How to cancel Solucia by mail
Gather 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 Solucia holds, so the request can be matched to your account.
Set out 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 Solucia to close the subscription, stop billing and confirm in writing.
Mail it with tracking
Take the letter to the post office and ask for certified delivery to 75013 Paris. Keep the tracking number it gives you.
Keep the proof of delivery
The receipt dates your request. Look at your next statement for any Solucia charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Solucia, 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.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
