How to Add Email Marketing to Your Squarespace Website

By Sean Tinney October 16, 2025

Your Squarespace site showcases your brand beautifully—but are you capturing those visitors? Adding email marketing to your Squarespace site takes just minutes and unlocks one of marketing’s most powerful channels.

Why Add Email Marketing to Squarespace

Squarespace powers nearly 5 million websites worldwide, making it a go-to platform for businesses, creatives, and online stores. But here’s what many Squarespace users don’t realize: without email marketing, you’re watching potential customers disappear forever.

When someone visits your Squarespace site, they’re interested right now. Email lets you continue that conversation long after they’ve closed their browser, nurturing relationships that lead to sales, bookings, and loyal customers.

How to Add Email Marketing to Squarespace

Step 1 – Create Your Form in AWeber

Begin by designing your signup form in your AWeber dashboard. We provide several options including embedded forms, pop-ups, and slide-in forms that appear after visitors scroll down your page.

Focus on what you’ll offer subscribers. The most successful email signup forms clearly communicate value—whether that’s weekly tips, exclusive discounts, or free resources. Skip generic phrases like “Join our newsletter” in favor of specific benefits like “Get our free brand design checklist.”

Customize your form’s appearance to complement your Squarespace site. Match button colors to your brand palette and keep the design clean and minimal—Squarespace users appreciate good design, so your form should reflect that same aesthetic sensibility.

Step 2 – Get Your Embed Code

After finalizing your form design, you’ll need the embed code to add it to Squarespace:

1. Navigate to the “Publish” section in your AWeber form settings
2. Choose “Embed” as your sharing method
3. Copy the complete JavaScript snippet provided

Make sure you copy everything—missing even a bracket will prevent your form from working. Our embed codes are automatically optimized for mobile devices, so subscribers can easily sign up from phones and tablets.

Step 3 – Add to Squarespace

Squarespace makes embedding external forms straightforward through its Code Block feature. Here’s the exact process:

1. Open your page editor in Squarespace
2. Locate the insertion point where you want your form—hover between sections until you see the edit points appear
3. Click the plus icon to add new content
4. Select “Code” from the block options menu
5. Click the code icon (</>) in the block toolbar
6. Paste your complete AWeber embed code in the code field
7. Apply and save your changes

The Code Block functions like any other Squarespace element, so you can reposition it by dragging or adjust its spacing using Squarespace’s built-in controls. This flexibility lets you test different placements to see where your audience engages most.

Important: Code Blocks require a Squarespace Business plan or higher. If you’re on a Personal plan, you’ll either need to upgrade or use Squarespace’s built-in Newsletter Block connected to AWeber through Zapier.

Step 4 – Test Your Form

Never launch a signup form without testing it first. Here’s your testing checklist:

1. Fill out your own form using a real email address you can check
2. Confirm the submission process works smoothly without errors
3. Check AWeber to verify your test contact appeared in the correct list
4. Review the confirmation email if you have double opt-in enabled
5. Test mobile display by viewing on your phone or tablet
6. Try multiple browsers to ensure cross-browser compatibility

Once testing is complete, remove your test email address from your list. This keeps your subscriber count accurate and your list clean for future campaigns.

Best Practices

Strategic placement drives results: Position forms where visitors are most engaged. Homepage hero sections capture immediate interest. Blog post endings work well because readers who finish your content are highly engaged. Footer forms catch people as they scroll through your site.

Be specific about what subscribers get: Vague promises don’t convert. Instead of “Subscribe for updates,” try “Get our monthly design trends report” or “Receive exclusive client booking discounts.” Specificity builds trust and sets clear expectations.

Minimize friction in your forms: Every field you add reduces signups. Start with just email address and first name. You can collect additional information later through welcome series or preference surveys.

Experiment with different formats: Don’t assume one form type will work best. Test embedded forms against slide-ins, try different copy variations, and experiment with placement. Our platform makes it easy to create multiple form versions and track their performance.

Welcome new subscribers immediately: Your first email sets the tone for your relationship. Send a welcome message within minutes of signup that delivers whatever you promised and tells subscribers what to expect from future emails.

Monitor and optimize regularly: Check your form conversion rates monthly. Low performance signals something’s off—maybe your offer isn’t compelling enough, your placement is hidden, or your copy isn’t clear. Keep refining until you find what works.

FAQs

Which Squarespace plan do I need for email forms? Code Blocks work with Business, Commerce Basic, and Commerce Advanced plans. Personal plan users can connect AWeber through Squarespace’s Newsletter Block using Zapier, though this adds an extra tool to your setup.

Can I change the form appearance after embedding? Yes—make changes in AWeber’s form builder and they’ll automatically update everywhere you’ve embedded the form. No need to grab new code or re-embed anything.

Will forms slow down my Squarespace site? No. Email forms load asynchronously in the background, meaning they don’t interfere with your page’s primary content loading. Your site speed stays unaffected.

Can I use different forms on different pages? Absolutely. Create unique forms in AWeber for different purposes—one for your blog, another for your services page, a third for your about page—then embed each using separate Code Blocks. This lets you tailor messaging to specific audiences.

What about privacy laws like GDPR? Our forms include compliance features such as consent checkboxes and privacy policy links. Enable these in your form settings before embedding to ensure compliance with privacy regulations.

How do I remove a form later? Simply delete the Code Block in Squarespace’s editor. The form disappears immediately from your site, though existing subscribers remain in your AWeber account unless you separately remove them.

Can I add forms to Squarespace blog posts? Yes—follow the same process to add a Code Block anywhere in your blog post content. Many successful bloggers place forms at the end of posts to capture engaged readers who finish articles.
