How to cancel Hydrow by mail
Find your account details
Before writing, collect your membership number, the home club you joined at and the name on the membership agreement. Hydrow can only act on a request it can match to an account.
Set out the request
State plainly that you want the Hydrow account cancelled, further charges stopped and a written confirmation sent to you. Postbye sets this out in a ready English template (“Subject: Subscription termination – Hydrow”).
Mail it with tracking
Post it by certified mail to Hydrow in Boston, United States, using the exact address below, and note the tracking number.
Keep proof the letter arrived
Once the letter is delivered, the date on the receipt is the date Hydrow was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Hydrow, check these
- Annual fees and monthly dues are sometimes billed separately. Ask for both to be ended.
- A home club can have its own rules. Name the club in the letter so the request is not bounced between locations.
- Freezing or pausing a membership is not cancelling it. Say clearly that you want the membership ended.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a gym or fitness membership
Gyms often require written notice, set a notice window before the next billing date and can tie the cancellation to the home club, so a dated letter is the record that counts.
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.
