PrivateMail is a 'speed-dial' for email, ensuring you'll never send a private email to the wrong person again.
If you have someone you tend to send private emails to, use PrivateMail to ensure you never enter the wrong address, and send a potentially embarrassing email to someone else.
Launching PrivateMail brings up an email with the recipient pre-populated. Simply enter your message, and press 'Send'. The email will be placed in your outbox, and your iPhone/iPod touch will send the email as soon as it is able.
To set the email address used by PrivateMail, use the 'Settings' app.
