can people search you on tumblr?

[Lollipop]

I was wondering if there is an option to search people using their email on tumblr. For example, my friends searching me on tumblr using my email address. Is that possible? And if so, is there a way to turn that option off?
Just wondering cuz I don't want my friends following me on tumblr.

I dont think thats an option. you should try it your self just in case.
i think your email is private.
