How to cancel Phosphore by mail
Note your account details
You will need the name and email on the account and, if you have one, an account or customer number. Use exactly the details Phosphore holds, so the request can be matched to your account.
Draft the request
Phosphore is based in France, so the letter goes out in French, built from our French template. Subject line: “Objet : Demande d'annulation – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Mail it with tracking
Send it certified to Aubervilliers, France, copying the address from the next section letter for letter, and keep the receipt slip.
Hold on to the receipt
It shows the date Phosphore received your letter. Check your next statement: no Phosphore charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Phosphore, 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.

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.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
