HTML Pro: How to prevent automatic links

Email clients automatically add links to certain keywords. This can happen to the following kinds of text:

  • URLs (,
  • email addresses (
  • phone numbers 
  • mailing addresses
  • dates
  • flight numbers

The problem is that if we don’t plan for them, these links will come up with their default styles (usually blue and underlined) — and this can create undesirable branding effects. 

Here are two possible ways to avoid automatic links:

  1. Use a zero-width non-joiner character. A zero-width non-joiner is an invisible character represented by the entity ‌ (or ͏) in the HTML source in the middle of text where a link might be added:
