David Sklar suggest that RSS could be the “Ultimate Opt-In Solution” over on the O’Reilly Developer Weblogs. I have to say, he has a good point.

If I could just add a personalized feed into my feed reader, we (me and the company) would both be better off: I can trust the source of the message, so I don’t need to do any spam filtering. I can retrieve the feed over an SSL connection, so it’s a feasible way to provide sensitive data like a bank statement or monthly bill. The company I’m getting the feed from knows when my feed is retrieved so it has some rough metrics for determining that I’ve actually received the data in the feed.

Doesn’t this sound like a good idea? As spam-filters become ever-more aggressive, it’s becoming increasingly difficult for commercial email to make it through to the desktop. However, if the corporate were to supply password-protected, SSL-encrypted RSS feeds to its customers they would be almost guaranteed to achieve delivery.

Sounds like a win-win for both parties.
