We’ve added a new merge tag in MailChimp that lets you insert Facebook’s like button in your campaigns: *|FACEBOOK:LIKE|*
The Like button has two functions: 1) it enables users to make connections to your page, and, as we’ve implemented it here, 2) to share content back to their friends on Facebook with one click.
Once you add it to your campaign, the button looks like this:
When a recipient clicks the button, they’ll be taken to your email archive, and will get this message:
For logged-in Facebook users, the button is personalized to highlight friends (within their network) who have also liked the email:
In your campaign stats, you’ll see who pressed the Like button, and how many subsequent (re)Likes they generated.
Note that we only show you who Liked the campaign if they’re on your MailChimp list. If a subscriber Liked your campaign, then 5 of his friends saw it on his wall and liked it too, we do not show you who those 5 friends are. That’d be evil. We just show you the total number (5) of his friends who also liked.
Even cooler, you can send targeted emails to "those who have liked a campaign." Just click on the little Excel icon on the Facebook Activity screen, save the file, then upload it as a new list. I expect that we’ll create a more streamlined process for this in one of the next application upgrades, but for now you’ll have to do it manually.
