SMTP for Magento 2 — Reliable Email Relay with OAuth2 & Logging

If your order emails land in spam, you lose the sale's trust

Out of the box, Magento hands your email to PHP's mail() function — which has no authentication, no deliverability reputation, and no way to tell you when a message vanished. Order confirmations land in spam, password resets never arrive, and you only find out when a customer emails to ask where their receipt is. SMTP routes every message through a real mail provider with proper authentication, so your transactional email actually reaches the inbox — and logs every send so you can prove it did.

What you'll use it for

• Fix deliverability — move off mail() to an authenticated provider so order, invoice and reset emails reach the inbox.
• Connect Gmail or Microsoft 365 securely — use OAuth 2.0 instead of app passwords, which both providers are phasing out.
• Audit what was sent — open the email log to see, preview and resend any message a customer says they never received.
• Protect your staging site — switch on dev mode so a test environment never accidentally emails real customers.

How it works

Works with the provider you already use

Nineteen presets cover the major providers (including four Amazon SES regions). Select one and the host, port, security and authentication fields fill themselves — or enter your own server by hand. Whatever you choose, you can add a plain-text alternative part to improve spam scoring, set a global CC/BCC for archiving, and define a Return-Path for bounce tracking.

Secure by design
