You send thousands of emails a year; every one closes with your signature. It's the most-seen piece of branding you own. A good one answers three questions instantly - who are you, what do you do, how do I reach you - and then gets out of the way.
Optional but effective: a small square headshot or logo (roughly 200x200px, under 100KB). Faces build trust in a way logos don't - use one if you're the product.

Email clients are where design goes to be humbled. The rules:
This is fiddly to hand-write, which is why we built a free email signature generator - three layouts, photo, brand color, and one-click copy that pastes cleanly into Gmail and Outlook with formatting intact.
Set it once on every device - the phone is where inconsistent signatures go to hide.
A crisp signature signals a professional operation; the operation itself is clear proposals, professional invoices and on-time follow-ups. That's the machinery BillingOtter runs for you - and the free tools cover the rest.
