How to cancel 50 Power by mail
Get your account details together
Start with the name and email on the account and, if you have one, an account or customer number, so the request to 50 Power names the right account the first time.
Draft the request
Because 50 Power is dealt with in French, the letter is written in French (template fr). Subject: “Objet : Demande d'annulation – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Post it with proof of delivery
Send the letter to the Paris mailing address shown below by certified mail. Keep the tracking number safe.
Keep proof the letter arrived
Keep the tracking record with your copy of the letter. If 50 Power 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.

Before you cancel 50 Power, check these
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- 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.
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.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
