How to cancel Gainful by mail
Collect the details you need
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Gainful can only act on a request it can match to an account.
Prepare the letter
Your Postbye letter to Gainful asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Subscription termination – Gainful”. It comes from our English template.
Send the letter by certified mail
Use certified mail for the 10011 New York address in the next section, so the post office records the delivery. Write down the tracking number.
Save the tracking record
File the receipt with the letter. A Gainful charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Gainful cancellation letter goes
Gainful takes its post at 6 West 18th St, Suite 10F, New York, NY 10011, which is where a cancellation letter belongs.
Put ZIP 10011 on the envelope: New York is in New York, and a domestic certified letter is all it takes.
The database also lists West 25th Street 137, 6th floor, New York 10001 for Gainful. Use the first address above unless your agreement names this one.
Inside, the salutation reads “To Whom It May Concern,”, followed by your details under Name, Address and E-mail.

Before you cancel Gainful, check these
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- 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.
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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
