The subject line is the first thing that a person sees when he/she checks his/her e-mail. Make it worthwhile. Best practice is to summarise the overall purpose/objective of the e-mail in the subject line. “Pharmacy Recruiting position” will work. However, “Follow-Up: Pharmacy Recruiting Financial Manager Position” is better. Keep in mind that the person that you are e-mailing may receive dozens of e-mails each day. When short on time, he/she will scan the subject lines of his/her e-mails and answer the ones that seem most important first.
