How to cancel Simde by mail
Find your account details
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to Simde is only as good as the details it quotes.
Draft the request
Simde is based in Germany, so the letter goes out in German, built from our German template. Subject line: “Betreff: Kündigungsanfrage – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Mail the letter with a receipt
Mail the letter by certified mail to the Maintal address in the next section, and keep the tracking number.
Keep the delivery receipt
It shows the date Simde received your letter. Check your next statement: no Simde charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Simde cancellation letter goes
Simde lists Wilhelm-Röntgen-Straße 1-5, 63477 Maintal, Germany as its mailing address.
The envelope is going to Maintal in Hessen, Germany, so the postcode 63477 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 Simde, 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.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
