If you have an email newsletter for your blog delivered by Feedburner, there’s many ways you can personalize and brand your emails. One way is to add your button or logo to your newsletter. It’s actually really easy to do.
1. Login into your Feedburner account.
2. Click the Publicize tab.
3. Click on Email Subscriptions and then from the dropdown menu, select Email Branding.
4. Add the link to your image in Logo URL. If your blog is self-hosted, then this would be the link from your Media Library. You can also have your image hosted on a free service like Photobucket.
5. Click Save to Activate and you are done!
