What are the 3 P’s of Email Signup Forms?

The 3 P's of Email Signup Forms are Prominence, Promise, and Permission. "Prominence" refers to how visible and easily accessible the signup form is on a website. "Promise" is the value proposition or incentive offered to encourage sign-ups, clearly stating what subscribers will receive. "Permission" emphasizes the explicit consent given by users to receive emails, often through an opt-in checkbox. The other options include "Proof," which is relevant to marketing but not a core "P" for signup forms, and "Practice, Practice, Practice," which is a general idiom for improvement, not a framework for email forms.
