One page with an email form. When someone signs up, an email goes out with a file attached as a link. No paid plan, no credit card. I tested it with a real signup — here is what it took, what nobody mentions, and when Kit's free plan is the better pick.
Funnel step form subscribed on the opt-in page. Action: Send email with the link to the file.
Every page lives on a subdomain like yourname.systeme.io. Mine was built from the start of my personal email address — visible to every visitor. You can change it under Settings → Custom domains → Edit subdomain name. Do it before you build anything.
Systeme.io does not allow @gmail.com senders. You need an address on your own domain, plus a few DNS records to authenticate it: three CNAME records and one DMARC record.
A button you add defaults to Send form. On a page without an email field, saving fails with "At least one email input is required on this page". Change the button action to Open URL.
Until you pick a template for it, people who sign up land on a page saying a thank-you page was not defined. It looks broken. Set it up before sending anyone the link.
The editor's mobile preview hid a white strip below my content that showed up on an actual phone. Setting the page background colour fixed it.
A small Powered by systeme.io badge sits in the corner of every page on the free plan.
Kit's free plan can do the core of this too. Its confirmation email can deliver a freebie when someone subscribes through a form — so if one email with a file is all you need, you do not need Systeme.io for it.

That is an affiliate link: TRYDLY earns a commission if you later pay for a plan. It costs you nothing extra. Kit is not linked here because we have no affiliate deal with them — which is also why you can trust that the comparison above is not tilted.
