A resignation is an official document that an employee has to submit to an organization announcing his decision to leave the company.

Usually, a resignation is given in a written format, after which you serve the notice period as set under the company's rules. However, it is not always necessary to hand over a hard copy of your resignation letter to your supervisor, you can also opt for a resignation email. It is always better to inform your supervisor before hand in person or on phone that you are leaving the organization for better prospects or for personal reasons.
Nevertheless, there are not much differences between a resignation letter and a resignation email. Though the medium through which they are sent is different, the way both have to be written and formatted remains the same. Follow up with HR deptt for the acceptance and ensure timely F&F statement is prepared.
