While you can use your normal everyday e-mail address for our system, we don't recommend it, for obvious reasons. Mixing darknet activity with your real life activity is NEVER a good idea. Create a new e-mail address somewhere, just for this purpose, use that address exclusively for darknet activity (for example, regularly buying products from us), and forget/delete that address completely, if you think you're done with the Darknet.
