This might seem obvious, but you'll be surprised how many people
just scan the subject line, and delete the email if it doesn't seem
relevant to them. Put a call to action into it. "5 things I need
you to do tomorrow" is much better than "Things". It also makes
searching for mail much easier. Consider adding the following:
- [Time
Sensitive]
- [Action
Item]
- [NNTR, NRN or
FYI]: put one of these 3 at the end of the subject
line (this means No Need to Reply, No Reply Necessary or For Your
Information), it will make the recipient feel good knowing they can
just enjoy reading your email and not have to do anything.
- [EOM]:
If you can fit the entire message into the subject line, put EOM at
the end (End of Message) and they won't have to open the
message.
