For Kit (ConvertKit) creators
Run your sponsorships on Kit (ConvertKit) — without the spreadsheet.
Email-first platform, no sponsor ops layer. KeelStack is the sponsor operations layer that sits beside Kit (ConvertKit): pipeline, magic-link portal, renewal reminders, invoices, and branded reports. Platform-agnostic, flat $39/mo, no percentage of your revenue.
What Kit (ConvertKit) does well
Kit is built for creators sending email, not for running sponsorship deals. Its automations move subscribers, not sponsor workflows.
What it leaves to you
- Sponsor renewal dates have no home in Kit.
- Asset collection happens over email, then gets re-requested later.
- The same campaign details get retyped into every report.
How KeelStack fits.
It does not replace Kit (ConvertKit). It runs the sponsor side that Kit (ConvertKit) was never built to handle.
Renewal reminders that fire from your own branded address, not a shared one.
A sponsor portal that replaces the “can you resend the logo?” loop.
Reports you build once per campaign and reuse at renewal time.
Move one Kit (ConvertKit) 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.
