The 5.1 release lays good groundwork for the incorporation of digital marketing communications for constituent management. Unless I missed it in the release notes, I don't see a way to import a digital campaign effort with unique source code for gift tracking and campaign metrics. Requirement would be to import the email drop that has a CTA and the donors are routed to a donation page with a unique source code. When the gift(s) are imported that carry the source code and identify with that campaign. Potentially, you could create a digital finder id in a similar fashion to Direct mail functionality?
