Sometimes I have worries regarding which salutation I should use on email correspondence. My concern really is in regards to those I correspond with repetitively.
My job is somewhat “customer-service” oriented; therefore I want to attempt to provide some thoughtfulness and respect. I continuously change my salutation from my 1st time correspondence (Kind regards) to my 2nd thru 300th correspondence salutation (Regards).

Today, however, I implement my new ALL correspondence salutation:

Peace,
