I wonder if we can move this to a strings.parse_domain and do subdomain checking? This might handle more of these types of domains more fully

  or any(regex.iextract(sender.display_name,
                        '\b((?:[a-zA-Z0-9][-a-zA-Z0-9]*\.)+[a-zA-Z]{2,})\b'
         ),
         any(.groups, strings.parse_domain(.).sld == "amazon")
  )

)
or strings.ilevenshtein(sender.display_name, 'amazon.com') <= 1
or strings.ilevenshtein(sender.display_name, 'amazon pay') <= 1
