Please make the FROM: line bolded instead of the subject line. When you receive mail the first thing you want to know is from who.
With E-mail overload one needs to be able to quickly assess each e-mail. We do this by first finding out who is sending you the e-mail, is it your boss or a telemarketer, your Amazon account or a charity, your bank or an offer from Groupon.
Then you look at the subject to know what the e-mail is about.
So, please make the FROM: line bold, not the SUBJECT line.
Thank you for your consideration.
