How to cancel Sodalis 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 Sodalis is only as good as the details it quotes.
Put the request in writing
Postbye writes the letter in German from our German template, because Sodalis's address is in Switzerland. It opens with the subject line “Betreff: Kündigungsanfrage – [your name]” and asks Sodalis to end the subscription, stop all further charges and confirm in writing.
Post the letter
Use certified mail for the 3930 Visp address in the next section, so the post office records the delivery. Write down the tracking number.
File the delivery record
Once the letter is delivered, the date on the receipt is the date Sodalis 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 Sodalis cancellation letter goes
For a letter to Sodalis, use Balfrinstrasse 15, kundenservice, 3930 Visp, Switzerland.
Copy the postal code 3930 exactly: it is what routes the letter to Wallis, Switzerland.
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 Sodalis, 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
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
