Get Started with Customer Information Collection

Customer information collection tools enable you to expand your marketing reach by letting customers sign up for your newsletter. Email addresses and names shared by customers will be saved in your Customer Directory and can be used with Square Marketing or exported for use with a third-party marketing service.

Customers who sign up for your mailing list will be reflected in the Collected Emails group of your Customer Directory.

Collect Customer Information Online

Customers can submit their contact information via a unique QR code that they can place anywhere.

If collecting information for use with Square Marketing, only send marketing communications to customers who have consented to receive marketing emails from your business. You are responsible for ensuring the customers on your list have given explicit permission to contact them and for compliance with all applicable laws. Review our terms for additional information.

Note: Square’s unique QR code and embedded signup form help you comply with the GDPR’s consent requirements by requesting your customers give explicit permission when providing their email addresses. Please be aware that, if you are uploading customer information via CSV, it is your sole responsibility to ensure that you have permission from your customers to email them.

Subscribe from Square Online

On the Checkout page of your Square Online website, your customers can tick the ‘I want this business to use the data I provided to send me marketing communications until I unsubscribe’ box which will automatically subscribe them to your Customer Directory.

Your customer can visit Square’s Privacy Policy or ask you for more information about your privacy practices.

Note: The customer’s contact information is not visible to any other Square sellers unless they provide it directly to other sellers at checkout.

Set Up Email Collection

You can collect email addresses anywhere with a special QR code for customers to scan. When a customer scans the QR code, they will be taken to an information collection page where they can provide their email address and/or phone number to sign up for marketing communications and enrol in a Loyalty programme.

Download the QR code and create a printable sign for your shop >

To download your QR code from your online Square Dashboard:

  1. Go to Customers > Marketing.

  2. Click Settings.

  3. Under Collection Email Addresses, locate QR Code and click Save. This will export your programme QR code so you can create your own signage.

Note: Square’s QR code helps you comply with the GDPR’s consent requirements.

How do I obtain customer consent for my customer to start receiving email marketing messages?

Your customer’s express consent is required to enable this feature and to ensure that any consents you obtain are valid, you must take the following steps:

The Marketing Subscription toggle will be switched to “Off” by default. Once the customer confirms that they wish to receive marketing, you will need to take the active step of turning the toggle “On,” and then you’ll be prompted to “Confirm” that you have your customer’s express consent. You need to make sure that your customer is agreeing to receive email marketing messages from your business and that these messages may include information about discounts, sales, specials, new offerings and other promotional content. The customer’s engagement activity, including email opens, clicks and voucher usage, will also be tracked to provide you with marketing analytics. You must provide this information to your customer before toggling on the marketing opt-in.

Do I have to let my customer know they can opt out anytime?

Yes, you need to let your customer know that they can opt out at any time. There are two ways your customer can unsubscribe to marketing:

  1. Your customer can unsubscribe via an opt-out link when an email is sent from your business.

  1. You can go to the customer’s profile, click “Edit,” and turn off the toggle - this will opt the customer out of marketing. If a customer’s marketing subscription toggle is “Off,” the customer is opted out of marketing.

What if my customer had previously unsubscribed from email marketing messages from my business? Can I still turn the Marketing Subscription toggle “On” if they provide express consent to receive these messages?

Yes, if your customer provides express consent to receive email marketing messages, their most recent consent will apply and your customer can be subscribed to receive email marketing messages.

When should I send an email marketing campaign after I use this Marketing Subscription toggle?

You can start an email marketing campaign immediately after using this feature. You should also turn on your “Welcome Email” marketing automated campaign in order for your customers to receive an email as soon as they make their first purchase. This will help avoid confusion and enable your customer to opt-out if desired.
