Capture your customers' marketing opt-in preferences

When a new customer makes an in-store purchase, it’s important that staff ask whether they’d like to join your database and receive marketing via email and SMS. Permission is required by International Law (including GDPR, TCPA, TCIA & CCPA) and our Terms of Use.

Capturing marketing consent (opt-in) means:

If you already use Marketing or SMS add-ons → you can immediately send campaigns and automations to those opted-in customers.

If you don’t yet use Marketing or SMS add-ons → you’ll be building your list now, so when you decide to upgrade, you’ll have a database ready to go from day one.

⚠️ Important: Opt-in is required
By default, customers are not subscribed to marketing. They must provide explicit consent (opt-in) before they can receive campaigns and automations through Marsello. Capturing their preferences early means you won’t miss out on future opportunities to engage them when you’re ready to start marketing.

Before you get started

Here are some key details to know about customer opt-in for marketing messages:

Collecting SMS & Email Subscribers

To collect mobile numbers for SMS marketing, your staff must ask customers if they wish to receive SMS and/or email marketing from your store.
In the Marsello Chrome extension, the “Accepts Marketing” consent setting applies to both email and SMS. If staff enable this setting, the customer agrees to receive promotional messages through both channels.

Staff Training Requirements

As covered in the SMS Marketing Compliance Introduction and GDPR Introduction, your team will need updated training on how to correctly sign up new customers via Cin7 Omni while ensuring proper consent collection.

We also still encourage you to consult a legal advisor familiar with GDPR, TCPA and TCIA before gathering contacts or sending promotional emails or text messages.

How do customers opt in to marketing through Marsello sign-up forms?

Marsello has two different types of sign-up forms: pop-up and landing page. These form templates include a text disclaimer that informs the customer that by submitting the form, they are opting in to receive both transactional and promotional emails and SMS messages from your store.

Default text disclaimer:

*I agree to receive transactional and promotional emails and text messages (to the email address and phone number provided). Consent is not a condition to purchase. You can opt out or change your email and SMS preferences anytime.

⚠️ Important: If you are using another app for sign-up forms, you need to update your forms to also include such a disclaimer that informs the customer that by submitting the form, they are opting-in to receive both email and SMS marketing from your store.

📝 Note: Customers are always in control of their marketing preferences and can opt-out at any time. All promotional messages sent through Marsello include an unsubscribe link, allowing customers to opt out whenever they choose. Alternatively, customers can request to opt out in-store at checkout or manage their preferences online through the Marsello Customer Portal.
