All products are delivered by automatic systems. It can take a few minutes for payments to process and trigger the email, but it should be in your inbox within 20 minutes of purchasing.
However, some email providers mark incoming emails as spam. So look in your SPAM and PROMOTIONAL folders for the name of the product you purchased and/or for firstname.lastname@example.org email.
If you still don't see it, send me an email and I'll get the product to you.
