How can I send email with only name of contact (no email attach after the name) and sort by last, first name.?

for this u can send mail by using the Bcc opetion in address Bcc: stands for "blind carbon copy." This is similar to the Cc: feature, except that Bcc: recipients are invisible to all of the other recipients of the message (including other Bcc: recipients). For example, if you send a message To: [email protected] and Bcc: [email protected], then Anuj will see himself as the message's only recipient, while Anuj will see that you have also sent the message to Anuj. The Bcc: field is useful in instances when you don't wish to share your recipients' email addresses with everyone who receives your message
