How to cancel Boutique So by mail
Gather your account details
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Boutique So names the right account the first time.
Draft the request
The request is prepared in French (template fr), under the subject line “Objet : Demande d'annulation – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Mail it with tracking
Use certified mail for the 59718 Lille address in the next section, so the post office records the delivery. Write down the tracking number.
File the delivery record
Delivery confirmation is your evidence that Boutique So was asked. Watch the next statement or two for any further Boutique So charge.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Boutique So cancellation letter goes
Boutique So takes its post at CS 90006, 59718 Lille, France, which is where a cancellation letter belongs.
Copy the postal code 59718 exactly: it is what routes the letter to Hauts-de-France, France.
The letter is addressed “À qui de droit,” and its details block uses the labels Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

Before you cancel Boutique So, 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.
