Dynamic Email Subjects for Custom Forms

To help with incoming mail that is sent via a custom form, you can use data that comes through in the form to make up part of the email notification subject.

For each of your form fields, there will be a tag displayed like {{ field_N }} as shown below. 

If you copy and paste this into your subject field, it will be replaced with the users input for that field when the email is sent.

For example, if you entered the following for your subject: 

New message from: {{ field_1 }}

When a user submits your form that might be converted to something like:

New message from: jane.doe@example.com
