Hey there,
Yes, I will becareful on this because I knew you have setup the autopost in your site.
By the way, I just created a test post, it will send to your custom email address and mine, can you see is it will receive multiple notification email for which new post is published?
Because I already disabled that `send email via page load` setting from your backend before I publish my test post, you can refer on my attached screenshot below.
keep us updated then result.
