Hey Erica! What kind of system is your current giving history stored in right now? It should be possible to sync that information over as a token - we've done something similar with scholarship amounts showing up in tokens, and with careful testing the data seems to be accurate so far.
Hi Erica- just seeing this now so hopefully you've gotten it sorted on your side. There are a few ways to approach depending on desired effect. Some 'quick and dirty', others a bit more involved. Can you share if this is a one-time send where you just need the content to show per user vs a variable that could qualify a user to receive different experiences?
