How to cancel Flaviar by mail
Get your account details together
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Flaviar can only act on a request it can match to an account.
Prepare the letter
Your Postbye letter to Flaviar asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Subscription termination – Flaviar”. It comes from our English template.
Post it with proof of delivery
Use certified mail for the 10001 New York address in the next section, so the post office records the delivery. Write down the tracking number.
Keep the proof of delivery
File the receipt with the letter. A Flaviar 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 Flaviar cancellation letter goes
For a letter to Flaviar, use 244 5th Ave, Suite F247, New York, NY 10001.
Put ZIP 10001 on the envelope: New York is in New York, and a domestic certified letter is all it takes.
The database also lists William Street 123, Floor 21, New York 10038 for Flaviar. Use the first address above unless your agreement names this one.
The letter is addressed “To Whom It May Concern,” and its details block uses the labels Name, Address and E-mail.

Before you cancel Flaviar, check these
- Use the same name and email as on the account. A mismatch can delay the request.
- Check your next statement: no charge should appear after the cancellation date.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.

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.
