TL;DR: Key Points
• Create and manage mailing lists through Squarespace's Contacts panel
• Add subscribers manually or upload CSV files with proper formatting
• Connect newsletter blocks and forms to automatically collect subscribers
• Understand legal requirements for email marketing compliance
• Monitor and maintain subscriber engagement for better results
Creating Your First Mailing List
Building an email list in Squarespace starts with the Contacts panel. You'll find everything you need under Lists & Segments. Here's the step-by-step process:
- Navigate to the 'Lists & Segments' panel in your Squarespace dashboard
- Click 'Create Mailing List' and give it a clear name
- Add subscribers either manually or by uploading a CSV file
- Connect the list to newsletter blocks and forms on your site
The interface is straightforward, which makes managing multiple lists much easier than juggling spreadsheets.
Adding Subscribers the Right Way
You have two main options for building your list:
Manual entry: Open Lists & Segments, find your list, click 'Add Subscribers', and input their details. Don't forget to toggle the marketing email acceptance switch for each person.
CSV upload: This is faster for bulk imports. Your CSV file needs three columns maximum: email, first name, last name (in that exact order). Keep your filename simple with basic characters only. Special characters or symbols will cause upload failures.
I've seen people struggle with CSV imports because they used fancy characters in filenames or mixed up the column order. Stick to the basics and you'll save yourself headaches.
Connecting Forms to Grow Your List
The real power comes from automatic subscriber collection. You can connect newsletter blocks and promotional pop-ups directly to your mailing lists through their storage settings.
Each form can feed into any of your lists. This means you can create targeted lists for different purposes (weekly newsletter, product updates, event announcements) and direct subscribers to the right place from the start.
Legal Requirements You Can't Ignore
Email marketing laws like GDPR and CAN-SPAM aren't suggestions. You need explicit permission before sending marketing emails to anyone. This means:
- Every subscriber must manually confirm they want marketing emails (that toggle switch isn't optional)
- Keep records of how and when people subscribed
- Make unsubscribing easy
- Be clear about what you're sending and how often
Squarespace handles some compliance features automatically, but the responsibility for legal email marketing sits with you.
Keeping Your List Healthy
A smaller, engaged list beats a massive, unresponsive one every time. Export and review your list regularly. Remove people who haven't opened emails in months or have repeatedly ignored your content.
This isn't just good practice - it improves your deliverability rates and keeps your email metrics honest.
FAQs
Can I export my Squarespace mailing list to another service?
Yes, export as a CSV file and import it into any other email marketing platform.
Is there a subscriber limit in Squarespace?
No limit on subscribers, but your plan caps how many emails you can send monthly.
How do I fix CSV import errors?
Check your filename uses basic characters only, and ensure columns are ordered: email, first name, last name.
Jargon Buster
- Subscriber: Someone who's agreed to receive your marketing emails
- CSV file: A simple data file that uses commas to separate information, making it easy to transfer between platforms
- Confirmation Email: An email that verifies someone wants to receive your messages, helping you stay legally compliant
Building effective mailing lists in Squarespace is more straightforward than most platforms make it. The built-in tools handle the technical side while you focus on creating content people actually want to read. Follow the legal requirements, keep your lists clean, and you'll have a solid foundation for email marketing that actually works.
