This article describes how to find your Tumblr email alias (also: 'email drop box') that was created by Tumblr when you signed up for the service.
The Tumblr email alias can be added to the "receiver email"-field of the "email it" action. By this you can forward text, photo, mp3 and video from Dropbox to Tumblr.
Here is how it works:
- Sign in to Tumblr.
- Click on "Untitled".
- Click on "Blog settings".
- Copy the email alias from the heading "Post by email". This is your Tumblr email alias.
