There is no option to remove powered by Zappy Upsell Funnels from it... looks so tacky and who wants their customer to see it as a upsell funnel!!! Otherwise works easy enough.
Thank you for your genuine feedback.
We totally understand where you are coming from, and after a review, we have decided to remove our branding from the Upsell Funnel.
