Send mail to all contacts

Dear friends,
In my file there is a macro to send mail on birthday. Now I want to modify it to send a mail to each contact after running the macro. I want to remove the date condition from this code and send the mail to all the persons in the file. There are about thousands of contacts in my directory.

Please modify it as per my requirement.

Thanking you in anticipation.

Sincerely,

Mukesh
