Unique Subject
MetroFax has added a new feature that enables you to optionally include each fax’s unique ID in the email subject line. If you use an email client, such as Microsoft Outlook or Google Gmail, that displays your message by conversation or threads, this helps to keep each fax that you receive as a top-level or unique item that isn’t combined with other similar subject faxes.
On the My Dashboard tab, click My Account to open your Account Profile. Under Email Confirmations select the Include FAX ID in Subject check box.
