An Email Subject Line Rabbit Hole

I received an email recently with the subject line: “A WING AND A PRAYER.”

My GenX pop-culture brain immediately referenced “The Greatest American Hero” theme song. If you don’t know it, “The Greatest American Hero” was a show about a guy who receives a superhero suit from aliens, but does not know how to use it because he lost the instruction manual. Ah, TV in the early '80s!

It could very well be that this was not the intent of the subject line. “A wing and a prayer,” is a pretty common phrase meaning hope with very little chance of success.

I have some questions about the email:

Would the subject line inspire you to open it?
Does it pique your curiosity?
Is it too clever?
What benefit is there to opening it?
How well did this email perform for the sender?
