The idea that email signatures are a great place to market all of your new services or events was born before the smartphone. These days, when people are checking their email on a device that fits in their pocket, long email signatures overstuffed with info take up too much screen real estate and waste time.
Keep your signature short and sweet, hyperlink where necessary, and avoid any special design formatting – most phones just convert that to normal text now anyway, ensuring the recipient won't see your original color or font style.
