Just change the subject lines. Few things are more annoying than 

receiving an important e-mail message that carries a clueless 

subject like “hey” (or worse, an empty subject line). A more 

meaningful subject line improves your search index 

and makes your e-mail thread more valuable in general. In Outlook, 

open the message(this tactic doesn’t work with just a preview), 

select the subject line, and type over it with the more-useful text

you want.
