I need to be able to reply to just 1 email that I irregularly receive within seconds of it arriving. I want my iPhone to start vibrating etc. when it arrives.
Email is from firstname.lastname@example.org (the meetup website). Problem is I only want to be notified when 1 of about 100 emails/month arrive.
That target email can only be identified based on a text string in its body content together with its email subject line. It's not (not able to be) coming from a special email address nor is it able to be set to go to a unique address for myself. (They use 1 email they send from and I am limited to 1 email address to use to receive all 100 emails.)
I use gmail and Apple Mail on the Mac and have an iPhone. But my Mac is not on all the time.
How do I get my iPhone to vibrate at me when this email arrives?
