Email Etiquette

An effective Subject line is paramount. A good Subject line helps you and your message recipients view, file, search, and prioritize messages efficiently. I hate having an inbox full of messages with a Subject line starting with URGENT or FYI. Subjects should state exactly what the message is about and nothing more—most recipients can prioritize messages for themselves.

Be Succinct. Try to limit message text to one screen (this varies by client and resolution, of course) so the reader can quickly peruse the message for highlights and main points. Also, stay on topic and avoid long dialogs or discussions via email.

Use Reply All with caution. In some situations, this option is necessary because all recipients need your response. However, a Reply All with the message body "Thanks" probably doesn't need to go to everyone. Closely related to Reply All is the distribution list (DL). Make sure you use DLs with care, and when you see that a large DL has been used, ask yourself whether everyone needs your response before you click the Reply All button.

Limit the use and size of attachments. My pet peeve is dialing in via a 56K RAS connection, replicating mail, and finding that some bloke has sent me a 20MB PowerPoint presentation that I don't even need. Attachments aren't evil by nature—you just need to use them with care. When you add an attachment to a message, consider whether there is an alternative. For example, can you put the attachment on a server and provide a URL (http://server/file) or UNC (\servershare) instead?

Use Signatures—but for heaven's sake don't use the 10MB GIF file of your company logo.

Establish email time. Email time is like naptime in kindergarten. Set aside regular periods during the day when you can read and respond to your email traffic.

Organize your inbox. Create subfolders and organize your email into these folders. You can also use a personal store (.pst file) with Outlook, but be aware of its caveats (backup, size, items)

Use archiving and delete unneeded messages, replies, and acknowledgments. Manage your deleted items folder by cleaning it out manually or simply deleting all items when you exit.

Use Inbox rules sparingly. Rules contribute to email mayhem and create unnecessary overhead on the client and server. If you can get away with it, don't use Inbox rules at all.

Don't oversubscribe. We're all tempted to subscribe to mailing lists and email newsletters that interest us. Make sure that you subscribe to only those that you really have the time to read or are interested in. You might want to set up a public folder and subscribe it to the list instead of having every user subscribe individually. Of course, Exchange & Outlook UPDATE is the exception—everyone in the known universe should subscribe to it.
