By default, WordPress sends all system-generated emails (like password resets, comment notifications, and admin alerts) using a generic sender name like “WordPress” and an email address like wordpress@yoursite.com. This not only looks unprofessional but can also hurt your email deliverability, as many spam filters automatically flag emails from unrecognized senders.
In this comprehensive 2025 guide, you’ll learn multiple proven methods to customize your WordPress email sender information, ensuring your emails:
âś…Â Look professional (with your brand name instead of “WordPress”)
✅ Avoid spam folders (improving deliverability)
✅ Increase open rates (by using a trusted sender identity)
We’ll cover:
- The easiest plugin method (using our recommended Email Sender Control plugin)
- Manual code solutions (for developers who prefer editing functions.php)
- SMTP configuration (for maximum email deliverability)
- Best practices to ensure your emails always reach the inbox

Why Change the Default WordPress Email Sender?
When you first install WordPress, all outgoing emails are sent with:
- Sender Name:Â “WordPress”
- Email Address:Â
wordpress@yoursite.com
This creates several problems:
Professionalism & Branding Issues
Imagine receiving these two emails:
| Default WordPress Email | Custom Branded Email |
|---|---|
| From: WordPress wordpress@yoursite.com | From: Md Asik Resources Support support@mdasik.com |
| Subject: Your password reset request | Subject: Your Md Asik Resources account password reset |
Which one would you trust more? Which one better represents your brand?
Email Deliverability Problems
Major email providers (Gmail, Outlook, Yahoo) use sophisticated spam filters that check:
🔹 Sender reputation (unknown senders get penalized)
🔹 Email authentication (SPF/DKIM/DMARC records)
🔹 Content consistency (generic senders raise red flags)
Using “WordPress” as your sender name lowers your email credibility, increasing the chance your important notifications:
❌ Get marked as spam
❌ Get automatically deleted
❌ Never reach your users
User Trust & Engagement
Studies show that emails with:
- A recognizable sender name have higher open rates
- A branded domain email (e.g., @yourdomain.com) appear more trustworthy
For example:
“Password reset emails from ‘WordPress’ get 27% lower open rates than those sent from a branded name like ‘YourSite Support'” – Email Deliverability Report 2024
Compliance & Authentication Requirements
Many email services now require proper sender authentication to prevent spoofing. If you use:
- A generic sender (like “WordPress”)
- A free email domain (@gmail.com, @yahoo.com)
Your emails are more likely to be blocked completely.
Key Takeaways
✔ Branding: Custom sender names build trust
✔ Deliverability: Proper sender info avoids spam folders
✔ Engagement: Recognizable senders get more opens
✔ Compliance: Many services block generic senders
In the next section, we’ll show you the easiest method to change this – using our recommended Email Sender Control plugin.

“After trying 5 different plugins, Email Sender Control was the only solution that worked perfectly out of the box without slowing down our membership site.” – Sarah K., WordPress Developer
Continue to Method 2: Manual Code Solution
Actionable Tip:
Set up a dedicated email address like notifications@yourdomain.com specifically for WordPress emails to keep them organized and maintain sender reputation. Most hosting providers include unlimited email accounts with your hosting plan.
Method 2: Change Sender Name via Code (Manual Developer Solution)
For WordPress developers and advanced users who prefer code-based solutions, you can modify the default email sender by adding custom PHP code to your site. While this method gives you complete control, it requires careful implementation to avoid breaking your site’s email functionality.
Understanding the WordPress Mail System
WordPress uses the wp_mail() function to handle all outgoing emails. Two key filters control the sender information:
wp_mail_from – Controls the email addresswp_mail_from_name – Controls the sender name
The Basic Code Implementation
Add this code to your theme’s functions.php file (preferably in a child theme):
// Change the default WordPress email address
add_filter('wp_mail_from', 'custom_wp_mail_from');
function custom_wp_mail_from($original_email_address) {
return 'noreply@yourdomain.com'; // Replace with your email
}
// Change the default WordPress sender name
add_filter('wp_mail_from_name', 'custom_wp_mail_from_name');
function custom_wp_mail_from_name($original_email_from) {
return 'Your Site Name'; // Replace with your sender name
}
Advanced Code Customizations
1. Conditional Sender Information
You can set different senders for different types of emails:
add_filter('wp_mail_from', 'dynamic_email_sender');
function dynamic_email_sender($email) {
if (strpos($_SERVER['REQUEST_URI'], 'wp-login.php') !== false) {
return 'security@yourdomain.com'; // For login-related emails
}
return 'notifications@yourdomain.com'; // Default email
}
2. Multisite Network Support
For WordPress Multisite installations:
add_filter('wp_mail_from', 'multisite_email_sender');
function multisite_email_sender($email) {
if (is_multisite()) {
$site = get_blog_details();
return 'noreply@' . $site->domain;
}
return $email;
}
Important Considerations When Using Code
⚠️ Always use a child theme – Direct edits to theme files will be lost during updates
⚠️ Test thoroughly – Broken email functionality can affect password resets, form notifications, etc.
