Subscription-Trademark-License and Kickstarter

Hello everyone.
I want to run a fundraising campaign on Kickstarter.
And I am interested in the procedure of approval of promotional materials.
The license has a point:

I need to make a promotional video for at least 30 days earlier than the start of the campaign?
And send it for approval to Epic?

Many people have already seen this, could you explain to me the procedure?

It means, to use the UE4 logo on your promotional materials, you have to submit everything that you want to use it for to Epic. If they don’t respond within 30 days then it’s automatically approved.

Where can I find contact email ?
