Subject: Updated Rate Schedule — Effective [DATE]

Hi [Name],

I wanted to give you advance notice that my rate will be increasing from $[OLD_RATE] to $[NEW_RATE] per hour, effective [DATE].

I value our working relationship and appreciate your understanding. I'm confident the continued quality of work justifies this adjustment.

Please let me know if you have any questions.
