Special Mail Tags to Configure.
There may be times when you need more information than just the submitter’s input through contact form 7 fields. For example, you may need to know the submitter’s IP address for security reasons. For such purposes, special mail-tags can be very helpful. Unlike other mail-tags, special mail-tags are independent from form fields or the submitter’s input. You can place these special mail-tags anywhere mail-tags are allowed to be used, such as in the message body or other mail fields.
Just select the special mail tags you want to add in your sheet as a header.
