Who buys this
Newsletter writers who sell sponsor slots and track it all in a messy spreadsheet.
Where to start in Lovable
Paste this into Lovable as the opening prompt. It sets up one screen and one job, which is easier to grow from.
Build a newsletter sponsorship dashboard. The writer lists available issues and ad slots, sponsors book and pay for a slot, and the writer sees a calendar of what is sold versus open plus total revenue. Add a public rate card page sponsors can book from, an invoice per booking, and a reminder to send the sponsor's creative before the issue goes out.

Build order
- The sold-versus-open calendar. One screen answers the writer's daily question: which issues still have open slots to sell. Build that calendar first, everything else supports it.
- A public rate card that books. A shareable page where a sponsor picks a slot and pays removes all the back-and-forth email. That self-serve booking is the whole time saving.
- Chase the creative for them. Sponsors are late with their ad copy constantly. An automatic reminder before each issue saves the writer the awkward chase and keeps issues on time.
Where this usually breaks
- This only helps writers who already sell sponsorships. Do not try to also find them sponsors: that is a marketplace, a far harder product. Stay a tracking and booking tool.
- Pricing ad slots is the writer's job, not yours. Give them the calendar and rate card, but do not promise to optimise their rates.
How it makes money
- Flat monthly per newsletter. Simple and fair for a solo writer. Scales if they run several newsletters.
- Small fee per booking. Ties your revenue to theirs, but keep it low since the writer already gives up a slot's value.
