I know this will not be an easy task, but a friend informed me that he used a service that emailed everyone who ever emailed him at a college email address to notify them of his new email address. I have searched online for days and cannot find what he was talking about.
My original account is with Comcast, and contacts are not automatically saved (unlike Gmail which saves every contact that I email to "other" to await proper filing). Anyone have some ideas? Obviously I could send a message to everyone in my contacts - but I only have about 20 saved.
