Hi @Green Earth Learning and welcome to the Community!

Did you create this signup form within Klaviyo? Or is it a custom/pre-existing form that you created externally?

If you created the signup within Klaviyo, then you would have been asked to include a list upon creation here like so:

If you aren’t sure which list a Klaviyo signup form is pointing to, or you’d like to change it, you can check by editing the form and clicking on the subscribe button. The list can be changed from the Button Click Action Menu

If the form was created outside of Klaviyo (on your e-commerce platform, etc.), you would need to set up a redirect as my colleague David articulates in this Community thread:

I hope this helps, and thanks for using the Community!

Hi there, thanks for getting back to me. I think I’ve worked it out now! I had created a Sign Up separately, but I started again and it seems to have worked. Will keep these notes in case anything goes wrong! Many thanks.
