How to Fix Your Squarespace Email Deliverability Issues
If your Squarespace emails keep landing in spam folders, you're not alone. Poor email deliverability can kill your marketing efforts before they even start. Here's exactly how to fix it.
TL;DR: Quick Fixes That Actually Work
- Use a custom email address that matches your domain (not Gmail or Yahoo)
- Verify your domain properly in Squarespace
- Only email people who actually signed up
- Write clear, valuable content that people want to read
- Ask subscribers to add you to their contacts
- Track your open rates to spot problems early
Set Up Your Custom Email Properly
Using hello@yourdomain.com instead of yourname@gmail.com makes a massive difference to deliverability. Email providers trust custom domains far more than generic ones.
Here's the setup:
- Buy your domain through Squarespace if you don't have one
- Set up Google Workspace through Squarespace for your custom email
- Add this email to your sender details in Email Campaigns
- Verify your domain (automatic for Squarespace domains, manual for external ones)
If you're using an external domain, you'll need to either transfer it to Squarespace or add DNS verification records. The transfer option is much simpler.
Build Your List the Right Way
Your subscriber list quality matters more than size. A small list of engaged subscribers beats a huge list of people who never asked to hear from you.
Do this:
- Add signup forms to your website and checkout process
- Only email people who specifically opted in
- Make your signup process clear about what they'll receive
Don't do this:
- Buy email lists (they're full of dead addresses and spam traps)
- Add people without permission
- Import lists from other platforms without re-confirming consent
Write Emails People Actually Want
Spam filters are getting smarter, but they still can't tell if your content is genuinely useful. Focus on providing value, not just selling.
Content tips:
- Balance promotional content with helpful information
- Keep your subject lines honest (no "URGENT!!!" nonsense)
- Write like you're talking to a friend, not broadcasting to thousands
- Include your physical address in the footer (it's legally required anyway)
Engagement matters:
- Ask engaged subscribers to add your email to their contacts
- Encourage replies where appropriate
- Remove people who never open your emails after 6 months
Technical Stuff That Helps
Most email clients handle HTML differently. Send emails in both HTML and plain text format (called multipart MIME) so they display properly everywhere. Squarespace handles this automatically, but it's worth knowing about.
Your domain authentication (DKIM and SPF records) also affects deliverability. Squarespace sets these up when you verify your domain properly.
Check Your Performance
Watch your email analytics for warning signs:
- Open rates below 15% suggest deliverability problems
- High bounce rates damage your sender reputation
- Sudden drops in engagement often mean you've hit spam folders
If you're seeing consistent spam issues, clean up your list and review your content strategy.
Common Questions
Q: Can I use my Gmail address for Squarespace emails?
A: You can, but don't. Custom domain emails have much better deliverability and look more professional.
Q: How do I verify an external domain?
A: Either transfer it to Squarespace (easiest) or add the verification records they provide to your DNS settings.
Q: What if my emails are still going to spam?
A: Focus on list hygiene first. Remove inactive subscribers, then review your content and sending frequency.
Key Terms Explained
Spam Filters: Automated systems that decide whether your email reaches the inbox or gets blocked.
Custom Email: An email address using your own domain (hello@yoursite.com) instead of a generic provider.
DKIM: Authentication that proves your emails actually come from your domain.
Hard Bounce: When an email is permanently rejected because the address doesn't exist.
Multipart MIME: Sending emails in both HTML and plain text formats for better compatibility.
Good email deliverability isn't rocket science, but it does require doing the basics properly. Set up your custom email correctly, build your list legitimately, and create content people want to receive. Your inbox placement rates will improve dramatically.
