Easily confused with
でないと でないと attaches to a specific condition within or across clauses ('if it isn't ~, then …'); さもないと stands alone at the head of a new sentence, pointing back to the whole previous statement ('do that — otherwise …'). なければ なければ is a neutral negative conditional ('if not ~'); さもないと is a standalone warning connector that always implies a threatening consequence.
Notes
- さもなくば is a literary equivalent; all share the 'or else' warning function.
