Magento 2: Sending Emails Guide

Magento supports common transactional emails such as account confirmations, password resets, order updates, payments, invoices, and review requests through built-in templates that can be customized in the admin panel rather than by editing core files. When default triggers are insufficient, developers can create or modify templates, supply variables and sender details, preview rendered messages, and send emails programmatically using Magento and Zend Mail capabilities. Because Magento commonly relies on PHP’s mail() function by default, which can create deliverability and security issues, the text recommends configuring SMTP through third-party extensions and an SMTP provider, with optional delivery tracking and unsubscribe tools for marketing messages. It also emphasizes testing emails in a safe staging environment to validate content, rendering, spam risk, links, and SMTP details before customer delivery. Common troubleshooting measures include updating Magento, reviewing store email addresses and email communication settings, disabling asynchronous sending where appropriate, checking server logs and SMTP settings, clearing cache, and identifying potentially conflicting modules.
