I went to Bali and Hawaii and recorded every message I sent and received when setting my shoots there so you can follow along line by line to see what works.
I've messaged hundreds of potenial models and found what gives the highest chance of someone getting back to you. I've done this with my @sasserstillsboudoir instagram account that has over 50,000 followers, and I've done this with my old account that has 5 boudoir pictures and under 3,000 followers. It works for both.
