Where to send your Flex cancellation letter
Read the addresses on this page next to the full guide to cancelling Flex.
The addresses we hold
One place for Flex's mailing addresses: the Miami delivery point for a cancellation letter first, then the rest of what the database holds, with envelope wording that matches.
Where the letter goesMailing address
FlexNortheast 191st Street 3908019Miami 33179Flex takes its post at this Miami address (ZIP 33179).
How to address the envelope
Use the address letter for letter
One address block, copied whole: Northeast 191st Street 390, 8019, Miami 33179. If any line differs from the card above, start the envelope again.
Add the return address
Print your return address in the top-left corner. Without it, an undeliverable letter is simply lost instead of returned to you.
Send it certified
At the counter, certified mail costs a fee on top of the postage and comes with a mailing receipt and a delivery record. The tracking number on the green label is what you follow.
Keep the proof together
Hold on to the letter copy, the receipt and the tracking page.
The letter to send
What the letter to Flex says: one clear cancellation request, no reasons given, the account email, the last four digits of the linked bank account or card and the membership tier quoted, and a request for written confirmation.
