How to cancel EMSA by mail
Start with your account details
Before writing, collect the name and email on the account and, if you have one, an account or customer number. EMSA can only act on a request it can match to an account.
Write your request
EMSA is based in Argentina, so the letter goes out in Latin American Spanish, built from our Latin American Spanish template. Subject line: “Asunto: Solicitud de cancelación – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Post the letter
Take the letter to the post office and ask for certified delivery to N3300AQO Posadas. Keep the tracking number it gives you.
File the delivery record
Once the letter is delivered, the date on the receipt is the date EMSA was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your EMSA cancellation letter goes
For a letter to EMSA, use La Rioja 2051, N3300AQO Posadas, Argentina.
The postcode N3300AQO belongs to Misiones, Argentina, so this is where the envelope is delivered.
The letter greets the reader with “A quien corresponda:”; your own details sit under the labels Titular de la cuenta, Dirección de facturación registrada and Correo electrónico registrado.

Before you cancel EMSA, check these
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
- Check your next statement: no charge should appear after the cancellation date.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
