Using Zapier (or something else) to send content after collecting email

I would like to provide some free, downloadable content on my site, but I want to require people to submit their email before receiving it. Basically free downloads as lead magnets.

I messaged Squarespace help, and they suggested using Zapier to send people the doc(s) after they fill out a form on my SS site. Does anyone know of a (preferably-two-step) Zap that would enable me to do this?

Or if there's a completely different way to do it, I'm all ears.
