You can send an email resignation letter or a paper resignation letter but is better to resign in person than sending over an email. However, if you wish to send an email resignation letter, you need to ensure that it is very professional as much as a paper letter will be. Make sure you do not include any negative thing about the company or how bad you feel about the company.
