Given more and more people are abusing single use or first-order coupons by creating new email accounts, the “excluded emails” field is pretty much used on every coupon in many stores. It would be great to have one site-wide “Excluded Emails” list where admins can add email addresses that should not be able to use *any* coupon on the site because they’re emails belonging to already existing users who are trying to abuse the system.

Totally get the pain here – even if you configure exclusions per coupon, it becomes repetitive admin work and it’s easy to miss edge cases when people rotate throwaway emails.
A helpful operational backstop is to visually flag coupon-heavy or discount-heavy orders right in the orders list, so they’re automatically routed for a quick check before dispatch even if you still implement stricter coupon rules elsewhere. You can use a plain text rule in orderbadger to achieve that – something like “The customer received a discount of more than 20 percent on this order” (paste that into the rule editor). Even better, you can flag email addresses using a blacklist, something like “if customer email address contains ‘spammonkey’ or ‘conmerchant'” and any orders with a matching customer email will be visually flagged! (but obviously use the email address patterns that you’ve observed to be problematic!). In order badger you just have to type in as though you’re explaining the rule to a colleague and it’ll figure out what you mean..
