what do you usually sell to your email list?

trying to find a good product to sell to my email list.
if you have a list of these email where most of them are interested in SEO, what would you sell to them?

I would look at clickbank for seo products.

If I had a list of people who were interested in SEO, I would try to market something that falls under that category, such as some SEO service.

I would sell them Cialis and Enlargement Pills...thats what I have been getting after subscribing to few IMers...lol...

jokes aside, sell them SEO related products..like SEOMoz membership, SEOBook membership, SEOPressor plugin, Linkbuilding tools like SENuke, BookmarkingDemon, UBot, UAW.. also ebooks on linkbuilding, list building, social media etc..

but be soft in pitching..

I would definitely offer them a SEOmoz, Majestic SEO, or maybe a SEM Rush or Spyfu membership.
