Email signatures are a great way of adding some advertising and branding. You should always use a nice email signature for external emails . Internally, you shouldn't use any or just use a short one (just your name or initials).

Full email signatures are great when they have:

  • A little branding and advertising (can be a tagline or company news), so people know instantly who it is from
  • Your phone number (in international format - it's important to add the country code so people from all around the world can easily add you to their contacts - as per Do you know the right format to show phone numbers?)
  • Your company website link (e.g.
  • Your work-related social media and blog link
  • Your position
  • Your location (city/country) where you are based

Mobile signature are not easily customized so they can be simpler.

PC Long Signature

Use the complete "long signature" when sending a new email or appointment to a client.

This is created in HTML and goes well on emails with Word used as the email editor. Include some product advertising, like what's new on your monthly newsletter. It should have the company colors.

However, you shouldn't use your long signature on every sent email. It's recommended to have a simpler version for internal emails and appointments:

PC Short Signature

Use a really short signature (your first name or initials) or no signature at all in internal emails as people already know who you are.

Note #1: You can see Ulysses using this rule in practice, along with other best practices, on this short demonstration video.
