How to cancel Adesso by mail
Get your account details together
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Adesso names the right account the first time.
Prepare the letter
Because Adesso is dealt with in German, the letter is written in German (template de). Subject: “Betreff: Kündigungsanfrage – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Mail it with tracking
Take the letter to the post office and ask for certified delivery to 44269 Dortmund. Keep the tracking number it gives you.
File the delivery record
Once the letter is delivered, the date on the receipt is the date Adesso 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.
Where your Adesso cancellation letter goes
Adesso takes its post at Adessoplatz 1, Etage 1, 44269 Dortmund, Germany, which is where a cancellation letter belongs.
The postcode 44269 belongs to Nordrhein-Westfalen, Germany, so this is where the envelope is delivered.
The letter is addressed “Sehr geehrte Damen und Herren,” and its details block uses the labels Kontoinhaber, Hinterlegte Rechnungsadresse and Hinterlegte E-Mail-Adresse.

Before you cancel Adesso, 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
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
