The short answer
A FASTMAIL* PTY charge is an ad-free email hosting, custom domain email, and calendar subscription from Fastmail Pty Ltd.
Why it shows up like this
A billing entry marked FASTMAIL* PTY indicates a software subscription charge from Fastmail Pty Ltd, an independent, privacy-first communications company based in Melbourne, Australia, with extensive operations across the United States. Fastmail Private Email Hosting provides ad-free personal and business mailboxes, synchronized calendars, and contact management. Users seeking privacy often choose Fastmail as an alternative to big-tech platforms like Google Workspace or Microsoft 365 to handle personal mail or custom domain routing.
This charge appears because an account reached its monthly or annual renewal date, or because a thirty-day trial converted to a paid billing plan. Fastmail offers several tiers, including a Basic plan billed at $36 annually, a Standard plan for custom domain users billed at $5 monthly or $60 yearly, and a Professional tier. Because many subscribers select annual billing to lock in lower rates, the yearly renewal often catches account owners by surprise twelve months after their original purchase.
If you do not recognize this charge, check whether an authorized family member or business partner uses Fastmail to manage personal email accounts. You can verify active subscriptions by signing into app.fastmail.com and navigating to Settings under Billing and Plan. Fastmail allows cardholders to export email archives and cancel auto-renewals at any time, and their customer support team offers a thirty-day refund window on unintended annual renewals. For completely unauthorized charges, notify your credit card company right away to initiate a dispute.
