This plug-in adds additional features to Web mail services like HotMail and Yahoo.
It offers full tracking, so you can find out when your e-mail is opened, for how long and whether or not it gets forwarded.
The program also features certified proof of posting, delivery and opening. Aside from digitally certified certificates, you can send self-destructing e-mails or use ensured-delivery messages, both of which guarantee that you will always receive notification about the statuses of your messages.
