Abstract: Systems and methods are provided for generating referral emails. Particularly, referral emails are generated as part of a campaign initiated by a member of an online community. The referral emails are customized based on both information about the potential member and the referring member. An email campaign may include a number of emails that change over time as a result of particular events being triggered. Links for particular assets, such as privileged web content, may be included in emails. Such links may be selectively chosen from an asset database. Such a selection may be chosen, for example, based on the stage of the referral/marketing campaign, information about the potential member, information about the referring member, and the contents of the assignment database.
