SMTP API works by sending emails using an external SMTP server. Here’s a simplified process:
1. Integration: First, you need to integrate the SMTP API with your application or email marketing platform. 2. Authentication: You’ll authenticate using your API key or SMTP credentials. 3. Compose: Create the email content, including subject line, body, attachments, and recipient addresses. 4. Send: The email is sent through the SMTP server, which handles the delivery. 5. Tracking: The server provides feedback on delivery status, open rates, and other analytics.
