Audience quality
Built around engaged readers only.

What CrossPub optimizes for
Good matches feel like curation, not traffic exchange.
The system is built around adjacent appetite. You should gain readers who are ready for your publication, not just vaguely aware of your category.
Adjacency over overlap
CrossPub looks for newsletters that feel related enough to convert, but distinct enough to introduce genuine novelty.
Reader trust is the product
Every proposed swap is framed like an editorial recommendation, not a growth hack pasted into a footer.
Approval stays with the writer
You see why a match was suggested, what issue slot it fits, and when to pass without burning goodwill.
