While there is no limit to the number of campaign messages that may be sent by e-mail, the most common infraction of the guidelines is e-mail campaign messages sent without the required "APA Campaigning" at the start of the subject line. In response to member requests, all campaign e-mails must start with "APA Campaigning" at the beginning of the subject line. While candidates can create their own distribution lists for campaign purposes, the only APA-supported list serve that may be used for campaigning is Member-to-Member. Candidates have access to member e-mail addresses in the Membership Directory and Component Directory, but lists of member addresses are not provided by APA.
