How to cancel Instantly by mail
Start with 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 Instantly holds, so the request can be matched to your account.
Set out the request
Your Postbye letter to Instantly asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Subscription termination – Instantly”. It comes from our English template.
Send the letter by certified mail
Send the letter to the Sheridan mailing address shown below by certified mail. Keep the tracking number safe.
Save the tracking record
Delivery confirmation is your evidence that Instantly was asked. Watch the next statement or two for any further Instantly charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

Every address we hold for Instantly, with the envelope wording
Before you cancel Instantly, 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
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
