Sometimes download emails go missing. Before you get in touch, here are a few steps you can try.
1: Check any alternative email addresses. If you use Paypal we'll automatically mail your Paypal address, which is not always the address you use day-to-day.
2: Check inside your spam folder. If the email is spammed, make sure to click "not spam" so future emails arrive safely.
If you still can't find the email, contact support!
