This is how a promo is supposed to work. You open one and you are intrigued by the image so you go visit the photographers website. You really like what you see, so you file the promo away or tack it to your board, but then you head off to a meeting or go home for the day and immediately forget about the photographer.
Then the promos keep coming in (every month or two or three) and each time you are reminded how much you liked their work and each time you are enjoying the new image and then you begin to look forward to seeing the next one and then you start recognizing the envelopes when they come in. Eventually, you will hire them. This is how it is supposed to work and that why Sarah Wilmer deserves a special mention for sending promos in 2015.
