CrossLetter fills a real gap. In the newsletter space, when publishers collaborate on cross-promotion, it’s surprisingly hard to find other newsletters with genuinely overlapping audiences. And when you can’t find a partner with a relevant audience, cross-promotion quickly becomes pointless. CrossLetter addresses that problem by helping newsletter operators grow for free, by matching them with suitable cross-promotion partners. Review collected by and hosted on G2.com.

The current newsletter pool feels a bit tighter than I expected. Right now, it’s somewhat difficult to find a cross-promotion partner, but I think that as time goes on, the pool will grow and this won’t be an issue anymore, especially since there’s practically no competition for those partners.
