How to cancel Smgp by mail
Find your account details
Smgp will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Write the cancellation request
Smgp 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.
Send the letter by certified mail
Send it certified to Clichy, 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 Smgp received your letter. Check your next statement: no Smgp charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Smgp, 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.
