Having had 40 years of a profession in which I've had to contact CEOs, CFOs, and Chairman of the Boards, there is one and only way way to do it professionally, courteously, and with certainty that he/she will receive it and read it.
A formal letter, on nice heavy-weight stationary, mailed by regular mail.
Don't worry, executives working at home will have no problem getting mail that was delivered to their offices. They will have a runner bringing it out to the exec at least every other day. They are not going to let it sit there on a desk.
A message in a written letter is virtually permanent when it reaches a company. They can't ignore it and they don't throw it away. It gets filed.
Emails are ephemeral. An executive easily receives 30 or 40 a day. He flips through them rapidly, deleting most of them after he has read them. Sometime, he only reads the first line, judges its importance or not, and trash cans those which he deems unimportant.
A well written letter, with proper grammar and spelling, is far rarer these days. It in and of itself demonstrates care and importance.
Hope this info helps.
