A direction for the design
Use a direct offer, readable terms and restrained motion. A simple signup can fit a considered purchase; games should support the brand rather than trivialize product decisions.
Set expectations clearly
Do not ask for sensitive health details in an email-signup field. Keep medical claims out of unreviewed popup copy. This form is not a health assessment or personalized recommendation tool.
Connect the promise to the follow-up
Review the destination list and first email alongside the signup copy. The person should receive the category of communication they actually agreed to.
Write your design brief
Provide your supplements campaign references, exact offer, audience and approved wording. Select a layout and trigger, review the generated version on mobile, and run a consenting test signup before publication.
