How to cancel Formula-app.com by mail
Get your account details together
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Formula-app.com names the right account the first time.
Set out the request
State plainly that you want the Formula-app.com account cancelled, further charges stopped and a written confirmation sent to you. Postbye sets this out in a ready English template (“Subject: Subscription termination – Formula-app.com”).
Mail it with tracking
Use certified mail for the 19904 Dover address in the next section, so the post office records the delivery. Write down the tracking number.
Save the tracking record
Keep the tracking record with your copy of the letter. If Formula-app.com bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Formula-app.com cancellation letter goes
Formula-app.com takes its post at 1111B S Governors Ave, STE 21968, Dover, DE 19904, which is where a cancellation letter belongs.
Put ZIP 19904 on the envelope: Dover is in Delaware, and a domestic certified letter is all it takes.

Every address we hold for Formula-app.com, with the envelope wording
Before you cancel Formula-app.com, 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.
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.
