    Email signatures are an important way of showcasing your brand and marketing your business. Most people send and receive dozens of emails a day.

    Branded emails give your customers — and maybe more importantly, your leads — a simple way to see how to contact you and learn more about your brand.

    For example, most email signatures will have social media links. If you send an email to a lead, even if they don’t respond to you, they might use those links to check you out on social media or take a look at your website.

    And for current clients, a slick email signature makes you look more professional. It makes them feel like they’re working with a high-quality brand. It’s pretty much expected in the business world.

    Unfortunately, many email programs (like Gmail, Outlook, and Apple Mail) don’t exactly have great email signature options.

    Sure, you can design your own in HTML, but for most business professionals, HTML just isn’t a tool in their toolkit.

    There are some basic options in Gmail, Outlook, and Apple Mail, but nothing like the high-quality signatures that many email signature generators today can create.

    Using an email signature generator is really the only way to create a branded signature that looks great, gives clients and leads the information they need, and boosts the visibility and professionalism of you and your brand.

    Some email signature generators (like Mailbutler's) even allow you to create marketing messages or banners so that you can include links to coupons, downloadables, videos, or anything else a potential customer might find useful.

    Even if they don’t respond to your email, this secondary CTA can move them to action, giving you a second chance of connecting with them (or even making a sale).

    Here are some of the best email signature generators on the market today.
