If you use Feedburner to deliver email newsletters to your subscribers, you might have subscribers who didn’t complete the email verification process which is required when signing up for any newsletter. This happens quite often. Some users are ignorant of the subscription process and that they require to verify their email address. Others might have not even received the verifying email or the mail might have ended up in the spam box.
ProBlogger writes about a great idea of getting these unverified subscribers to confirm their subscription. He suggests writing back to them and letting them know that they can try again if they had some problem with the process. If you aren’t aware, FeedBurner lets you see every email subscriber you have, both verified as well as unverified.
To find this list login to your FeedBurner account, click on the Publicize tab and then click on Email Subscription on the left to expand it. Under Email Subscription click on Subscription Management. Scroll down the page and click on View Subscriber Details to find the list.
You will be surprised when you see how many subscribers are unverified. If you have a large site there might be hundreds of unverified subscribers, and there lies your difficulty. To copy and paste each email address individually is a time consuming process.
To automate this task, Daniel Harrison from PowerDosh.com has written a Greasemonkey script that automatically generates a list of all email subscribers who have not completed the verification process and copies this list to the clipboard. All you have to do is paste them to BCC (so that you don’t reveal the email addresses to others) in the mail compose window and explain to them how they can complete the subscription process. ProBlogger says he got back 40% of these subscribers.
To use it, install GreaseMonkey in Firefox and restart. Then download and install the script. You’ll see it working when you go to Publicize > Email Subscriptions > Subscription Management, on your FeedBurner account. This is likely to work on Opera too (I haven’t tested it).
