Though not “delivery” per se, a quick nod to tools that help create and manage lead magnets:
Canva: Great for designing that PDF or checklist. Tons of templates to make it look professional (which implicitly makes delivery smoother – a nice PDF vs. a plain text doc).
Beacon: A tool specifically for making lead magnets (eBooks, resource libraries) and it even provides lead capture forms/landing pages. Beacon can automatically convert your blog posts into a downloadable PDF lead magnet in minutes. It’s like creation + delivery light. Could be handy if you churn out multiple magnets.
Google Analytics / conversion tracking: Once your system is up, use GA or built-in analytics of landing page tools to see conversion rates. E.g., track how many people who see your magnet page actually subscribe. Some landing page tools like Leadpages and OptinMonster show these stats and even do A/B tests to improve them.
Double opt-in confirmation tools: By 2025, many marketers still use double opt-in (subscriber must click a confirmation email before getting the magnet). Most email services handle this (ConvertKit calls it incentive email, Mailchimp calls it double opt-in confirmation). If you do use double opt-in (for list quality or legal compliance), ensure the confirmation email clearly tells them they’ll get the magnet after confirming – so they have motivation to click. Some tools (like list cleaners or verifiers) might be used before sending the magnet to ensure deliverability, but that’s advanced.
