Your time is valuable! Mine is as well!

Cold-writing potential candidates can be very time-consuming.
Even when using very personalized messages you can't be sure about getting an answer let alone the person might be interested.
I used to answer all requests until recently. It just consumed too much of my time even when using templates.
So I thought having some information in advance might make it easier for both sides.
You can see if there's at least a chance getting to me. And I don't have to answer so many requests anymore.
To save us some time you could start answering a few questions which translate to my current preferences.
If I might be interested or not you'll know after answering all the questions.
