List-building is everything.  It’s the beating heart of your organizing, branding, fundraising, everything strategy online.

Co-registration is on the tip of many commerical marketers’ lips all of a sudden.  It’s been around a while but may be headed toward some type of tipping point.

Like the myYahoo folks who use RSS every day and don’t realize it, you may already be a co-registration customer.  That’s what Care2 does.

DMNews suggests that the commercial rate for new email addresses ranges from 25 cents to $2, which by the way makes Care2 a premium brew.  I’m going to go out on a limb here and say there is not a single organization I’ve ever worked with that feels they spent too much time and effort on list-building.  Have you spent enough?
