As of this time, limiting the email received from QuickBooks is unavailable. You'll continue to receive an email coming from QuickBooks as long as your customers will email you or if you have an active account.
However, this is affecting your experience, I'll personally pass along these requests to our product developers. So that they'll know the preferred settings you need. To stay updated on new features and options, I recommend visiting this link: https://www.firmofthefuture.com/product-industry-news/product-updates/.
