How forms on your pages collect leads
Add a Form block to a page in the editor, and every submission becomes a contact in your account. Opt-in steps in funnels collect sign-ups in exactly the same way.
How fields are mapped
The block reads your fields by type. The first email field becomes the contact’s Email, the first phone field becomes Phone, and the first plain text field becomes Name. Everything else you add (dropdowns, radio buttons, checkbox groups, dates and extra text fields) is saved on the contact as a custom field named after its label.
The page must be published
Submissions are only accepted on a published page served from a connected domain. A draft page collects nothing. A hidden honeypot field quietly absorbs bot submissions.
What gets saved
Besides the fields you ask for, each submission records the time and IP address of consent, sets Source to the page slug, remembers which page it came from, and captures up to five UTM values (source, medium, campaign, content and term) if they were in the URL. A funnel step records its funnel’s slug instead.
Single opt-in is the default
With no extra setup, a new contact becomes Subscribed the moment the form is submitted and can receive your campaigns straight away.
Double opt-in is one setting
Go to Settings → Marketing and tick “Require email confirmation (double opt-in)”. With this on, a new subscriber from any form or funnel lands as Pending confirmation, receives a confirmation email and only becomes Subscribed after clicking the link. Campaigns never reach a pending contact, so the Pending tab in the contact list is worth keeping an eye on.
A few sensible safeguards apply. Someone already Subscribed is never moved back to Pending. Addresses that previously bounced or reported spam don’t go back into the confirmation queue. Someone who unsubscribed and submits a form again goes through confirmation again, because that is a genuine fresh sign-up. Repeat submissions don’t flood the inbox with more confirmations, thanks to a resend limit, and confirmations are never sent to a blocked address.
Where submissions end up
Each sign-up is an ordinary contact: you’ll find it with the list search and can open it as a contact profile, where the timeline records “Form submitted”. Tag people as they sign up, group them with tags and lists, or let the form submission trigger an automation.
