How to cancel UMZU by mail
Find your account details
Start with the account email, the plan name and any pending order or prescription reference, so the request to UMZU names the right account the first time.
Set out the request
Postbye turns the request into a finished English letter headed “Subject: Subscription termination – UMZU”: close the UMZU account, stop every charge and reply in writing.
Mail it with tracking
Send it certified to Boulder, United States, copying the address from the next section letter for letter, and keep the receipt slip.
Keep the proof of delivery
Delivery confirmation is your evidence that UMZU was asked. Watch the next statement or two for any further UMZU charge.
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.
