How do I change my last name from Charles to Blackman-so that it appears whenever my email is sent out.?
You need to change your "From" and that will fix your problem.





Click Options in the upper-right corner of your Yahoo! Mail page.


Under “Management”, click General Preferences.


Right at the top, in the “From name:” box, enter your name how you’d like it to appear in the "From:" line of your outgoing messages. Example: “Sally Tiptoes”.


If you want, you can also adjust the email address to which people send messages when they click “Reply”. If you leave the “Reply to:” field blank, your Yahoo! Mail address is the return address. Specify a different return address by entering it after “Reply to:”.


Click Save to put your new settings into effect.


Note: “From” can’t contain special characters like the "@" symbol. And, the address in “Reply to:” can’t exceed 40 characters.

If you are using the All New Mail then it is a little different. They still are working on the set up.
