How to create an HTML Apple Mail signature?​

Making a working HTML signature for your Mac Mail is not as simple as one may think.

Even if you have a good eye for design and good knowledge of code (which most of us don’t), you’ll still have to build HTML that’s responsive for all the different devices and screen sizes out there, to make sure your signature doesn’t break.

What does a professional Apple Mail include?

  • Our name and job title
  • Your business name and logo
  • A high-quality photo of you
  • Your brand colors
  • Social media icons
  • Some business offer with a call to action (button, banner, video, link)

What not to include in my Apple Mail signature?

When trying to create the perfect Mac signature there’s sometimes a tendency to go overboard with design and features. Try to resist this urge if you encounter and you’ll end up with a cleaner, better looking, more effective email signature.

Look out for these 3 common mistakes:

1) Don’t use too many colors

Adding color to your email signature is a great idea. But adding too many colors? That’s a bad idea. A signature in an email should reflect your logo’s colors. If you don’t have one, go with the rule of thumb – 2 colors maximum – one main, one secondary.

2) Don’t overload your signature with calls to action

It’s smart to add buttons like “Follow us on Facebook” that prompt your email recipients to take action. However, do not add more than 2  calls-to-action within your signature – it will overload and confuse your readers. 

When you want people to take action, less is more. You want to direct your email readers to the most valuable actions (you shouldn’t have more than 1 or 2 of those). So, decide whether it’s a link to “Join our newsletter,” “Follow us on Facebook,” or “Shop our sale”, to give just a few examples.

3) Don’t use illegible fonts or too many font types

Some fonts are hard to read, such as cursive or decorated fonts. Using these will make people not wish to read your signature text and could possibly irritate most who see it. Keep to using clear fonts a 10-year-old could easily understand.

Some fonts are not compatible with most browsers and email apps. Have you ever received an email with a bunch of strange characters in gibberish?

That’s likely because the sender of the email did not use a web-safe font. A web-safe font is one that will consistently work across all devices and platforms (Apple, PC, iOS, Droid, etc).

We recommend choosing one of the following web-safe fonts: 

  • Courier
  • Georgia
  • Verdana

Another issue is using too many fonts.  Don’t mix font types, even if each of them is web-safe. It’s distracting and looks less professional. 1 signature 1 font – that’s your motto.

Yes. Apple Mac Mail supports HTML signatures, created two ways:

  • Write your own responsive HTML code by hand.
  • Use an email signature generator like WiseStamp to build and install the code for you.

Hand-coding requires HTML that stays responsive across every device and screen size.

HTML signatures break when the code is not built to adapt. Common causes:

  • Code that is not responsive across devices and screen sizes.
  • Incompatibility with certain email clients or apps.
  • Non-web-safe fonts that render as gibberish characters on some platforms.

A professional Mac Mail signature includes:

  • Your name and job title
  • Your business name and logo
  • A high-quality photo of you
  • Your brand colors
  • Social media icons
  • A business offer with a call to action (button, banner, video, or link)

Web-safe fonts display consistently across all devices and platforms. Recommended options:

  • Courier
  • Georgia
  • Verdana

Use one font per signature and avoid cursive or decorative fonts, which are hard to read.

Use two colors maximum, one main and one secondary, matched to your logo’s colors. Too many colors make a signature look cluttered and less professional.

Limit a signature to two calls to action at most. More than two overloads and confuses readers. Direct people to your most valuable actions, such as “Join our newsletter”, “Follow us on Facebook”, or “Shop our sale”.

Yes. WiseStamp’s internal research shows a professional signature boosts email reply rates and engagement by more than 20%. With the average worker receiving over 120 emails per day, a signature is an underused marketing channel.

Connect your active social channels using icons, buttons, or simple links. Add clear calls to action like “Connect with me on LinkedIn” or “Follow me on Instagram”. Link only to accounts you actively engage on.

Yes. WiseStamp’s signature generator builds and installs a signature with no coding. Steps:

  1. Open WiseStamp’s email signature maker.
  2. Add your professional details.
  3. Choose a template, then add social icons and links.
  4. Refine the design and add extras like buttons or banners.
  5. Click “OK I’m done”.

A signature created in Mac Mail on your desktop does not automatically sync to iPhone or iPad. Apple’s Mail app on iOS requires setting up the signature separately on each device.
