🛡️ Essential Rules of Thumb
- Native editorial endorsements from the author outperform standard banner images by 3x.
- Negotiate a bundle of 2 consecutive issues rather than a single one-off drop for repetition.
- Provide a custom discount code matching the newsletter name (e.g. CODE20) to track attribution.
