This tip involves adding an icon (really a .vcf file) to the end of an email that when the recipient double clicks it, will create a new contact with all of the contact fields automatically filled in. The recipient then only has to select save and close to add this contact into to their address book.
The process I used for doing this is shown below:
1. Create a contact for yourself if not done already
2. Fill in as much info in the fields available as you want people to have.
3. Go to Contacts and select your name,
4. From the Action menu, select forward as vCard
5. This brings up a new e-mail note adding an icon to the note that looks like the one below.
6. Add the To:, Overwrite a new title, and add the body and any other attachments to your note as usual.
When the recipient reads your note, and double clicks on the icon, the info will be placed in a new contact card with only the save and close button needing to be selected.
There may be more efficient ways to bring this up in mail, but I did not search them out or try to find them.
Doing this allows any receiver of your notes to easily add you to their contact list.
