How to Set a Unique Subject for Form Submissions in Squarespace 7.1
If you’re using Squarespace 7.1 for creating contact forms, requests for quotes, or scheduling requests, a simple enhancement you can take to help you is to set a custom subject line for form submissions. By default, in Squarespace, every form email is sent with some bland subject line like “New Form Submission,” which doesn’t help when you’ve got multiple forms you’re managing or want to stay organized.
In this blog post, I’m going to teach you how to set a custom subject for your Squarespace 7.1 form submissions so you can distinguish between a contact form and a quote request or make it easier to track those emails in your inbox. A personalized subject ensures your email is read and answered sooner and makes your site more professional and branded from a user experience standpoint.
We’ll guide you through, step by step, with the default settings of the Form Block and also share some advanced tips on filtering, automation, and advanced workflows. If you’d like your website to look professional and your emails to be well organized, this guide is for you.
Step-by-Step: How to Create a Unique Subject Line for Form Emails
Step 1: Open Your Form Settings
Go to your page editor in Squarespace.
Hover over your Form Block → Click Edit.
Click the Storage tab (top tabs: Content | Design | Storage).
Under Storage, where you connect your email, you'll see:
Email Settings
Find the field labeled Subject.
Step 2: Set a Custom Static Subject Line
In the Subject field, you can type anything you want.
Examples of good subject lines:
"New Contact Form Submission"
"Quote Request – Website Form"
"Support Ticket from Website"
"New Booking Inquiry"
This customized subject will appear in your email inbox whenever someone submits that specific form!
Example Setup:
| Form Type | Subject: You Should Set |
|---|---|
| Contact Form | "New Contact Form Inquiry" |
| Booking Form | "New Booking Request" |
| Support Form | "Support Ticket Received" |
| Quote Request | "Quote Request - Website Lead" |
This helps you immediately know what type of form came in, without even opening the email!
Step 3: Save and Test
After you set the custom subject:
Click Save on the Form Block
Publish/Save the page
Submit a test form yourself to verify that the subject line is working properly.
You’ll now see your new custom subject line in your inbox!
Pro Tip: Add Page or Form Name for Easy Sorting
If you use multiple forms on your website,
You can include the form/page name inside the subject for better email sorting.
Example Subject:
"Contact Form - Home Page"
"Quote Form - Product Bundles Page"
This way, you know where the submission came from!
Advanced (Optional): Dynamic Subjects (User Input in Subject)
Squarespace alone does NOT allow dynamic subject lines (like including the user's name automatically) natively.
If you need this feature, you can:
| Advanced Option | How |
|---|---|
| Use Zapier | Connect Squarespace forms via Webhook, parse inputs, and customize the subject dynamically |
| Use Third-Party Forms | Embed Typeform, Paperform, or Jotform, which allows custom subjects |
| Use Code Injection | Create a custom HTML form (advanced) |

Quick Summary:
| Step | Action |
|---|---|
| 1 | Edit the Form Block |
| 2 | Go to Storage > Email Settings |
| 3 | Set a custom static Subject Line |
| 4 | Save, test, and manage your inbox professionally! |
Now you control what your form submission emails say in the subject.
Final Thoughts: Take Control of Your Form Submissions
One of the fastest and easiest ways to keep things organized and respond quickly and professionally when someone fills out your contact form in Squarespace 7.1 is to set a unique subject line as one of the form submission settings. When you’re faced with an inbox full of nondescript messages, it’s easy to amass replies without knowing what each message represents, which means you run the risk of leaving high-quality leads stranded!
Whether it’s a contact form, booking request, support request, or quote form, this makes a big difference in the daily process and better communication.
Quick Recap:
Ensure the subject is customized at Form Block > Storage > Email Settings.
Subject: Use concise and clear subjects like “Booking Request from Home Page”.
Test your forms… and make sure your inbox reflects your new configurations

Send emails to different departments based on user selection, either with Zapier or a third-party form
FAQ: Setting Custom Form Submission Subjects in Squarespace 7.1
1. What is the purpose of customizing the subject line of a form submission?
Customizing the subject line helps you instantly identify which form a user filled out (e.g., “Quote Request” vs. “Contact Form”). It streamlines inbox management and reduces the chances of missing or misclassifying important leads.
2. Where can I find the subject line setting in Squarespace 7.1?
Inside any Form Block:
Hover over the block and click Edit
Go to the Storage tab
Under Email Settings, locate the Subject field
Type your desired custom subject and click Save
3. What should I write in the subject line?
Use a clear, action-oriented subject. Good examples:
New Contact Request from Homepage
Booking Inquiry—Events Page
Website Quote Form Submission
This helps distinguish between forms and adds a professional touch to your email communication.
4. Can I use the same subject for all forms?
Technically, yes, but it’s not ideal. Using unique subjects per form helps.
Track user intent
Speed up your response process
Keep communication organized, especially if multiple team members manage the inbox
5. Will the subject line show up in the user’s confirmation email?
No. The subject line set in the Form Block is only visible in the notification email sent to the website owner or recipient, not to the user. If you want to send confirmation emails to users, you’ll need to integrate tools like Zapier, MailerLite, or Squarespace Email Campaigns.
6. Is it possible to include the user’s name or form data in the subject line?
Not with Squarespace’s native tools. Squarespace currently does not support dynamic subject lines (e.g., automatically inserting the user’s name or selected service).
To do this, you’d need to
Use Zapier or Integromat
Pass form data into third-party email tools like Gmail, ConvertKit, or Mailchimp
7. How do I ensure the subject line is working?
After updating:
Click Save on the Form Block
Submit the form yourself as a test
Check the inbox of the connected email—your custom subject should appear exactly as entered
8. Can I include the page name in the subject for better sorting?
Yes! It’s recommended. For example:
Contact Form—Home Page
Request a Quote—Pricing Page
This helps you identify where the form was submitted from, especially helpful for multi-form or multi-service websites.
