E-mail notification for expiring date for each post

Hello! I’m planning to publish posts which has different authors and I would like to notify authors of each post independently when a post expires via e-mail. Is it possible to realize such option? And I also want to have these notifications send first within month till expiration date, then within 7 days till expiration date and within 1 day till expiration date and when the post changes status in the day of expired date also sen notification that the post date expired. And I want to change the text of these notification. I see you don’t have such options yet. So I’m new user and would like to purchase license for you plugin but due to lack of listed above options I can’t start using it. Please, give a feedback if you are going to realize these options in near future so I could get back and start using this plugin)
