Your Mama gave you lots to work with, so use it! Hopefully by now “please” and “thank you” are regular participants in your vocabulary. If not, start practicing ASAP!
How can you make your please or thank you stand out? There are some obvious ways, like simply using your lips to form the words, which are helpful. If you have that part down, though, try moving on to something more evolved to show appreciation. Another easy answer is a “thank you” card.
Talent can use postcards to send a gentle reminder and thank you to casting directors, producers, and directors, after being seen or having worked with them on set. A simple post card with your branded image works well to boost your likeness in their mind. Notes on these postcards or thank you cards should not be lengthy, but must be specific and unique! A simple “thank you for your time” would be better than a novel three page letter about your favorite moments or over-complimentary view of their work. My recommendation would be two or three sentences to show appreciation, recognition, and individuality – short and sweet.
A secondary follow up after the dust has settled is a positive reinforcement they will emotionally connect with your face. Those warm fuzzies will turn into an added advantage on their next casting or project!
