How to cancel Aetkasmart by mail
Note your account details
Aetkasmart 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.
Set out the request
The request is prepared in German (template de), under the subject line “Betreff: Kündigungsanfrage – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Post it with proof of delivery
Send the letter to the München mailing address shown below by certified mail. Keep the tracking number safe.
Hold on to the receipt
Once the letter is delivered, the date on the receipt is the date Aetkasmart 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.

Before you cancel Aetkasmart, check these
- 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.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.
