Email hello@gymdaypasses.com. It is read by the person who builds the site, and every message gets to a human.
These are the messages we most want. A wrong figure here sends somebody to a front desk expecting the wrong bill, so corrections go to the top of the pile.
To let us act quickly, please include:
Tell us which gym is missing and we will look for a readable official source. Some chains publish no day-pass figure anywhere; those get a policy-only page rather than an invented price, and some are absent because we could not verify anything worth publishing. If you know where a chain publishes its rates, that is genuinely useful.
Same address. We are not affiliated with any gym chain, and we do not accept payment to change a result or to feature a gym — that is not a policy we bend.
