How to cancel Acs by mail
Get your account details together
Acs will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Draft the request
Postbye drafts the request in German, the language of Germany, with “Betreff: Kündigungsanfrage – [your name]” as the subject line. It asks Acs to close the subscription, stop billing and confirm in writing.
Mail it with tracking
Send the letter to the Gmund am Tegernsee mailing address shown below by certified mail. Keep the tracking number safe.
Keep the delivery receipt
It shows the date Acs received your letter. Check your next statement: no Acs charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Acs cancellation letter goes
The mailing address we hold for Acs is Am Talfeld 5, 83703 Gmund am Tegernsee, Germany.
The postcode 83703 belongs to Bayern, Germany, so this is where the envelope is delivered.
The letter greets the reader with “Sehr geehrte Damen und Herren,”; your own details sit under the labels Kontoinhaber, Hinterlegte Rechnungsadresse and Hinterlegte E-Mail-Adresse.

Before you cancel Acs, check these
- 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.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
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
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
