Founders shipping a landing page or marketing site who want checklist-driven signup UX without hiring a conversion specialist.

Journey fit
Spans multiple journey phases - primary shelf plus alternate fits below.
Canonical shelf is Grow / content because the skill optimizes ongoing list building and subscriber incentives—not one-time idea research. Signup copy, placement, and lead magnets are content and conversion surfaces on the site; this subphase covers email capture UX tied to content marketing.
Where it fits
Pick inline vs hero signup on a waitlist landing page before you commit to copy and field count.
Configure a launch-week popup incentive without over-promising what the newsletter delivers.
Add a sidebar capture module on blog posts with a lead magnet aligned to article topics.
How it compares
Focused form-and-CTA playbook for capture UX, not a full lifecycle email operations skill.
