If you've read our other articles, you know that we do not automatically post the Numbers for you. This is a manual process kicked off by you, whether you upload your own specific numbers or you rely on us to randomize them for you. Either way, you trigger that in real time.
When you post the Numbers, an email is sent out to each of your players simply informing them that the Numbers have been posted to your Contest.
The Numbers themselves are not in the email - only a link to the Contest encouraging them to come see for themselves.
It is a good practice to email your players before you post the Numbers, letting them know you are about to do it. Or at the very least, informing them that you've just done it - this way they are less suspicious that you were tinkering with the numbers yourself and hoping to get away with something nefarious.
It's also a good practice because our emails are automated, and some mail programs consider messages like ours to be SPAM, and will filter those out of your player inboxes. If you were to reach out to your contest email list directly, it would more likely ensure that everyone was aware.
