This e-mail is for older workers to apply for high-tech jobs and other positions that are more frequently held by younger people.
You're probably accustomed to receiving e-mails from persons half my age. And it's true that much of my generation looks at the Internet as something from a science fiction movie. However, for me nothing could be further from the truth. In fact, my background as a <technical job> is part of the reason I've embraced the Net wholeheartedly. It's also a demonstration of why I think I would be the ideal candidate for your available <available position> position. I bring years of <your field of expertise> skill to any company, and I've proven that my abilities can maximize value and profit potential for my employer.
I would like to speak with you further about the available position. Now that I've blown my own horn, I'll simply thank you for your time. My resume is attached; if you have trouble reading it let me know and I'll send it in the mail. Thank you again, and I look forward to hearing from you.
