How to cancel Lunion 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 Lunion holds, so the request can be matched to your account.
Put the request in writing
Because Lunion 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 the letter
Send it certified to Lille, France, copying the address from the next section letter for letter, and keep the receipt slip.
Keep the proof of delivery
The receipt dates your request. Look at your next statement for any Lunion charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.

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