One nice option that FeedBurner offers is the ability to send out blog updates via email. This is a vital option as there are many more people that understand email but don’t understand feeds.
Just turning on email subscriptions is a good start. Customizing the email that goes out is even better. FeedBurner allows you to edit the subject, fonts, sizes, colors, message and add your own logo. There are really only a few options, but you can better brand your emails with the options available.
To customize your FeedBurner emails, log into your FeedBurner account and click on your feed. Then click on the Publicize tab and then Email Subscriptions in the left column. If this option is not activated, do so now.
