Hello, Taylor Tarpley. This is the problem I encountered when I created my klaviyo account. What is the reason?

Hi there @oudlau jahng, 

Thanks for the follow up! 

Is it possible that this email address is already associated with an existing Klaviyo account that has been disabled? If so, I would recommend reaching out to our awesome Support team  to remove access to the disabled account so you can log into any other accounts you might be associated with our a new account you want to open.
