# SMTP Configuration

### **SMTP (Simple Mail Transfer Protocol):**

* SMTP is used for sending transactional emails such as preorder confirmations, payment instructions, shipping updates, and status notifications. By configuring a custom SMTP server, businesses can manage email deliverability, branding (e.g., custom sender domain), and compliance more effectively.

### **Email API Integration:**

* In addition to SMTP, the application supports integration with popular email service providers (ESPs) via their APIs (e.g., SendGrid, Mailgun, or Amazon SES). This approach allows faster delivery, better tracking (open/click rates), and more advanced features like templating, batch sending, and analytics.
* Together, SMTP and API options give businesses the flexibility to choose the best method for their needs, whether prioritizing simplicity, control, or scalability.
