WooCommerce Waitlist

Idea for this plugin; Currently when items get back on stock (10 pieces), everybody on the waitlist gets an email (20 emails). However; waitlist is bigger then product availablity.

Should be great when it will be only the first 10 that get an email and then automated every 1 day (set this setting via backend) send a email to the next (1/2/3 (set this amount in setting also via backend) on the list) untill product is sold out again.
