It’s very common that EULAs and other contracts explicitly state that the contractual parties agree that email is a valid means for written notifications. I used to work for a SaaS firm. Every once in awhile the main office would receive a written and signed letters from (primarily) German users when they wanted to terminate their service. (We accepted that after confirmation using an authenticated email address, of course.)
