What punctuation is used at end of letter?

The most common punctuation used at the end of a letter is a comma, followed by the closing, and then the signature.

Here's an example:

>Sincerely,

>

>[Your Name]

However, there are other options, depending on the formality of the letter and the relationship between the sender and the recipient:

* Formal: A colon (:) can be used instead of a comma.

* Informal: A period (.) can be used instead of a comma.

* Friendly/Informal: You might use a different closing like "Best," "Warmly," or "Cheers," followed by a comma.

It's important to choose punctuation that reflects the tone and formality of your letter.
