The signature represents more than just an “email signature”. It is really important because it provides contact information, our name and profession. We can add certain very positive data about us, the product or service we offer, etc.

  • Name.
  • Job title.
  • Contact methods: social media, phone number, email, etc.
  • Links for a call to action.
  • A small image or logo of the company.

Additionally, we do not recommend using colors of any kind, unless they are flashy like bright neon. The idea is to use black, italic or bold colors to highlight some interesting data. The idea is to make it as professional and simple as possible.
