with fantastic news like this! Your team has been diligent
and never gave up. Thank you for your support and for
finding us such a terrific candidate.”

“Just a personal note: I wanted to let you know that we just received an acceptance and our CMO is extremely pleased. Also, I  wanted to say that I very much respect the fact that you continued to work on the position without an additional fee  to find a great candidate for us. Being a fellow recruiter, I feel this reflects very well – not only on yourself but the profession as well. I honestly believe that the majority of our colleagues would not have followed through in such a professional way.  Congratulations!”
