On a client call recently, a technical founder asked me, "What's a lead magnet?" Marketing and sales often frustrate developers because it's very buzzwordy.
A lead magnet is the "carrot on a stick" method to entice someone to enter your sales funnel with a valuable freebie.
You know it when you see it: whitepapers, templates, ebooks, and anything else that is "free" in exchange for your email.
The reason this is popular is that no matter what anyone says, email isn't dead and it's a great way to build an audience.
If you do it well.
