A quick clarification about your email signatures. When you send an email to anyone without @nanjing-school.com on the end of their address, there is automatically attached to it a digital business card signature. It looks like this:
It allows our emails to be whitelisted by those who receive them more frequently than going into the receiver’s Spam box, not to mention gives our emails a more professional veneer. We recommend that whatever signature you choose to put in your emails at least indicate your full name and role at the school, but of course we do leave it up to you. This is something good to keep in mind in discussions with students about their own email etiquette when using the school email. Happy Emailing!
