How would you market to Short Term Rentals?

My venture is: making 3D Floor Plans for Short-Term Rentals

How I got the idea: I noticed that when booking for vacation, the pictures often didn't portray the actual space of the rental, I could never quickly understand where is what/what is where, the layout of the property, etc.

I have started sending cold Emails to Rental management agencies, 25 emails so far and 0 responses, but I can't know if they even reached the decision-maker.
As for AirBnB hosts, I can't message them one by one since AirBnB doesn't allow the sharing of details like an Email address.

You can see some samples I made for free so far in my page here:visualizedliving.com

Also feel free to roast my idea, any feedback is welcome :)
