signatures

Adding a signature to an email looks professional. People know how to reach you outside the internet. They know your name and where you live, what can also be problematic, in case that the email is read by people you don’t want to know such personal things. Your email can be abused for spamming, your postal address tells a lot about you. But sometimes, a signature is necessary. You have to evaluate for every email if you add a signature, but the danger of spam mails is always there.
