Here is a way to go:

  • Find what: ^(?:[^a-z@]*[a-z]){0,3}[^a-z@]*@.+(?:\R|$)
  • Replace with: EMPTY
  • Replace all


^           : begining of line
(?:         : start non capture group
  [^a-z@]*  : 0 or more non alphabetic or @
  [a-z]     : an alphabetic
){0,3}      : group exists from 0 up to 3 times
[^a-z@]*    : 0 or more non alphabetic or @
@           : literally @
.+          : 1 or more any character but newline
(?:\R|$)    : any kind of linebreak (\r, \n, \r\n) or end of line

DO NOT CHECK . matches newline
