The Consent element is how you let visitors choose which Subscriptions to opt in to. Instead of a single blanket "I agree to receive communications" checkbox, the Consent element gives visitors a proper picker — one Subscription per option, selected on their own terms.

It's the right choice when you run more than one Subscription (different newsletters, different product lines, different frequencies) and want to respect the visitor's preference from the very first interaction. Profiles who actively choose their subscriptions engage more and unsubscribe less.

You can request consent for email or SMS communications with either the Consent element or the Terms and Conditions element.

When using the Consent element, keep these things in mind:

Add a Label name to the Consent element to enhance accessibility. The label helps screen readers understand what the element is asking about as a whole — useful context before the visitor moves through the list of Subscription options.
​

A good label describes the question — for example, "Choose your newsletter subscriptions" or "What would you like to hear about?" — while the individual checkbox or dropdown options are the specific choices.
​

In the Mapping section on the right, expand the Subscription dropdown menu. Select a Subscription for each option in the Consent field.

For example, if you have a Folder for your weekly newsletter, you might have a Subscription for women's clothing, another for men's clothing, and one for home accessories. Some visitors might want to sign up for only one; others might want all of them.

If you can see the channel option, remember to pick either Email or SMS as the communication channel for gathering consent. The channel determines how Profiles can be contacted once they opt in.

Double opt-in keeps Audience quality high. Once a visitor provides their email consent, they receive an email asking them to confirm their Subscription. This way you avoid collecting invalid email addresses and keep your engagement rates healthier.

Before you can enable Double opt-in for your Form, you must complete the Double opt-in settings. If you see a message telling you to complete settings, head over to Account settings to configure Double opt-in. Learn more.

Note also that double opt-in must be activated at the Section level by an Admin before it works on any Form in that Section.

Tick Enable Double opt-in to send a confirmation email to Profiles who sign up via your Form.

If you leave this option unticked, the consent for all Profiles who opt in via this Form will be automatically confirmed.

Until visitors have confirmed their Subscription, their Profile will show their email channel consent as Pending. Profiles with a Pending opt-in consent type will not receive any sendings until they confirm their subscription.

In Segment builder, create a segment using the Subscription property and select state Pending Opt in. Calculate or Show profiles to find out how many you have.

This is exactly the protection double opt-in is meant to give — but it also means that forgotten confirmation emails cost you subscribers. Design the confirmation email and the confirmation destination Page carefully. See Form: Action.

Choose whether the Consent element should display as a Checkbox or a Dropdown.

To learn more about the two styles, see the Dropdown element or the Checkbox element — the styling options are the same.

Set colour for Border, Fill and Check. Use the colour picker, RGB or hex code. To make it transparent, click the X icon next to the colour code — the preview will show a white circle crossed with a red line.

For a new subscriber, show two or three Subscription options — e.g. "Weekly newsletter", "Product news", "Events & webinars". Visitors pick the ones they want. Each choice becomes a separate Subscription they can manage independently, and each unlocks a focused nurturing flow in Marketing Automation.

This outperforms a single generic "Subscribe" option because it sets the right expectations from day one.

The Consent element is the heart of a good preference centre. List every Subscription a Profile could be part of, and let them actively choose which to keep. For existing Profiles, combine with Allow Profile overwriting in Form: Action so updates stick.

Preference centres built this way reduce blanket unsubscribes — a Profile who'd otherwise unsubscribe often just wants fewer emails, not zero.

If your organisation has multiple brands or product lines under one Section, a Consent element lets visitors opt in to the brands that interest them without forcing them to accept everything. The Profile joins just the right Subscriptions, and each brand can send without affecting the other brands' engagement metrics.

A Consent element with "Weekly updates" / "Monthly updates" / "Big news only" as Subscription options lets loyal Profiles control their own cadence. Respecting frequency choice is one of the strongest loyalty signals a brand can send.

Causes to check.

Cause. Double opt-in settings haven't been completed in Account settings, or double opt-in isn't activated at the Section level.
​

Fix. An Admin needs to complete the settings. See Double opt-in.

​

Cause. By design. Only one Consent element is allowed per Form.

Fix. Put all your Subscription options inside the single Consent element. If you have two genuinely distinct consent moments (for example, newsletter vs. terms of service), use the Consent element for the choice and the Terms & Conditions element for the single-purpose agreement.

​

Cause. The Subscriptions live in a different Section.

Fix. Build the Form in the Section where those Subscriptions live, or create the Subscriptions in the Form's Section.
