"Now Dasher! Now Dancer!
Now Prancer and Vixen!
On Comet! On Cupid!
On Donner and Blitzen!"

It's Christmas Eve, and Santa is having trouble with his computer. It's too late to have it repaired, so he has to work around the problem. He is able to send the following email:

To Bobby, Adam, and Danny,
     Mrs. Claus and I  know you all act as good boys, and I look forward to my visit with your family this Christmas. I will study your Christmas lists and try to bring a toy, book, or gift of clothing, which will bring you joy.
     I was fond of that snack you put out last Christmas. So was Rudolph. Many thanks from both of us. Wish us good flying conditions, with no rain or fog (although snow is all right).

                                                             Happy holidays,
                                                                    Santa Claus

Santa sent this message to 3boys@aol.com. He then asked Rudolph to send a message to each of the eight reindeer, directing them to report to work. Their email addresses are Dasher@aol.com, Dancer @aol.com, and so forth. But then Santa realized that because of his computer problem, only one reindeer would receive the message. Which reindeer?

Answer:

Cupid is the only reindeer that will receive the message, because Santa's computer keyboard's letter E is broken. In his email to Bobby, Adam, and Danny, Santa managed to avoid using any E's.

NO E MAIL? 

Note from JA: The name of the seventh reindeer is in dispute. Is it DONNER or DONDER? The original poem, "The Night Before Christmas" by Clement Moore says DONDER, which I personally prefer. I used DONNER in this puzzle because that is how Mr. Senner wrote it.
