To emaul a person is to send them a gazillion emails, even though all that could get done in one 3 minute phone call. It could also happen when someone just has to forward every stupid stinking chain letter "Please send this for good luck" "Somebody loves you" "Bill Gates will send you a check! I know it's true, My brother's cousin's roomate's ex boyfreind's mother-in-law's nephew works for Microsoft" Dreck.
Since Maria didn't have IM at work, she and Jen were emauling each other all day long.
If somebody emauls me one more time about my relatives that crashed in Nigeria, I'm gonna have to deep six them.
