You go to Tumblr, enter an email address and password, and you're good to go!
Any email address that you can prove you have ownership of (by clicking a confirmation link sent during registration) counts as a valid email address.
valid e-mail address means it has to be real and have: (your e-mail address here)@(website here).(ending here) To makesure it is an valid email address, you can go to http://www.fraudlabs.com/demomailboxvalidator.aspx to validate your email address.
send them a message at support@tumblr.com and then give them the url and password
no it means an active email
Because whoever programmed "it" wants a valid email address.
A valid email is an address at which you can be contacted, one that works. Most people have more than one email address so you put the address that is the most appropriate for the use intended.
Go to your email and you will receive an email from tumblr and their will be a link for you to click. Click it ofcourse and your TUMBLR account will be verified.
Maybe becasue it is not a valid address.
