Why do email signing certificates expire?

Security. Pure and simple. If email signing certificates never expired, they would outlive the individuals they’re authenticating and open up the potential for all kinds of impersonation and malfeasance. Not good. So instead Comodo requires you to undergo validation again every year or so, just to be sure that you’re still who you say you are. After all, there’s a lot of stock put into the digital signature provided by your email signing certificate.

That signature is the difference between the inbox and the spam folder in most cases. It can be business critical. It can also endanger the recipients of your email if it’s ever compromised. That’s why Comodo takes these certificates so seriously.
