I built an open source tool for tagging Mailchimp contacts from a names-only list
I work in a membership based organization and I'm always getting lists from other departments without emails attached. It was a huge pain point for me to manually tag contacts one-by-one in Mailchimp, so I built this simple tool. I figured I couldn't be the only one out there using Mailchimp and running into this issue, so I wanted to share.

Banana-Tagger is a command-line tool (with an optional GUI) for tagging Mailchimp audience members from a CSV that has names only, no email addresses.
Mailchimp's own CSV import can tag contacts, but only by matching on email. This tool exists for the opposite case: you have a list of full names from somewhere that was never tied to Mailchimp in the first place (an event roster, a sign-in sheet, a waitlist a front desk kept by hand) and you need those people tagged in your existing audience without typing each name into search one at a time.
If your source list already has emails, you don't need this, use Mailchimp's native import instead. This tool is specifically for when all you have is a name.
