How to cancel Instaflex by mail
Gather your account details
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to Instaflex is only as good as the details it quotes.
Set out the request
Your Postbye letter to Instaflex asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Subscription termination – Instaflex”. It comes from our English template.
Send it by certified mail
Address the envelope to Instaflex, West Valley City, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Send the email copy
Email Support@instaflex.com with the same request and keep the sent message. The email is fast; the letter is the dated proof.
Hold on to the receipt
The receipt dates your request. Look at your next statement for any Instaflex charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Instaflex, check these
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
With two routes open, use both: the email is fast and the letter is the dated paper proof.
