This plugin is an amazing toll to manage listings...
But i have one suggestion. .
Imagine we have a user who publish 100 lintings (i have 2 on my site ) when the the expiration date is coming, the user will receive 100 emails with warning the listing is about to expire, and a few days later will receive more 100 talling about the expired listings...
The idea is send just 1 email with a warning message "you have expired lintings in our site", and then that email shoul contain a link to access to expiring listings in user dashboard...
With this we save allot of emails...
This is just an idea...
Best regards
