Email

Collect email addresses that pass a format check, and optionally make the respondent prove the inbox is theirs with a six-digit code before they continue.

The Email block collects an address and checks its shape before the form moves on, so a typo is caught by the respondent rather than by your bounced reply. With Verify email on it goes one step further and sends a code to the address, which the respondent types back into the form. Use it for newsletter sign-ups, contact forms, and any form where the address is the whole point.

Add an Email block

Open the insert menu with / and choose Email. Give it a question above the box or a placeholder inside it; the box's own placeholder reads name@example.com until you change it. A block with neither is listed as "Untitled email field" in your results. See How to name question fields.

A respondent whose entry is not shaped like an address sees "Please enter a valid email" under the box when they press Next or Submit. Press Preview in the editor to try it.

Email settings

Open the settings from the handle at the block's left edge.

Make it required

Required refuses a submit while the box is empty; the respondent sees "Please enter a value".

Required switched on, and the empty box refused with Please enter a value

Add a default answer

Default answer fills the box before the respondent arrives. Type an address, or pick a hidden field from the menu so a link that carries email= in its query string opens with the box filled. See Pre-populate form fields.

Verify emails

Verify email makes the respondent prove the address is theirs before the form accepts the page. A submit with an unverified address on it is refused on the server as well as in the browser, and the server checks the block on the version the respondent loaded and on the latest one, so an old link cannot skip a verification you turned on later.

How it works for the respondent:

Once the address passes the format check, a Verify button appears inside the box
Pressing it sends a six-digit code to that address, and the form says "A verification code has been sent to your inbox."

The six-digit code as the message that reaches the respondent's inbox

The respondent types the code into the Verification code box that opens under the field
On a match the field reads "Email address verified" and the form moves on

Under the code box the form asks "Didn't receive a code?" with a Resend link, which becomes usable after a short countdown ("Resend in 30 seconds"). A code is good for one hour and for a handful of wrong guesses; past either, the form says so and offers a new one. Asking again always replaces the previous code, so only the newest one works.

Who the code comes from

There is no per-form sender for verification mail: every code goes out from the same address, whatever a form's own From: is set to.

Domain-specific email verification

To let only one company's addresses through, pair Verify email with a rule that hides the way forward for everyone else:

Turn on Verify email in the Email block's settings
Press Add conditional logic on the same block

Add conditional logic pressed on the email block

In the When row pick the Email field, the comparator Does not end with, and type your domain, @yourcompany.com
In the Then row choose Hide button to disable completion

Hide button to disable completion chosen as the rule's action

Put the rest of the form on a following page, so the check gates everything after it

The rest of the form moved onto a following page, so the check gates everything after it

Publish and test it with an outside address: the Next button disappears the moment the address is typed, and reappears when it ends with your domain. See Conditional logic.

Where the address goes next

An Email answer is what Prevent duplicate submissions most often compares on, and it is the address a respondent email notification is sent to. Both are set on the form's Settings tab.
