Hello,
I hope you’re doing well ?
I believe that this is a teaser. To deactivate it, I suggest that you go on your Klaviyo account and click on “Signup Forms”, then select your pop-up.
At the top of the editor, you’ll see 3 different steps : the Email Opt-in (your pop-up), the Success step (the confirmation message) and finally a Teaser.
If you click on this final step, you’ll be able to deactivate it.
I hope this was helpful.
And if you want to optimize your Klaviyo account, you can schedule a free consultation call on my calendar : https://calendly.com/standardecom/klaviyo
Cheers,
Tom
