How do you say PS (post script) in Spanish

Question

My Spanish course says that to add a Post Script to a letter you use P.D.

For example:

At end of letter

Bueno, ahora tengo que salir. Escribeme pronto.

Un fuerte abrazo, Neil

P.D. Te mando varias fotos que he tomado de la zona.

Is this correct? What does P.D. stand for?

Thanks for your help.

Answer 1

You are correct, Neil.

It's P.D. (Posdata).
