Don't you wish that every person who received a new e-mail account had to agree to follow certain rules to use it? There are certain professional standards expected for e-mail use. Here are some things to keep in mind regarding professional e-mail conduct:
Keep messages brief and to the point.
Use the blind copy and courtesy copy appropriately.
Don't use e-mail as an excuse to avoid personal contact.
Remember that e-mail isn't private.
Be sparing with group e-mail.
Use the subject field to indicate content and purpose.
Don't send chain letters, virus warnings, or junk mail.
Remember that your tone can't be heard in e-mail.
Use a signature that includes contact information.
Summarize long discussions.
