Modern correspondence is quite casual, but when you write a letter in Spanish, your tone and phrasing should match the recipient and occasion. This applies to formal and informal communication in the form of a letter (carta) as well as an email (correo electronico). In the following, we’ll show you how to write a letter in Spanish both formally and informally and introduce you to useful phrases for written communication.

How to address and format a letter in Spanish

Begin your letter with a proper header and place your own address at the top, either in a single line or as a block in the top left corner. Follow with the recipient’s address.

Addressing your recipient

Don’t forget to include a person’s title, degree or position before their name:

• Prof. Noelia Namaste – Professor Noelia Namaste
• Ing. Jorge Pérez – Jorge Pérez, Engineer
• Dr. Manuel Miranda – Doctor Manuel Miranda
• Abg. Juan Tomasi – Juan Tomasi, Attorney

Adding the date

Next is the date, which is a single line aligned to the right:

• Jueves, 2 de abril del 2020 – Thursday April 2nd 2020

Take note of the European date format where the day precedes the month. The first letter of the day is capitalized because it’s the beginning of the line, but the month is written in all lowercase. You can follow the date with a subject line or you can summarise your business in the opening of your letter after the greetings.

How to write a formal letter in Spanish

Opening a formal letter

There are a couple of ways in which you can open a letter in Spanish with a formal greeting:

• Distinguido Señor Rosario: / Distinguida Señora Rosario – Distinguished Mr./Mrs. Rosario
• Estimado Sr. Roberto – Dear Mr. Roberto
• Estimada Sra. Rosita – Dear Mrs./Ms. Rosita
• Estimada Srta. Garrido – Dear Miss Garrido
• Estimado señor / Estimada señora – Dear sir / Dear madam
• Muy señor mío: / Muy señora mía – Dear sir / Dear madam
• Estimados señores – Dear sirs/ madams
• A quien pueda interesar: / A quien corresponda – To whom it may concern
• Don Hector – Dear Hector

Take note to use the personal pronouns usted / ustedes, the formal version of you, to show your respect. Formal Spanish communication can sound over the top or “flowery” to the ears of an English speaker, but it’s normal for natives. When in doubt how to address a lady, use Señora over Señorita to not be disrespectful. The formal greeting is followed by a colon, not a comma as is common in English. 

Closing a formal letter

An official closing to a letter in Spanish is equally formal:

• Le(s) saluda atentamente,  – Yours sincerely,
• Cordialmente, / Atentamente, – Sincerely, / Sincerely yours, / Yours sincerely,
• Saludos cordiales, – Best regards,
• Se despide cordialmente, – Saying goodbye cordially,
• Esperando su respuesta, – Waiting for your reply,
• Quedo a la espera de sus noticias, – Looking forward to hearing from you,
• Muchísimas gracias, – Thank you very much,
• Sin otro particular, lo saludo. – Having nothing further to add, I send my regards.
• Cordialmente, y a la espera de una respuesta, me despido. – Cordially, and awaiting an answer, I send my regards.
• Desde ya, agradezco el recibimiento de mi solicitud y aguardo su respuesta. – I thank you for receiving my request and await your reply.
