How to cancel Sudts by mail
Note 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 Sudts is only as good as the details it quotes.
Write your request
Postbye writes the letter in French from our French template, because Sudts's address is in France. It opens with the subject line “Objet : Demande d'annulation – [your name]” and asks Sudts to end the subscription, stop all further charges and confirm in writing.
Post it with proof of delivery
Post it by certified mail to Sudts in Montpellier, France, using the exact address below, and note the tracking number.
Keep proof the letter arrived
File the receipt with the letter. A Sudts 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 Sudts cancellation letter goes
Sudts can be reached by post at Rue Léon Blum 494, 34000 Montpellier, France.
The envelope is going to Montpellier in Occitanie, France, so the postcode 34000 must be on the front.
Inside, the salutation reads “À qui de droit,”, followed by your details under Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

Before you cancel Sudts, 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
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
