How to cancel So Lonely by mail
Gather your account details
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at So Lonely is the easiest one to set aside.
Draft the request
Postbye drafts the request in French, the language of France, with “Objet : Demande d'annulation – [your name]” as the subject line. It asks So Lonely to close the subscription, stop billing and confirm in writing.
Send it by certified mail
Mail the letter by certified mail to the Lille address in the next section, and keep the tracking number.
File the delivery record
Keep the tracking record with your copy of the letter. If So Lonely bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your So Lonely cancellation letter goes
So Lonely can be reached by post at CS 90006, 59718 Lille, France.
The postcode 59718 belongs to Hauts-de-France, France, so this is where the envelope is delivered.
Your details go in a block headed by Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré, and the opening line is “À qui de droit,”.

Before you cancel So Lonely, check these
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- 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.
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.
