1. Introduction
Transactional emails are crucial for keeping customers informed about their interactions with your business. Whether it's a purchase confirmation, a shipping notification, or a password reset email, these messages ensure a smooth customer experience. To ensure these emails reach their intended recipients promptly and securely, it's essential to follow SMTP (Simple Mail Transfer Protocol) best practices.

Choosing a reputable SMTP provider is the first step towards ensuring email deliverability. Look for providers with a proven track record in email delivery and excellent customer support.
