What the simple version must still include
Even the briefest letter needs the essentials: a clear statement that you're resigning, your last working day as a date, and a courteous closing. That's it. You don't owe a reason, a recap of your tenure, or an explanation — a single line of thanks is a nice touch but optional. The discipline of keeping it simple is what makes it clean.
When simple is the smart choice
A simple letter fits most ordinary departures: you're leaving on decent terms, there's no drama to manage, and you just need to put your notice on the record. It also helps when emotions are running high — brevity keeps you from saying something you'd take back. State the facts, stay warm, and stop.

How short can a resignation letter be?
Two or three sentences — a statement that you're resigning, your last day, and a brief closing — is enough to be valid and professional.
Do I need to give a reason in a simple resignation?
No. A reason is always optional. A simple letter can state your last day and nothing more.
Is a short resignation letter unprofessional?
Not at all. A clean, courteous, to-the-point letter often reads as more professional than an over-explained one.
