Signup Form with List and Segment

Hi @David Thornton,

You are correct - best practice is to have one main mailing list of all of your opted in contacts. This way it is easier to pull contacts from a single list when creating audiences for campaign sending.

You can still have these contacts that subscribe through a signup form route to the same list as all of your other opted in contacts and just trigger a Welcome series for subscribers who came through specific signup form(s). When a subscriber signs up through a Klaviyo signup form, they will automatically get the $source profile property associated with their profile. In order to locate/change the $source associated with a signup form, you can click on the submit button of the form in Klaviyo’s signup form editor and see it nested under ‘Hidden Fields.’

You’ll want to add the flow filter to your welcome flow “properties about someone where $source=x.” This will ensure that the welcome series with the coupon code will only trigger for subscribers that came through specific signup form(s).

Hope this helps!
