Ideate and design lead magnets for cold email campaigns. Covers both click-based (downloads, tools, signups) and reply-based (free trials, guarantees, done-for-you samples) campaign types. Use when a client needs a new lead magnet, when campaign-planning identifies a weak offer, or when the user wants to brainstorm offers for a specific ICP. Triggers on requests like "create a lead magnet for [client]", "brainstorm offers", "what lead magnet should we use", or when campaign-planning detects no strong lead magnet exists.
