TechCrunch has taken to discuss syndication of RSS content with e-mail, in response to Fred Wilson's RSS vs Email series. And I'm very grateful for the good words on RssFwd.com in the comments. Thanks folks!!
Michael goes on to write his wishlist for an ideal feed to email service, one of it is "I am in control of the email list; no spamming by the service provider". Hmm, I have a different take, but that's another story.
As for templates,... actually, instead of paying for customisation, how about feeds returning "templated and email-ready" content when the user-agent is a known email-aggregator? Just a thought.
Update: Customized footers are now available. Just let me know if you need customisations.
