Mailinfo allows you to verify that your email messages have actually been received and notifies you when the message has been read.
The program seamlessly integrates with Outlook and lets you track all or selected emails by simply clicking a button on the toolbar. It inserts a special tracking signature into the message, which also informs the user about the fact that the delivery has been confirmed, so there is not secrecy involved that could be misunderstood by the recipient.

A new mail folder in Outlook enables you to review the status of all your tracked messages and also provides information about when and where the message was received. In addition, Mailinfo displays a real-time alert from the system tray as soon as your message has been read, and also notifies you of emails that appear to be lost, so you can choose to follow up.

The program is very useful to determine that important emails actually get through to the recipients and have not been blocked by spam filters.
