Signguin

Signguin is a free email signature generator for small businesses. Type your work email and Signguin finds your company's logo and brand colors on your website, fills in your name and contact details, and builds a signature you can add to Gmail, Outlook or Apple Mail in about two minutes. No sign-up is needed to create one.

Pick from designs made for different kinds of business, from florists and trades to law firms, real estate and software teams. Every design takes on your logo and colors. The HTML is tested to display correctly in Outlook, which is where hand-made signatures usually break.

The free plan includes 3 designs. Premium is a one-time payment, not a subscription: it adds your photo, all designs, action buttons, banners, a Save contact link, and removes the small "Made with Signguin" link. Available in 20+ languages.
