When mixing AND and OR in an ON clause or a WHERE clause you need to include brackets e.g.

SQL

LEFT JOIN Contact c ON b.id = c.broadcast_Id 
                      and c.Created_by = 1 
                      and c.isdeleted = 0
                      and 
                      (
                          c.sms_sub = 'subscribe'
                          or c.eml_sub = 'subscribe'
                          or c.whtsap_sub = 'subscribe'
                      )

Hopefully this article will explain why this is necessarySQL: Using Parentheses with And / OR condition is necessary with where clause to gives expected result - Codepedia[^]