⚠️ Consider email authentication – Ensure SPF/DKIM records are properly configured
Code Method vs Plugin Method Comparison
| Factor | Code Method | Email Sender Control Plugin |
|---|---|---|
| Difficulty | Advanced (requires coding) | Beginner-friendly |
| Flexibility | High (can create complex rules) | Moderate (UI-based options) |
| Maintenance | Requires manual updates | Automatic updates |
| Email Testing | Manual process | Built-in testing tool |
| Error Handling | None (fails silently) | Error logging and notifications |
| Performance Impact | Minimal | Very minimal (~1MB) |
When to Use the Code Method
- You’re a developer comfortable with PHP
- You need complex conditional sending logic
- You want to minimize plugin dependencies
- You’re building a custom WordPress solution
Troubleshooting Code Implementation
If emails aren’t sending after adding the code:
- Check for syntax errors – Use a PHP linter
- Verify filter priority – Some plugins may override your filters
- Test with WP_DEBUG enabled – Check for PHP notices/warnings
- Review server mail logs – Contact your host if needed
Pro Tip: Combine this method with SMTP configuration for best deliverability (covered in Method 3).
Security Best Practices
When implementing email changes via code:
- Never use admin@yourdomain.com – Create dedicated email addresses
- Sanitize all outputs – Prevent header injection attacks
- Validate email formats – Ensure RFC compliance
- Consider rate limiting – Prevent email abuse
// Secure email validation example
add_filter('wp_mail_from', 'sanitized_email_sender');
function sanitized_email_sender($email) {
$new_email = 'notifications@yourdomain.com';
if (filter_var($new_email, FILTER_VALIDATE_EMAIL)) {
return $new_email;
}
return $email; // Fallback to original if validation fails
}
Continue to Method 3: SMTP Configuration for Maximum Deliverability
Developer Note:
For production sites, consider creating a custom plugin for your email modifications rather than using functions.php. This makes your changes more portable and update-safe. A simple plugin only needs two files:
/wp-content/plugins/custom-email-sender/custom-email-sender.php/wp-content/plugins/custom-email-sender/readme.txt
Method 3: Configure SMTP for Better Email Delivery
While changing your sender information is crucial, using WordPress’s default PHP mail function often leads to deliverability issues. SMTP (Simple Mail Transfer Protocol) is the professional solution that ensures your emails reach the inbox every time.
Why SMTP is Essential for WordPress Emails
The default WordPress mail function:
- Has no authentication mechanism
- Often gets blocked by email providers
- Lacks proper email tracking
- Provides no bounce handling
Switching to SMTP solves these problems by:
✅ Authenticating your emails (prevents spoofing)
✅ Routing through reputable mail servers
✅ Providing detailed delivery reports
✅ Supporting TLS encryption for security
SMTP vs PHP Mail Deliverability Rates
| Email Service | PHP Mail Delivery Rate | SMTP Delivery Rate |
|---|---|---|
| Gmail | 58% | 98% |
| Outlook | 62% | 97% |
| Yahoo | 55% | 96% |
| Corporate | 48% | 99% |
Data from Email Deliverability Benchmark 2024
Step-by-Step SMTP Configuration
Option A: Using Your Hosting Provider’s SMTP
Most quality WordPress hosts include SMTP:
- Get SMTP credentials from your host (check their documentation)
- Install WP Mail SMTP plugin
- Go to WP Mail SMTP → Settings
- Select “Other SMTP” as mailer
- Â Enter:
- SMTP Host: mail.yourdomain.com (or host’s SMTP server)
- Encryption: TLS (recommended)
- Port: 587 (or 465 for SSL)
- Authentication: On
- Username/Password: Your credentials
- Â
Option B: Using Third-Party SMTP Services
Popular options with free tiers:
- SendGrid (100 emails/day free)
- Mailgun (1,000 emails/month free)
- Amazon SESÂ (62,000 emails/month free)
Configuration follows similar pattern with service-specific:
- SMTP servers
- API keys
- Port settings
Advanced SMTP Configuration Tips
1. SPF/DKIM/DMARC Records
Add these DNS records to improve deliverability:
; SPF Record
v=spf1 include:_spf.yourprovider.com ~all
; DKIM Record
mail._domainkey.yoursite.com. IN TXT "v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC..."
; DMARC Record
_dmarc.yoursite.com. IN TXT "v=DMARC1; p=none; rua=mailto:dmarc@yoursite.com"
Note: Above DNS record is an example, you can verify your DNS record with this or you can add new with this as an example, each provider has different value & name, So check with your SMTP provider.
2. Email Header Optimization
Add custom headers via SMTP plugin:
X-Mailer: YourSite Mail System
X-Origin: https://yoursite.com
List-Unsubscribe: <mailto:unsubscribe@yoursite.com>, <https://yoursite.com/unsubscribe>
Troubleshooting SMTP Issues
Common problems and solutions:
- Connection Timeouts
- Verify port numbers
- Check firewall settings
- Try alternative encryption (SSL/TLS)
2. Authentication Errors
- Regenerate SMTP passwords
- Verify username format (often full email required)
- Check service-specific requirements
3. Emails Still Going to Spam
- Warm up new IP addresses gradually
- Maintain clean recipient lists
- Monitor blacklists (mxtoolbox.com)
- Â
SMTP Monitoring and Maintenance
Essential tools for ongoing management:
