# Creating a Marketing Opt-in Checkbox

You can create a customer opt-in checkbox for your marketing platforms, including both email and sms marketing.

### Email + SMS Consent <a href="#all" id="all"></a>

When placing a form checkbox on your page, under the Settings for the checkbox, place **marketingOptIn** in the element’s “Name” input.

When a shopper consents to both SMS and Email marketing by enabling the marketingOptin checkbox,  a “Contact by Email” field and a “Contact by SMS” field will be visible in the customer’s record.

### Email Consent Only <a href="#email-only" id="email-only"></a>

When placing a form checkbox on your page, under the Settings for the checkbox, place **emailOptIn** in the element’s “Name” input.
