A few days ago, I emailed support@itch.io to request approval for an email I wanted to send to my Kickstarter project backers with links to their products, but I didn't receive a receipt email, as the support page indicated. I'm not sure if I should resend the email or wait a few more days.

Also, I'd like to know if I will need approval for each email I send to a group of people using the Kickstarter feature in the future.

Thanks in advance for your help.
