Im wondering if there is a button to get a notification to your email if your ''Plan to Watch'' Drama is Airing or starting to Air.

Just why not !?

Notifications when drama on PTW list starts airing its suggestion given not implemented yet , you can give vote and opinion here

Meanwhile, I combine MDL with SIMKL who even send you and email alert when your preferred shows are going to be trasmitted.
