Notifications
Tumblr alerts blog owners when you follow them by placing notices on their dashboards. The notice includes your username, a link to your blog and a Follow button that the blog owners can use to reciprocate. If the blog owners use Tumblr’s default settings, they also receive an email notification and possibly a text message. However, the users have the option to disable these supplemental notifications. If the blog owners fail to see any of these notifications, they can also click “Followers” on the dashboard to see a full list of followers, including your username.
