People visit your site, love your content and want to be notified by email when you post more of that awesome content. So, you install a subscription plugin and configure it with your FeedBurner Email Subscription Feed. When you check it out using a test email you are greeted with an error that says “The feed does not have subscriptions by email enabled.” Huh? I saw this after configuring a plugin.
After some digging in Goggle, “FeedBurner email subscription not working”, “FeedBurner email subscription not enabled”, I realized that I had not told FeedBurner (Google) to allow email subscriptions. Hmmm.
Check this setting:
1. Log into FeedBurner account
2. Click on the Publicize tab
3. Select “Email Subscriptions” under SERVICES
4. Check to see whether the services is active or inactive.
5. Activate if needed.
