It's appropriate when you need absolute mastery or are building with a very limited setup . However, EmailKit and similar libraries provide a abstracted abstraction , managing many frequent tasks like verification, issue resolution, and message building. This can result to more rapid construction and better consistency, but might create a slight speed penalty and an extra package. Consider your priorities carefully.

• Strength of Native SMTP: Direct Control
• Drawback of Native SMTP: Substantial Custom Coding
• Benefit of SMTPKit : Faster Development
• Drawback of MailKit: Potential Performance Penalty
