SMTP Configuration

The preorder application integrates both SMTP and API-based email delivery systems to ensure reliable and flexible communication with users.

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.
