How to cancel Mymuesli by mail
Find your account details
Have the name and email on the account and, if you have one, an account or customer number to hand. The details in the letter need to match what Mymuesli has on file.
Write the cancellation request
Postbye drafts the request in German, the language of Germany, with “Betreff: Kündigungsanfrage – [your name]” as the subject line. It asks Mymuesli to close the subscription, stop billing and confirm in writing.
Post the letter
Take the letter to the post office and ask for certified delivery to 66127 Saarbrücken. Keep the tracking number it gives you.
Hold on to the receipt
It shows the date Mymuesli received your letter. Check your next statement: no Mymuesli charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Mymuesli cancellation letter goes
Written requests to Mymuesli go to Warndtstraße 115, 66127 Saarbrücken, Germany.
The envelope is going to Saarbrücken in Saarland, Germany, so the postcode 66127 must be on the front.
Your details go in a block headed by Kontoinhaber, Hinterlegte Rechnungsadresse and Hinterlegte E-Mail-Adresse, and the opening line is “Sehr geehrte Damen und Herren,”.

Before you cancel Mymuesli, check these
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
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.
