If you don’t already have a subscription option on your blog it is real easy to do it using Feedburner.
The cool thing about placing a subscription option on your blog is that everyone who enters their email address will automatically get notified in their emails. This is real easy to do with Feedburner.
First you need to sign in with Feedburner. You will need a google account. A gmail email will work.
When in Feedburner visit the Tab that says Publicize.
