How WordPress Sends Emails (The Real Problem)
By default, WordPress uses the PHP mail() function to send emails.
Sounds simple — but here’s the problem:
Most hosting servers do not trust PHP mail
Emails are often blocked, delayed, or marked as spam
Modern email providers (Gmail, Outlook, Yahoo) reject unauthenticated emails
So even if WordPress thinks it sent the email, the recipient never gets it.
That’s why:
-
No errors appear
-
Forms submit successfully
-
Orders complete
-
But emails never arrive
Common Symptoms of WordPress Email Issues
If you’re experiencing any of the following, this guide is for you:
-
WordPress password reset email not sending
-
WooCommerce order emails not received
-
Contact Form 7 not sending emails
-
Elementor form emails missing
-
WP admin email change confirmation not received
-
User registration emails not arriving
-
Emails going to spam instead of inbox
Top Reasons Why WordPress Emails Are Not Sending
Let’s break this down properly. If your WordPress emails are not sending and you don’t want to waste hours debugging SMTP, DNS, or hosting issues, you can get emergency WordPress support from WPThrill and have the problem fixed today.
Get Emergency WordPress Support
No SMTP Configuration (Most Common Cause)
WordPress does not include SMTP by default.
Without SMTP:
-
Emails lack authentication
-
Servers flag them as suspicious
-
ISPs block or silently drop them
This alone causes 80%+ email issues in WordPress
Hosting Provider Blocking PHP Mail
Many hosts:
-
Disable PHP mail entirely
-
Rate-limit outgoing emails
-
Block emails without SPF/DKIM
Especially common with:
-
Shared hosting
-
Cheap hosting plans
-
Security-hardened servers
Missing or Incorrect SPF, DKIM, DMARC
These are email authentication records.
Without them:
-
Gmail rejects your emails
-
Outlook marks them as spam
-
Yahoo silently drops them
Most site owners never configure these — but email providers expect them.
Wrong “From” Email Address
Using:
on your domain:
This is a guaranteed failure.
Your “From Email” must match your domain.
Plugin Conflicts
Some plugins:
-
Override wp_mail()
-
Block outgoing emails
-
Break form submissions
Common offenders:
-
Caching plugins
-
Security plugins
-
Email logging plugins
-
Misconfigured SMTP plugins
WooCommerce Email Settings Misconfigured
WooCommerce has its own email system. If you are specifically facing issues with WooCommerce order, invoice, or customer emails, follow our step-by-step guide to fix WooCommerce not sending emails.
If:
-
Emails are disabled
-
Templates are broken
-
SMTP isn’t connected
You’ll miss:
-
New order emails
-
Customer invoices
-
Password reset emails
Step-by-Step: How to Fix WordPress Emails Not Sending
Now let’s fix this properly.
Step 1: Install an SMTP Plugin (Mandatory)
You must use SMTP.
Recommended plugins:
-
WP Mail SMTP
-
FluentSMTP
-
Post SMTP Mailer
-
WP SMTP
For beginners, WP Mail SMTP is the easiest.
Configure SMTP (Gmail Example)
-
Install WP Mail SMTP
-
Choose SMTP or Gmail
-
Set:
-
From Email:
no-reply@yourdomain.com -
From Name: Your Site Name
-
-
Enable authentication
-
Enter SMTP credentials
-
Save settings
-
Send test email
If test email works — WordPress emails are fixed.
Step 2: Use a Reliable SMTP Provider
Avoid using:
-
PHP mail
-
Shared hosting SMTP
Use one of these instead:
-
Google Workspace
-
Outlook SMTP
-
Zoho Mail
-
Amazon SES
-
SendGrid
-
Mailgun
These providers guarantee deliverability.
Step 3: Fix SPF, DKIM, and DMARC
Add these DNS records in your domain:
-
SPF – authorizes sending servers
-
DKIM – signs emails cryptographically
-
DMARC – enforces email policy
Most SMTP providers give copy-paste DNS values.
Without this, emails may still land in spam.
Fix WooCommerce Emails Not Sending
If WooCommerce emails are failing:
Checklist:
-
SMTP plugin active
-
Test email successful
-
WooCommerce → Settings → Emails
-
Ensure emails are enabled
-
Check recipient email addresses
-
Regenerate email templates if overridden
WooCommerce emails depend entirely on WordPress email system.
Fix SMTP = fix WooCommerce emails.
Fix Contact Form Emails (CF7, Elementor, WPForms)
Forms often fail because:
-
“To” email is Gmail/Yahoo
-
“From” email doesn’t match domain
Best Practice:
-
From Email:
forms@yourdomain.com -
To Email: your inbox
-
Enable SMTP
-
Use Reply-To instead of From
Step 4: Test Emails Properly
Use:
-
WP Mail SMTP → Email Test
-
Email Log plugin
-
Temporary inbox (Mailtrap)
If emails:
-
Send but don’t arrive → DNS issue
-
Don’t send at all → SMTP config issue
Step 5: Check Hosting Restrictions
Contact your host and ask:
-
Is PHP mail enabled?
-
Is outbound SMTP blocked?
-
Any email rate limits?
-
Is port 587 open?
Some hosts block SMTP by default.
Advanced Fixes (For Persistent Issues)
-
Disable all plugins temporarily. In many cases, WordPress email issues are caused by plugin conflicts. If you cannot access the admin dashboard, follow this guide to disable WordPress plugins without admin access and identify the issue safely.
-
Switch to default theme
-
Enable WP_DEBUG. f WordPress emails are still not sending and no error is visible, enabling debug mode can reveal hidden PHP or plugin-related issues. Follow this guide to enable WordPress debug mode to find errors safely.
-
Check server error logs
-
Reset wp_mail hooks
-
Clear object cache
-
Disable Cloudflare email obfuscation
Prevent WordPress Email Issues Forever

Avoid PHP mail
Log all emails
