Give it your newsletter's web address and it finds similar newsletters and lists the brands that sponsored them, with the newsletter and date of each ad, so you know who already buys newsletter ads in your space. You can also ask which brands sponsor newsletters overall or in a topic such as AI, finance or marketing, and what newsletters charge for the main sponsor slot of one issue at your list size, from prices newsletters publish on their own advertise pages.\n\nResults name brands and where their ads ran. They do not include people's names or email addresses. A scan reads only public pages; a newsletter that cannot be read from its website, or that already has a Book a Sponsor account, is not scanned here. Political and adult newsletters are left out.",
