    This is part of the Supercharged Email playbook, built to help you get better results without guesswork.

    TL;DR

    • Content upgrades convert 5–15× better than generic "subscribe to our newsletter" forms.
    • Cross-promotion with peer brands is the cheapest paid acquisition you'll ever do (it's free).
    • Pin your lead magnet on every social profile bio, most don't and miss easy wins.
    • Test 3 form placements on your site (homepage, blog, footer) and double down on the winner.
    • A small engaged list always beats a large cold one. Don't optimize for vanity numbers.

    Frequently asked

    What's the best lead magnet?+
    Something specific that solves one problem in under 10 minutes. Checklists, templates, and short cheat sheets beat ebooks.
    Should I use paid ads to grow my list?+
    Only if your welcome sequence converts to revenue. Cold paid traffic + a weak welcome = expensive churn.
    What about exit-intent popups?+
    They work but are annoying. Use them sparingly and only with a strong incentive (10% off, free resource). Never on mobile.
    How fast should my list grow?+
    Steady beats spiky. 5–10% net monthly growth is excellent. Anything faster usually means low-quality subscribers.
    Does buying a list ever work?+
    No. It tanks deliverability for years, violates most ESP terms, and the contacts didn't ask to hear from you. Skip it.
