Why do you need the downloader's email address?

Perhaps I don't understand your goal: are you trying to collect email addresses to build a marketing list, or are you trying to give stuff away for free?

Sorry if these are dumb questions: the website doesn't really explain the business model (if there is one), or if this done out of the goodness of one's heart.

I imagine you want people to try a free template and then ask for your services to customize it? Is that how it works?

Yes. It's called a lead magnet. I have no issue giving my (business) e-mail to get such beautifully designed templates for free. There's at least $100 of value on those sites. If they start sending e-mails not relevant to me, I can simply unsubscribe.

I'm guessing since they have a contact us and are probably a design agency, they are giving away free designs to "startups" so that they can build their list of potential clients they can contact later to do branding and design work.
