It has taken some time for me to get around to this email, as I meant to inform you that I started a new job at ———— last year in October. The job, salary etc. is great, and I owe it all to the excellent work you did on my CV and LinkedIn Profile.
I have spread the word. I would like to stay in touch with you. You are really good at what you do and am happy to work with you on an annual basis as to keep my CV and profile updated, if not more frequent than that.
Take care & warm regards
