Want to be remembered by the potential client with whom you’ve just had an unsuccessful negotiation? Take the time to send a “Thank You” card. That’s right, a snail-mail Thank You card. Create a one off, nice looking card on your color printer on nice paper, and hand write a note, something like, “Thank you for the opportunity to provide an estimate for your upcoming project. Although we couldn’t work together this time, please keep me in mind for future projects. I am confident that together we would create compelling photographs that show off the best that [insert company name here] has to offer.”
These days, very few photographers take the time to use the US Postal System, instead opting for the more impersonal, faster-to-send, email message. This sort of tasteful, snail-mail contact after a failed negotiation will differentiate you from your competitors and provide another opportunity to show your work to the client. I’ve done this for years and it works; I’ve been contacted for subsequent job estimates and was awarded the work. Good luck!
