One address, and I read it myself: your@email.com
Expect a reply within 1–2 working days. If you're writing about an order, include the address you bought with or the Gumroad order number — it saves a round trip.
Didn't get your download?
Check your spam folder first, and search for "Gumroad". If it isn't there, email me and I'll send the files manually. Don't buy it twice.
Want a refund?
Just say so — no reason needed, within seven days. See the refund policy.
Found a mistake in the book?
Tell me. Prices move, parts get discontinued, and I'd rather correct it in the next edition than leave it wrong. Corrections go out free to everyone who owns the manual.
