There is no demo of Email Balancer because it operates on form actions. Email Balancer makes the [email] action able to distribute emails in a rotating sequence. For example you have the following email action:

[email to="contact@bbforms.com"]CONTENT[/email]

Then, you want to distribute email sending with other email addresses like this:

[email to="contact@bbforms.com" balance="1@bbforms.com, 2@bbforms.com, 3@bbforms.com"]CONTENT[/email]

Setting the action like this will:

1. Always sends the email to the email defined in to attribute.
2. On every form submission, will distribute emails defined in balance attribute in a rotating sequence:
   1. Form submitted, emails to Email 1.
   2. Form submitted again, then emails to Email 2.
   3. Form submitted again, then emails to Email 3.
   4. Afterwards cycles back to Email 1, continuing the process repeatedly.

This ensures that emails are delivered evenly across all configured addresses.
