Pick the lead magnet
An offer worth an email address.
Act as an email marketing strategist. My topic is [Your topic / expertise] for [Who you want on your list], and I eventually sell [What you eventually sell]. Give me 6 lead magnet ideas that solve one urgent problem quickly and lead naturally toward [What you eventually sell]. Rank them by perceived value vs effort to create.
Pro tip: Choose the magnet closest to your paid offer — it attracts buyers, not freebie-seekers.
