Email capture
A follower on a platform is rented. An email address is yours. urls.bio gives you two ways to ask for one, and both are on the free plan.
The email capture block
Add an Engage block of type Email capture. It needs nothing to work, so it publishes straight away, with the title "Join the list" until you change it.
Visitors see your title, one email field, and a Join button. When someone signs up the block switches to a confirmation reading "You are on the list" and stays that way on their device, so they are not asked twice on their next visit.
Put it wherever it earns its place: near the top if the list is the point, or after the links people came for. There is nothing stopping you having more than one, though a second copy asks the same people the same question.
The whole page gate
If you would rather ask before anything else, turn on Collect emails in Settings, in the card called Page. The help text under the switch says what it does: "Visitors are asked for their email before seeing your links. Submissions land in Audience."

Visitors then meet a single prompt with your name in it, "Enter your email to see Luna Vale's links.", and under it "Your email is shared only with Luna Vale.". One field, placeholder you@example.com, and a Continue button. Once they enter an address the page opens and stays open on that device for three days.
This is a harder ask than the block. It gets more addresses per visitor and fewer visitors past the door. Which way that trade falls is worth watching in analytics, where views and subscribers sit on the same chart. You are never gated out of your own page.
The gate is the demo page's own setting, so urls.bio/demo shows you exactly what a visitor meets.
Only one gate shows at a time. If you also have a contact form set to run before the links, or any block with the 18+ switch on, the email gate comes first, then the form screen, then the age confirmation.
What gets collected
The email address and the date. Nothing else: no name, no IP address, no tracking of which link they came from.
There is no confirmation email and no double opt in. An address goes on your list the moment it is submitted. If the same address is submitted twice, the second one is quietly ignored rather than duplicated, and the visitor still gets through the gate.
Submissions are rate limited on the server: thirty an hour from one visitor, and five an hour from that visitor to any one page, so nobody can bulk-fill your list from a script.
Where subscribers land
The Audience tab in the dashboard.

Every address with the date it arrived, sortable on any column, searchable from the box at the top left, and paged 25, 50, or 250 at a time. The total sits at the top right, next to the export button, and counts your whole list rather than the page you are looking at.
Replies to a contact form block, if you use one, are listed separately below as form replies.
Exporting
Export to CSV, top right of the Audience table. You get a file called email_submissions.csv with a row per subscriber:
Email,Date Submitted,ClicksThe export covers your whole list, not just the page you are looking at or the search you have typed.
Do I own my list?
Yes. It is your list, it exports in one click as plain CSV, and you can take it anywhere without asking us. urls.bio never emails your subscribers, and it never shares them with anyone but you.
If you want new addresses to land in your email tool automatically instead of waiting for an export, see integrations.
Common questions
Does turning the gate off delete anyone? No. The switch only decides what new visitors meet. Everything already collected stays in Audience and in your export.
Someone says the page keeps asking for their email. The confirmation is a cookie on their device, tied to your page and lasting three days. A different browser, a private window, or cleared site data means a fresh ask.
Can I edit or remove an address? Form replies can be deleted from the Audience tab. Subscriber rows are the list itself: export it, edit it where you keep it, and work from that.
Do I have to tell people what I will do with their address? urls.bio tells them it goes only to you. Anything beyond that, including how you will use it, is yours to say, and worth saying in the block title.
