Message tags take the uncertainty out of email by allowing you to deliver messages, instead of just sending them. MSGTAG is a new desktop application that tells you when your emails have been received and opened.
It works alongside your existing mail program and works on almost all popular email clients, sending you an email the moment your message is viewed — just to let you know.
MSGTAG quite simply lets you know they've got the message. And it's free! Put an end to wondering if you emails have been received because with MsgTag, you´ll know!
