The -tofriendly parameter adds personalization to your email. Instead of the recipient's email address appearing in the "To:" field of the email message header, a friendly name appears. For example "To:" would show "John Doe" instead of "firstname.lastname@example.org".
The "To:" field in an email client can display the email address (e.g. email@example.com), an equivalent "friendly" name (e.g. "Bob Smith"), or both. Client behavior varies as to what exactly is displayed. Many clients display e.g.:
To: "<friendly>" <email address>
In others, if the "Friendly" address is present, the "normal" email address is not displayed.
Other Parameters Required:
-tofriendly "<friendly recipient name>"
Example (cut-and-paste right into your batch file):
NetMailBot -tofriendly "John Doe" -to firstname.lastname@example.org -from email@example.com -server mail.domain.com -subject "test"
