Give a visitor free PDF file if they insert an Email

[Goddess3]

I want to give Free PDF products for my visitors only if they enter their Email and click a button.

I want that for each Free PDF product, an email will be sent with the unique pdf file so for product X and email will be sent with file X.pdf attached to it or something like that.

I tried to look after it on Google but got overwhelmed from the amount of option lol

Do you know a free tool that can help me with what I want?

Thanks in advance 🙂

Thank you so much for the informative response my friend, I'll go with your solution and will try it.

Eventually, Can I make 1 list only for all of my free products so when a visitor will enter his email he will still get the file of the specific product depends on the product page he entered the email? or do I need to creat a seperate list for each product?

I hope so

Can you help me with this line?

"Create a form in Shopify to capture visitors' email addresses and trigger a subscription to a specific Mailchimp list."

I created a form via Mailchimp, but how to I connect it to my product page that when the visior enters email and press "submit" he will get the pdf of the product to his mail?
