How to cancel Regime Dukan by mail
Find your account details
Check the account email, the plan name and any pending order or prescription reference before anything else. A request that does not match the account on file at Regime Dukan is the easiest one to set aside.
Prepare the letter
Postbye writes the letter in French from our French template, because Regime Dukan's address is in France. It opens with the subject line “Objet : Demande d'annulation – [your name]” and asks Regime Dukan to end the subscription, stop all further charges and confirm in writing.
Mail it with tracking
Send it certified to Paris, 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 Regime Dukan received your letter. Check your next statement: no Regime Dukan charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Cancelling a health or wellness subscription
Health and wellness plans combine a monthly fee with supplies or consultations, so the request should say what to stop: the plan, pending shipments or both.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
