Spark & Apple Script

Hi together,

Any possibility to get a return from the Mail client Spark if there is a mail from one specific sender?

Context: I have a Touch Bar button with a shortcut to this forum (and some others by the way). I would activate the mail notifications for new comments etc, and transform the button I have in the Touch Bar into an Apple Script that checks for new mail from that special sender. If triggered, it should set all mails from that sender to read and open the url to the forum.

Would work for Facebook notifications too.
Any ideas?
