How Magento Emails Work: A Practical Guide

In Magento, email sending is vital for keeping users informed about orders, account activities, and promotions. This guide covers how Magento handles email functionality, SMTP configuration, and troubleshooting to improve deliverability, reliability, and security.

Why Magento’s Default Email Sending Falls Short

Magento relies on the PHP mail() function by default, which often causes emails to land in spam folders or fail due to lack of encryption. Without additional configurations, Magento’s email process lacks the secure delivery often required by modern email providers. For more reliable email sending, using SMTP or extensions is recommended.

Steps to Configure SMTP for Magento

  • Choose an SMTP Extension: SMTP extensions, like Mageplaza’s SMTP or Mailtrap’s API, ensure emails reach customers securely. After choosing an SMTP provider:
  • Set SMTP Credentials: Enter the SMTP host, port, username, and password provided by your email service. Adjust these for Gmail, Yahoo, or custom SMTP services based on provider guidelines.
  • Test Email Setup: Use Magento’s test email feature or an email testing service to ensure your setup works. Testing verifies that transactional emails reach customers without issues.

Email Automation and Transactional Emails

Magento automates email tasks through cron jobs, such as order confirmations, shipping updates, and password resets. Verify these jobs in Stores > Configuration > Sales Email to confirm that email triggers, such as new orders or shipping notices, work as intended.

Setting Purpose
SMTP Host Defines server for outgoing emails
Port Commonly 465 (SSL) or 587 (TLS)
Authentication Type Plain, Login, or CRAM-MD5 based on provider
Secure Connection Select SSL/TLS for encryption

If you rely on Magento, email functionality is critical for sending order confirmations, invoices, and shipping updates to your customers. But most Magento users, especially non-technical ones, may not fully understand how these emails are sent. While understanding Magento’s email process might seem minor, it becomes essential when troubleshooting email issues.

Magento’s email system is built on the Zend Framework, specifically the Zend_Mail class, with the key class for handling email being Zend_Mail_Transport_Sendmail.php. This class uses PHP Mail, which relies on the server’s sendmail script to handle the actual email-sending. However, one drawback is that this setup doesn’t support custom SMTP settings, which limits flexibility for server-side email configuration.
