Darren has a great tip in his post about how to increase RSS subscribers.
He suggests following up with those who have subscribed via email to your feed but who have not verified their subscription.
This is excellent advice for those who have any kind of email subscription database. With the opt-in requirements for email newsletters now in place by all respected email companies, I’ve noticed that a certian percentage who sign up for my email newsletters don’t end up verifying it for whatever reason.
Darren said on his Digital Photography School list he had around 800 unverified subscribers.
Wow. Now if I had THAT many sitting there unverified I’d definitely follow up with them.
