Remember, email is inherently insecure. Never email sensitive information, such as passwords or personal information like credit card numbers, passport numbers, social security numbers, and birthdates. DO NOT open attachments or click links in emails unless you know the sender and are expecting it. If in doubt, contact the sender (not over email in case their account is compromised). Do not let staff use personal email for official campaign business (using personal accounts put both the staff member and the campaign at risk).
