Here is an example of an email signature quote:
Vice President of Marketing, ABC Corporation
“Morality is the basis of things and truth is the substance of all morality.” – Mahatma Gandhi
Email signature quotes often include some type of idealistic or moralistic message. These messages will often receive a very warm reception when they are delivered by those who are globally held in high regard due to their lifetime contributions to society but when they are delivered by a person who does not meet this criteria the tone of the entire email changes.
Take John Doe for instance. If John is known for gossiping about others or berating employees who take a lunch break then quoting Gandhi in his email signature is probably going to unleash some serious mockery.
Proceed with caution.
