Last week, we started talking about using the Subject line when sending emails. Here are a few more rules to consider.
Talk About One Subject per Email Message Only
Help make the world less confusing. Try to talk about one subject per message only. For another subject, start a new email.
Keep Your Subjects Lines Short, but meaningful
Make sure the recipients can read all of your Subject line (40 to 60 characters MAX).
Repeat Important Subject Information in the Body
The Subject line of your email is important, but you shouldn’t rely on it being read or paid attention.
Change a Thread’s Subject When the Topic Changes
Change occurs to an email thread’s topic, and then the email’s Subject should change, too.
