For Mailchimp creators
Run your sponsorships on Mailchimp — without the spreadsheet.
Email marketing at scale, manuals for sponsor admin. KeelStack is the sponsor operations layer that sits beside Mailchimp: pipeline, magic-link portal, renewal reminders, invoices, and branded reports. Platform-agnostic, flat $39/mo, no percentage of your revenue.
What Mailchimp does well
Mailchimp handles campaigns and audiences. Sponsorship operations — pipeline, assets, invoices, renewals — are not part of the product.
What it leaves to you
- The sponsor pipeline is a separate spreadsheet with no live status.
- Nobody can see which sponsors have and have not sent assets.
- Invoices and renewals are chased manually month after month.
How KeelStack fits.
It does not replace Mailchimp. It runs the sponsor side that Mailchimp was never built to handle.
A Kanban pipeline that shows exactly where every deal stands.
Live asset status per sponsor, updated the moment they upload.
Overdue invoice sweeps and renewal reminders, automated.
Move one Mailchimp sponsor through the full workflow.
Add the sponsor, send the portal link, watch the assets arrive, then send a report. If it doesn't click in 14 days, walk away.
