## Description

### Lightweight SMTP Plugin for WordPress with Email Logs

[**Authority Mailer SMTP**](https://www.authorityplugins.com/products/authority-mailer-smtp)
is a **WordPress SMTP plugin** designed to fix **WordPress emails not sending**,
improve email deliverability and spam issues.

By default, WordPress sends emails using PHP mail, which often fails or sends emails
to spam.

Authority Mailer SMTP replaces PHP mail with secure SMTP or API-based delivery, 
ensuring emails from WordPress, WooCommerce, contact forms, and membership plugins
reach inboxes reliably by hooking into wp_mail().

❌ **Missing WooCommerce orders?**
 ❌ **Contact form emails not reaching your inbox?**
❌ **Password reset emails not arriving?** ❌ **Clients saying “we never got the
email”?**

Authority Mailer SMTP fixes WordPress email delivery by replacing unreliable PHP
mail with secure SMTP or API-based sending.

providers.

### SMTP Configuration Guide

SMTP (Simple Mail Transfer Protocol) is the standard for sending emails. Here’s 
what you need to know:

**SMTP vs API Methods:**
 – **SMTP:** Traditional protocol, works everywhere, slightly
slower – **API:** Faster, more reliable, provider-specific – Most providers support
both; Authority Mailer uses the faster API when available

**Essential SMTP Settings:**
 – **Host:** Server address (e.g., smtp.sendgrid.net)–**
Port:** Usually 587 (TLS) or 465 (SSL) – **Username:** Usually email or account 
ID – **Password:** API key or account password – **Encryption:** TLS (port 587) 
preferred over SSL

**Troubleshooting Connection Issues:**
 1. Verify credentials are correct 2. Check
firewall allows outbound SMTP traffic 3. Ensure port 587 or 465 is not blocked 4.
Test with Authority Mailer’s test email feature 5. Check email logs for specific
error messages

### Email Delivery Best Practices

**Sender Reputation**
 – Send only to opted-in recipients – Honor unsubscribe requests
promptly – Monitor bounce and complaint rates – Use consistent “From” address

**Authentication Protocols**
 – Enable DKIM signing (provider-managed) – Configure
SPF records in DNS – Implement DMARC policy – Use domain alignment for authentication

**Email Content**
 – Avoid spam trigger words – Balance text and images – Include
physical address (CAN-SPAM compliance) – Provide clear unsubscribe link

**List Management**
 – Remove hard bounces immediately – Suppress repeat complainers–
Segment by engagement level – Clean lists before migrations
