Hey there! Check what list your form is sending emails to, and then look at your settings for that list. If you have Double Opt-In turned on, then it’ll auto-send an email confirmation.
There is usually a shortcut to edit that email confirmation under the double opt-in setting in the list, but you can also get there by going to Settings → other → consent pages. One of the options there should be email confirmation, which will allow you to edit what you’re seeing above.

Hi @popiinyourpocket, 

Thanks for sharing your question with the Community! 

Your fellow member @eMeg hit the nail on the head with how to change your list’s consent pages! Also, great to see you again @eMeg, thanks for helping out here! 

Our Help center also has great documentation on how to accomplish  this as well!
