Newsletter ad inventory

Everything you sell, in one live list

Every placement you offer, with its own rate, spec and calendar. Set it up once and that same list is what advertisers browse and book from — no rate card to email, no availability to keep restating.

  • A real calendar per placement, so the same slot cannot be sold twice
  • Direct buys and multi-issue packs, priced the way you price them
  • Sold-but-unscheduled inventory surfaced automatically, before it expires

Managed sponsorship sales

Or don’t sell it yourself.

Most newsletter operators do not want to become an ad-sales team, and while the marketplace fills up we are selling inventory by hand anyway. So we will sell yours.

You keep

The part that is yours

  • Writing the newsletter, and the relationship with readers
  • Approval over every sponsor and every piece of creative
  • Your rates — we sell your inventory, we do not discount it

We do

The part nobody enjoys

  • Finding sponsors who already buy in your category
  • The outreach, the follow-up and the negotiation
  • Booking, creative chasing, invoicing and payment
Have us sell it

Tell us about your newsletter and we will set up a short call. Commission on what we book, nothing before that — and the tools and intel stay free either way.

Creative review and approval

Nothing runs until you say so.

Every booking arrives with its creative attached and already checked against the spec you set. Approve it, send it back with a note, or reject it — and keep the whole exchange on the booking instead of buried in your inbox.

  • Dimensions, copy length and file limits enforced at upload
  • Approve, request changes or reject, with the thread kept on the booking
  • Advertisers see the same thread, so good creative clears fast

Sponsorship revenue reporting

Know exactly where revenue stands

Booked revenue, fill rate and average deal size update as bookings move through the pipeline — so the number you quote at the end of the month is the number the system already has.

  • Booked revenue and fill rate, updated as bookings land
  • Invoices generated straight from the booking, with no re-keying
  • Payment status visible to you and the advertiser at the same time

Questions

Newsletter questions, answered

What does it cost to list?

Nothing. Listing inventory is free, Bellwether is free, and creative review is included. We take a commission on bookings made through the marketplace — we get paid when ewe get paid.

Who sets the rates?

You do. You publish your own rate and creative spec per placement, and advertisers book at the price you set. There is no rate-card negotiation round and no repricing by us.

Do I have to accept every booking?

No. Every booking waits for your approval and every piece of creative is reviewed before it runs. You can approve it, request a change with a note, or reject it outright.

What kind of inventory can I list?

Newsletters, for now — that is the only inventory we take at launch. Within a newsletter you can list whatever you sell: the primary slot, secondary placements, classifieds, or a dedicated send, each with its own rate, spec and calendar.

How do payouts work?

A booking becomes an invoice without anyone re-keying it, and payment status sits on the booking so you and the advertiser are looking at the same thing.

Am I locked in?

No. There is no lock-in and no exclusivity. List what you want, keep selling direct alongside the marketplace, and stop whenever you like.

List tonight. Sell in the morning.

Create your brand, add your placements, and let advertisers come to you. Setting up on SponsorSheep takes about five minutes.
