What’s the best way to thank someone for referring me to a job? We’ve actually never met personally but I was referred to her via email from a friend of a friend. Anyway, I got the job and I want to thank her for the referral in a courteous and professional manner. I think she’s also married so I don’t want to send the wrong signal or create any household problems for her. Should I mail her a gift, a card, or maybe something else? Any ideas?
