How to cancel Peptiva by mail
Gather 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 Peptiva holds, so the request can be matched to your account.
Write your request
Your Postbye letter to Peptiva asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Subscription termination – Peptiva”. It comes from our English template.
Post it with proof of delivery
Use certified mail for the 84119-1137 Salt Lake City address in the next section, so the post office records the delivery. Write down the tracking number.
Hold on to the receipt
It shows the date Peptiva received your letter. Check your next statement: no Peptiva charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Peptiva, check these
- Use the same name and email as on the account. A mismatch can delay the request.

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 letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
