With a custom HTML email signature, you are mainly handing out a business card with every email you send. It’s great for reminding people who you are and what your business is. But, of course, to make a good impression, you’d want a good card.
Great stock (couché, vergê, supreme), a right font, and an attractive design will give someone a much better impression than a page torn off a notebook with your name, email, and phone number. In the same way, you should be conscious about your email signature because it may make more of a difference than you think.
