Inviting Delegates

What is the best way to invite these Delegates to the Conference?

Should you or one of your colleagues approach them personally? This might be a suitable strategy if you know them well and want the opportunity to chat informally, answer questions and so on. It may not be appropriate when dealing with people who might not welcome an informal approach and could even be annoyed or offended by it.

Telephone invitations have the advantage of being informal and allowing instant, two-way communication. The disadvantages are that you might call at an inconvenient moment or find it hard to judge the person you speak to by their voice.

Should you send a letter of invitation? This might be most appropriate when you wish to incorporate persuasive, back up documents but inappropriate if you are not sure how to phrase an invitation.

You could issue invitations via a third party. A business associate might be better place to invite delegates on your behalf if he or she knows them well and understands what makes them tick. Will he or she approach them properly, though, and say what you want them to?
