We’ve got the same problem!
It doesn’t have to be a free plugin, but it does have to be a reliable one that auto-generates and emails a single-use coupon code to a customer at the email address they enter (no purchase necessary). PDF coupons are resource-heavy overkill when all we need is a code, so those plugins aren’t much help.
So far we haven’t found any coupon plugins, opt-in plugins or Woocommerce plugins that do that but we’re new to this. Did you find anything?
