For anyone following this request, I want to make sure you are aware that Give Lively recently launched a new integration with Zapier, and you may be able to leverage it to automate activities in Mailchimp when new donations come in or are updated. I can't speak definitively as to whether it would cover this specific request, but it should at least get you closer, or save some of the manual effort.

For more information, please see our helpful guide here: https://www.givelively.org/resources/get-started-with-give-livelys-zapier-integration

And Zapier's listing page here: https://zapier.com/apps/give-lively/integrations

Lastly, we are actively soliciting feedback on the integration, so please share your thoughts if you give it a try: https://forms.gle/TRZCiAEmgeUDidxn9
