By using Mailinfo you can make sure that every email and file you send over the internet is received by your contacts. Sometimes when sending a message from a new email account or to a stranger, spam filters place it in to the trash or unwanted email tray, to avoid this from happening again, this application alerts you when your contact reads your emails. It can work together with Windows Outlook and other applications of the kind. It works by installing a tracker in what you have send that activates when the file is opened. It’s compatible with Windows OS.
