Frequently asked questions

When should I raise my sponsorship rates?

As your audience and engagement grow, update your rates to match the increased value, rather than leaving them frozen. Deliberate, periodic increases keep your pricing aligned with what the placement now delivers.

How do I add more ad inventory without losing readers?

Add placements gradually and keep them relevant and clearly marked, so the newsletter stays enjoyable. Overloading it with ads erodes the reader trust that makes your inventory worth buying in the first place.
