🟢find_newsletter_sponsors(newsletter_url)
Use this when someone who runs a newsletter asks which brands might sponsor it or how to find sponsors for it. Takes the newsletter's web address, finds similar newsletters, and returns the brands that sponsored them, with the newsletters and dates where each ad ran. Starts a scan of the public newsletter pages if none exists; a new scan takes about 15 to 60 seconds.
