Title: Problem:<p>1.)  Hard for Content Newsletters to Find advertisers and sponsors.<p>2.)  Very difficult for startups who want to advertise in newsletters to find similar newsletters to advertise in.  (no central location - have to find advertise area on website for each newsletter or email publisher directly for smaller newsletters)<p>This isn't just something that's new for newsletters.  I believe this was inherited from direct mail from magazines and publishers.  I remember pursuing a startup idea in high school, looking for ways to reach out to highly targeted magazines, and being pointed to a directory in the library.  And even the library didn't have that directory.<p>My Solution:  BuySellAds.com type of website for content newsletter publishers.<p>My Minimal Test:<p>Advermin.com - Performable Landing page to see if there's interest in this.  Landing page hooks up to mailchimp.  For first few weeks, I'll send advertising opportunities from friends who own content newsletters - see if there's interest and if we can pick up steam.<p>Finding if publishers are interested by using howtosubscribe.com to find newsletter publishers.<p>My Concerns: 
(1) Too small of a market.  Some of the data from EasyUnsubscriber.com shows me that most email newsletters are from newsletters that are selling a product or service or are extremely interested in driving traffic to their blog.<p>(2) The larger newsletters (highest value customers)  probably don't need someone to find opportunities because they're popular enough to attract advertisers directly.<p>Target Newsletters include content newsletters like HackerNewsletter and Startup Digest.<p>Final Plea:  Please poke holes in this.  Tear me apart.  Spit on my ideas.  I want to save time and focus full attention on easyunsubscriber.com if this idea isn't worth pursuing.  All input appreciated.
