Customising newsletter post subscription email

Hello,

I would like to create a (newsletter subscription) pop-up where visitors type their email and in response receive an email with access (in the form of a link) to a certain page on my website.

The purpose of the popup is to let potential customers access to specific content I publish for corona-time. I make it available for them as a free content, but would like them to subscribe first. I thought about using the newsletter popup for that, but that means that I need to customise the post-newsletter-subscription (verification) email.

Is that possible? otherwise how would you suggest that I do that in one step?

Thanks in advance!
