Review your email signature block
From the Office of Professional Communications:
Please create a useful and informative signature block to use for email that goes to everyone who is not a Close Personal Friend.
Include COMPLETE contact information (name, address, phone). Please do not include philosophical musings or clever sayings which might detract from your professional image.
Without a signature block, you are a ghost in the machine to an employer who may need to write a letter or to call you. Also, please use a professional e-mail address – squeakybird@gmail.com is not professional.
