The verb “é” is unnecessary; “isso mesmo” already functions as a complete affirmation.
Sim isso mesmo
Missing the comma makes the phrase sound rushed; the pause after “Sim” is natural in spoken Portuguese.

Cultural Tip
In Brazil the phrase is informal and often spoken with a slight upward intonation, signalling enthusiasm. It’s common in friendly chats, but you would avoid it in very formal settings (e.g., a business meeting) where a simple “Sim, está correto” would be more appropriate. Regional accents may slightly change the vowel quality of “mesmo,” but the meaning stays the same across the country.
