We do our best to ensure that your emails get delivered, however depending on your shopper's email settings, the emails may end up in spam. Here are a few steps you can take to help:
(1) Change your email text to be unique. We send thousands of emails a day, most of which are the "default" text we provide.
(2) In the order notification email from your cart, add a note saying something like "Your download email will come from email@example.com. Please add this to your address book / safe senders list to ensure it doesn't get flagged as spam."
These steps should help ensure maximum deliverability.
