Adding a newsletter subscribe option to checkout

You can encourage customers to subscribe to a newsletter at checkout by integrating a MailChimp account with your site. This adds a Join our mailing list checkbox below the email field on your checkout page.

The subscribe option is great way to build your mailing list, increase customer loyalty, and encourage repeat purchases.

Step 1 - Create a list

To start, you'll need to add a new, empty list in MailChimp. This lets MailChimp store subscribers' information and save it specifically for this mailing list.

In your MailChimp account, create a list.

Note: For more help, visit Mailchimp's guide to adding a new list.

Step 2 - Connect your MailChimp account

In the Home Menu, click Settings, and then click Checkout.


Scroll down to Newsletter and click Mailchimp.

Log in using your MailChimp username and password.

Select a subscriber list from the drop-down menu.

Step 3 - Enable or disable automatic opt-ins

By default, customers will automatically opt into your newsletter at checkout. To disable automatic opt-ins, uncheck Enable mailing list opt-in by default to have this unchecked for your customers by default.

Certain merchants may need to uncheck this option to comply with local law and regulations, such as anti-spam regulations. Canadian merchants can learn more by visiting Tips for Canadian merchants.

Note: Squarespace doesn't provide specific advice on laws or requirements applicable to your site or business.

Step 4 - Save

When you're finished, click Save.

Your customers will now see a Join our mailing list checkbox below the email field on the checkout page.


Next steps

There are other ways to grow your MailChimp subscriber list on your site. You can use the Newsletter Block or Form Block to add a subscription form to a page, sidebar, or footer.
