What Are Sender Details?
Sender details in Squarespace are what your recipients see in the "From:" line of your emails. Setting these up properly helps your emails avoid spam filters and actually reach your audience.
Why Custom Domain Email Matters
Using a custom domain email (like info@yourcompany.com) instead of Gmail or Yahoo makes a huge difference to your email delivery rates. Major email providers often block or filter emails sent from free addresses because they're commonly used for spam.
Custom domains also look more professional. Would you trust an email from "sarah.designer@gmail.com" or "hello@sarahdesign.co.uk"? The custom domain wins every time.
Pixelhaze Tip: If you're still using a free email for business, upgrading to a custom domain email will improve both your brand credibility and email delivery rates.
Setting Up Your Sender Details
1. Start the Setup
- Go to Email Campaigns in your Squarespace dashboard
- Click on Sender Details, then Add Sender
2. Add Your Information
- Enter the sender name that recipients will see
- Add your custom domain email address (free email services won't work here)
3. Verify Your Email
- Squarespace sends a verification email to the address you entered
- Check your inbox (and spam folder) for this email
- Copy the verification code and paste it back in Squarespace
- Click Next to complete the process
Pixelhaze Tip: Don't skip verification even if Squarespace lets you. Unverified emails have terrible delivery rates.
4. Domain Verification
If you bought your domain through Squarespace, it verifies automatically. If you bought it elsewhere (like Namecheap or GoDaddy), you'll need to complete additional verification steps that Squarespace will walk you through.
Common Questions
Can I use Gmail or Yahoo for sender details?
No, Squarespace doesn't support free email addresses for sender details. You need a custom domain email.
How many sender details can I create?
Up to ten, but you can only use one at a time for sending campaigns.
Can I change the email address later?
No, you can't edit an existing sender detail. You'll need to create a new one and verify it.
What if I don't receive the verification email?
Check your spam folder first. If it's still not there, double-check you've entered the email address correctly.
Quick Definitions
Sender Details: The name and email address that appears in the "From:" line of your emails
Verification: Confirming you own the email address and domain you're using
Custom Domain Email: A professional email address using your own domain name
Spam Filters: Automated systems that block suspicious emails from reaching inboxes
Getting It Right
Setting up sender details properly isn't just a tick-box exercise. It's one of the most important factors in whether your emails actually reach people's inboxes or get filtered into spam.
The few extra minutes you spend setting up a custom domain email and verifying everything properly will pay off in much better delivery rates. Your audience can't engage with emails they never see.
