It differs from Gmail Service by only sending emails, lacking access to Gmail accounts. The `MailApp` class facilitates this with methods like `sendEmail()` to dispatch messages, accepting variations in arguments for recipients, subject, body, and options. `getRemainingDailyQuota()` method returns the number of remaining recipients allowed for the day.
