Managing form and newsletter storage

When you add a form or newsletter to your site, you'll choose a storage option. This is where you save the information visitors submit so you can review it and take action.

Squarespace doesn’t store form submissions in our system. Instead, we pass the submissions from the form to an external storage option. Depending on the type of form, the available storage options are:

  • An email address - Get an email when a visitor submits a form
  • Google Drive - Collect responses in a Google Sheet
  • MailChimp - Collect responses in a MailChimp subscriber list

If you don't select a storage option, the form won't have a place to send submissions, and visitors won't be able send the form.

In this guide, you’ll learn how to select storage options for a form and some things to keep in mind. If you see an “Add storage to this form” message, follow this guide.

Add storage

At least one storage option is required per form. To add storage:

Then review the steps below for the different types of storage you can add:

Tip: You can add a second storage option as a backup. For example, you can send new form submissions to an email address and connect the form to MailChimp.

Email address

To receive an email every time someone completes your form, use the Email storage option. The default email address is the Administrator’s account email address.

Email address storage is available in:

  • Form Block
  • Cover Page form


Only one email address can connect to each form. To send form submissions to multiple email addresses, use your email provider's automatic forwarding feature. Here are instructions for Gmail.

Change the email address

To send form submissions to a different email address, use the following steps:

  1. In the Storage tab of the form editor, click the X icon next to the address.
  2. Enter a different email address.
  3. Click Connect. The address field will display Sending to when it's successfully connected.
  4. Click Apply to save your changes.

Here’s how this looks in a Form Block:


Email format

Form submission emails have some HTML formatting. Each email includes the following information and can't be customized:

  • Subject Line - Form Submission - Form Name - Subject
  • From -
  • Body - All form fields on separate lines and "Sent via [Your Site Title])”

Reply to a form submission email

If your form includes an email address field, you can reply to the email to respond to the person who submitted the form.

If you experience issues replying directly to the email, your email provider might not support replying directly. Instead, copy the email address and create a new email.

Google Drive

To send completed forms to a Google Sheet, connect to Google Drive. This can be useful for managing large amounts of form submissions in a spreadsheet you can share or export to another system.

Google Drive storage is available in:

  • Cover Page form
  • Form Block
  • Newsletter Block
  • Promotional Pop-Up


When using Google Drive as a storage option, keep the following in mind:

  • You’ll need a Google account. If you don’t have one, create a new account first.
  • The form must connect to a new, empty Google Sheet.
  • You can't use forms with an existing sheet.
  • Forms can’t connect to a specific tab within a sheet.
  • If you disconnect Google Drive then reconnect within the same form, it will reconnect to the correct Google Sheet.
  • Connecting more than 25 forms to a single Google Drive account may cause some forms to disconnect.
  • In Google, you can enable notifications for new form submissions to your Google Sheet.

Connect to Google Drive

To connect a form to Google Drive:

  1. Depending on the form:
    • In the Storage tab, click Google Drive.
    • Under Storage Options, click Google Drive.
  2. Log into your Google account.
  3. Click Accept in the message to allow Squarespace to connect to Google Drive.
  4. Enter a Spreadsheet Name. This creates a new Google Sheet for your form submissions.
  5. Click Apply to save your changes.

Here’s how this looks in a Form Block:


Open the Google Sheet

To view the Google Sheet with your form submissions, open it from Google Drive. For more help with Google Drive, visit Google's overview.

To build an audience for email campaigns, you can connect a form to a new MailChimp subscriber list. This can be useful for newsletter subscription forms and pop-ups.

MailChimp storage is available in:

  • Cover Page form
  • Form Block
  • Newsletter Block
  • Newsletter signup at checkout
  • Promotional Pop-Up


When using MailChimp as a storage option, keep the following in mind:

  • If you don’t have a MailChimp account, sign up from a link in the Form or Newsletter Block editor or directly through MailChimp first.
  • The form must connect to a new, empty MailChimp list.
  • You can't use forms with existing MailChimp lists.
  • To connect multiple forms to one MailChimp list, keep the form fields and settings exactly the same. Any differences can cause MailChimp to drop or reject form submissions.
  • Per MailChimp's policy, forms can't exceed 30 fields.
  • Double opt-in is enabled by default, which requires new subscribers to confirm their subscription via email. If there's a discrepancy between subscribers and form submissions, it probably means some people didn't confirm via email. To learn how to disable double opt-in, visit Using MailChimp with Squarespace.

Connect to MailChimp

To connect a form to a MailChimp account:

  1. Depending on the form:
    • In the Storage tab, click MailChimp.
    • Under Storage Options, click MailChimp.
    • In the Checkout panel, scroll down to Newsletter and click MailChimp.
Tip: If you’re editing a Form or Newsletter Block, click “Don’t have a MailChimp account?” below the MailChimp button to create a new account and automatically connect it to the block.
  1. Log into a MailChimp account.
  2. Select a MailChimp list from the drop-down menu.
  3. Check or uncheck Require Double Opt-In to decide if visitors must confirm their subscription via email. Learn more about double opt-in in Using MailChimp with Squarespace
  4. Click Apply to save your changes.

Here's how this looks in a Form Block:


You can view and manage your newsletter subscribers from your MailChimp account. To learn more, visit MailChimp’s documentation.

Recommended: Send test forms

After connecting to storage, we recommend sending a few test form submissions to see how it works.

If you’re testing a newsletter at checkout, complete a test order and check the option to subscribe to your newsletter.

Tips for connecting multiple forms

If you have more than one form on your site and want them to connect to the same storage, keep these tips in mind.

Email address

You can connect multiple forms to the same email address. To help you see which form a visitor filled out, the subject line includes the form name.

MailChimp and Google Sheets

If possible, we recommend using a different MailChimp list or Google Sheet for each form. If you connect more than one form to the same MailChimp list or Google Sheet, your forms could drop submission data or disconnect from storage.

If you choose to connect multiple forms to one MailChimp list or Google Sheet, each form must be absolutely identical. Any discrepancies between type, name, or arrangement of fields between forms will create errors.

Use the following steps to troubleshoot any issues:

  1. Disconnect the storage option.
  2. If you're using MailChimp, reset the MailChimp connection for each form.
  3. Check each form to confirm all fields are identical.
  4. Reconnect the storage option for each form.
