integration and the only thing connected is my website, nothing else.
I also have two-factor authentication but I’ll change my password anyway.
I am talking to Klaviyo support at this moment, hopefully it will be resolved soon.
Thank you very much!
Cheers
