How to cancel Simple Supplements by mail
Start with your account details
Before writing, collect the account email, the plan name and any pending order or prescription reference. Simple Supplements can only act on a request it can match to an account.
Prepare the letter
The letter asks Simple Supplements to end the account, stop every future charge and confirm it in writing, under the subject line “Subject: Subscription termination – Simple Supplements”. Postbye fills it in from our English template.
Post it with proof of delivery
Take the letter to the post office and ask for certified delivery to 94541 Hayward. Keep the tracking number it gives you.
Keep proof the letter arrived
Once the letter is delivered, the date on the receipt is the date Simple Supplements was told. Compare it with your statements over the next billing cycle.
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 phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
