If you’ve just had a brief conversation at an event, ask, “Is it all right if I drop you a note?” You can follow up with a question in writing. Also, periodically send your potential mentor or sponsor information that she will find insightful. When you have an accomplishment under your belt, let her know about it.

Once you’ve identified people who can be both mentors and sponsors, you need to make contact. Don’t hesitate to introduce yourself to a potential ally at an event or in the elevator and say you admire her work. If the person is spearheading a committee or drive, volunteer to be on it. You can also request an informational interview. You could say something such as “I’ve heard so much about your work [or latest venture] and would love to know more about it.

If a job opens up that she could “sell” you for, tell her, “You’ve been such a valuable resource for me. I would really appreciate having your help on something. There’s a terrific position open at Company A, and I’m hoping you would be able to advocate on my behalf.” Don’t be shy about also asking a sponsor, “Do you know anyone I could talk to?

Start with a two-line summary of your background, and then say what you’re looking for, being as specific as possible. It could go something like this: “I just graduated with a degree in economics, and I worked at a hospital for my past two summers. I’d love a job at a health-related website. I know you once worked for WebMD, and I’d really welcome a personal introduction.
