I just had some correspondence with a fellow whose email signature was a poorly formatted mess. Fixing it would improve both his personal and his corporate branding.
Give some thought to the information you include in your email signature, and how it's laid out.
You don't want it to run too long, but include basic contact info, maybe a tag line about your company, and your website or (maybe) social media URLs. Include the https:// bit so they'll be clickable for every recipient.
Make sure your sig is consistent across all devices that you might be emailing from.
While you're at it, check your name that will show in the recipient's inbox. Does it make clear who you are so you'll show up well in a crowded inbox? Edit if needed, and again, be consistent across your devices.
Recommend these steps to your employees, too. It might be useful to provide a pre-written blurb for them to use as their email sig so that emails from across your company create a consistent impression.
Polishing your email sig is a once-and-done task that's a small but positive support for your branding, both personal and corporate.
