How to cancel Aco Connect by mail
Collect the details you need
Aco Connect 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.
Prepare the letter
Aco Connect 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.
Send the letter by certified mail
Use certified mail for the 34127 Kassel address in the next section, so the post office records the delivery. Write down the tracking number.
Save the tracking record
File the receipt with the letter. A Aco Connect charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Aco Connect cancellation letter goes
Aco Connect lists Angersbachstraße 14, 34127 Kassel, Germany as its mailing address.
The envelope is going to Kassel in Hessen, Germany, so the postcode 34127 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 Aco Connect, 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
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
