About Substack
Substack is a digital publishing platform that allows writers, journalists, coaches, and other creators to run their own newsletters and blogs with both free and paid subscription options. A descriptor like “COACHCHADJOHN.SUBSTACK” indicates a specific Substack publication or newsletter run by a creator using the Substack platform, with Substack acting as the merchant of record for billing. Subscribers can access posts via email and the web, often including premium articles, community access, or other member-only perks.
This charge appears on your bank or card statement when you subscribe to, or renew a subscription for, a specific Substack publication such as “Coach Chad John” on Substack. You may see recurring monthly or annual amounts, and sometimes a trial that converts into a paid plan if not cancelled. If you signed up using Apple Pay, Google Pay, or a saved card, the description will usually still reference the creator’s Substack publication name along with “Substack.”
To verify the charge, log into your Substack account using the email address where you receive newsletters from this creator, then go to your account settings and “Manage Subscriptions” to see active paid subscriptions and billing history. If you have questions or need a refund, you can either reply directly to any email from that Substack newsletter (which goes to the creator) or use Substack’s help pages to contact support. For unexpected charges, first check for multiple email addresses you might have used, look for past signup or trial confirmations from Substack, and then request cancellation or a refund promptly if you did not intend to continue the subscription.
