"Manners are made up of trivialities of deportment which can be easily learned if one does not happen to know them;" - Emily Post

While Ms. Post's advice about the appropriate dress for a butler in a well-appointed house and the rules of conduct for a debutante are hopelessly outdated, good manners still count. Without a doubt, email is an efficient and cost-effective way to build and maintain relationships, whether with your organization's supporters or with your own nearest and dearest. But those relationships will be stronger and healthier if you heed the do's and don'ts of polite email society - they're simple and apply in equal measure to both groups.

Organizations, too, have been guilty of blasting out messages that most recipients don't care to receive. This kind of behavior is a nuisance. Before hitting the send button, think carefully about whether the message merits the time your recipients will take out of their busy lives to read it.

Look for opportunities to connect with online supporters. Invite your e-advocates to attend a press conference or volunteer at an event. They will appreciate being asked, even if they cannot make it, and those who do show up will be that much more committed to your cause. To ensure a better turnout, ask for RSVPs, thank the signups, and send them a reminder message. Lastly, make sure that it is easy for participants to get to the location (don't you just love it when your friends include a Googlemap link?).
