How to send mail on windows (other than MAPI)

Question

When viewing the MSDN MAPI documentation page it says the API is now deprecated. If that's the case, what is the suggested API for sending mail these days?

Edit: Thanks for all the suggestions, the managed route isn't suitable for me as we're using MFC.

If you want to open the message in the user's default MUA, SMAPI is your best choice. If you want to send a message without user input, then the above suggestions are best.
