Mailchimp vs Squarespace

The overlap here is email. Squarespace is a website builder, and Squarespace Email Campaigns is its add-on for newsletters and announcements. Mailchimp is a dedicated email marketing tool. If you run a Squarespace site and want to send a monthly newsletter or a sale announcement with your site's look and products, Email Campaigns is the easy choice. If email is a growth channel, with welcome series, segments and testing, pick Mailchimp. Many Squarespace owners use both: Squarespace for the site, Mailchimp for the list.

Pick Mailchimp if

• You need automated flows such as welcome series and abandoned-cart emails.
• You want deeper segmentation, A/B testing and reporting.
• Your site isn't on Squarespace, or might move.
• You want to start on a free plan.

Pick Squarespace if

• Your website or store already runs on Squarespace.
• You want emails that pull in your site's branding, blog posts and products.
• Your list is large but you send rarely, since Email Campaigns doesn't charge by contacts.
• You'd rather pay one vendor for the site and the email.

How they differ

Pricing. As of November 2026, Mailchimp's Free plan covers up to 250 contacts and 500 sends a month. Paid plans are billed monthly and scale with contacts: for up to 500 contacts, Essentials starts at $13 a month and Standard at $20. Squarespace Email Campaigns is a separate subscription on top of a site plan. Its tiers are priced by monthly email sends, from 500 up to 500,000 a month, with unlimited contacts on every plan and up to 30% off for paying annually. Without a plan you can send three trial campaigns. Site plans start with Basic at $19/month billed annually or $25 monthly. Check squarespace.com/email-marketing for current Email Campaigns prices.

Core strength. Mailchimp's edge is depth: automation, segments, testing and integrations with most ecommerce and CRM tools. Squarespace's edge is convenience. Your site's styles, products and blog posts drop into emails, and subscribers from your site's forms land in the same account.

Where each falls short. Mailchimp's contact-based pricing climbs fast as your list grows, even if you send rarely. Squarespace Email Campaigns has basic automation and reporting, and it only makes sense if your site is on Squarespace.
