NatzNash on "Adding name / first name of the recipient on wordpress mail subject"

Hi,

I am using wordpress eMail User 2 plugin ( http://wordpress.org/extend/plugins/emu2-email-users-2/ ) to send an email to my wordpress user.

I want to personalize my mail so the recipients will receive my mail with his / her name at the subject.

The default subject of my mass email looks like: [%BLOG_NAME%] A post of interest: "%POST_TITLE%"

I want to personalize it into: "Hi, [name]! [%BLOG_NAME%] A post of interest: "%POST_TITLE%"

example:
Hi, John! [My Blog] A post of interest: "My newest post!"
Hi, Andy! [My Blog] A post of interest: "My newest post!"

What shortcode or tag I must write for the variable name?

Thank you :)
