Why This Works So Well

When someone's already committed to buying from you, they're in the perfect mindset to hear more from you later. A simple checkbox at checkout can seriously boost your email subscriber numbers without any extra work from your customers.

Step 1: Create Your Mailing List

First, you need somewhere to store these email addresses.

If you're using Squarespace's built-in email marketing:

Go to Marketing > Email Campaigns

Click Lists & Segments

Create a new list for your checkout subscribers

If you're using Mailchimp:

Log into your Mailchimp account

Create a new audience

Give it a clear name like "Checkout Subscribers"

Step 2: Connect Everything in Squarespace

Now to add the checkbox to your checkout:

Go to Commerce > Checkout in your Squarespace admin

Find the Email signup section

Toggle it on

Select your mailing list from the dropdown

Write your checkbox prompt in the "Checkbox label" field

Choose whether the box should be ticked by default

Good checkbox prompts:

"Yes, send me updates about new products and special offers"

"Keep me posted about sales and new arrivals"

"I'd like to receive your newsletter"

Keep it simple and clear about what they're signing up for.

Step 3: Handle Legal Requirements (Especially with Mailchimp)

This bit's important for staying on the right side of the law:

For Mailchimp users: You might need to disable double opt-in for certain countries. In Canada, for example, if someone actively ticks your checkbox, that counts as consent and you don't need them to confirm again via email.

Check Mailchimp's compliance settings and adjust based on where your customers are located.

Top tip: Always test your checkout process after making changes. Place a test order to make sure the checkbox appears and works properly.

What Won't Work

Just so you know the limitations:

Apple Pay checkouts won't show your newsletter option

Digital product checkouts don't display the checkbox either

The feature only works on the standard Squarespace checkout page

Troubleshooting Common Problems

Checkbox not appearing? Check you've selected the right mailing list in your settings and that Email signup is definitely toggled on.

Text not displaying correctly? Go back to Commerce > Checkout > Email signup settings and review your checkbox label text.

Subscribers not appearing in your list? If you're using Mailchimp, check your integration is properly connected and test with a real email address.

Beyond the Checkout Checkbox

While the checkout option is brilliant, don't stop there:

Add newsletter signup blocks to your homepage and product pages

Set up welcome email sequences for new subscribers

Create abandoned cart emails for people who don't complete their purchase

The checkout checkbox is just one piece of building a proper email marketing system.

Quick Answers

Does this work for digital products? No, the newsletter checkbox doesn't appear on digital product checkouts.

Can I change what the checkbox says? Yes, customise the text in Commerce > Checkout > Email signup settings.

What about GDPR and other privacy laws? Make sure your checkbox text is clear about what people are signing up for, and handle double opt-in requirements based on your customer locations.
