How to Use SMTP Server to Send WordPress Emails?
WordPress relies on PHP’s built-in mail function to send emails by default, but this method can be unreliable, leading to emails getting flagged as spam or not delivered at all. Using an SMTP (Simple Mail Transfer Protocol) server is a more reliable and secure way to send WordPress emails. Here’s a guide on how to configure WordPress to use an SMTP server for sending emails.
Why Use SMTP for WordPress Emails?
SMTP is the standard protocol for sending email across the internet. Using SMTP in WordPress provides several benefits:
- Reliability: SMTP is more reliable than PHP’s mail function, reducing the chances of email delivery issues.
- Security: SMTP allows you to send emails through authenticated servers, improving security and reducing spam.
- Control: You can use your email provider’s SMTP server, giving you more control over how emails are sent and received.
1. Choose an SMTP Provider
To use SMTP with WordPress, you’ll need an SMTP server. Common SMTP providers include:
- Gmail/Google Workspace: Offers free and paid SMTP services.
- Microsoft Outlook/Office 365: Provides SMTP as part of its email services.
- Third-party SMTP Services: Providers like SendGrid, Mailgun, and Amazon SES offer scalable SMTP services for businesses.
Choose an SMTP provider that suits your needs and get the necessary credentials (SMTP server address, port, username, and password).
2. Install an SMTP Plugin for WordPress
To configure WordPress to use SMTP, you’ll need to install an SMTP plugin. Popular SMTP plugins for WordPress include:
Let’s use WP Mail SMTP for this guide:
- Install the Plugin: Go to “Plugins” > “Add New” in your WordPress dashboard. Search for “WP Mail SMTP,” then install and activate the plugin.
- Open the Plugin Settings: After activation, navigate to “WP Mail SMTP” in your WordPress dashboard.
3. Configure SMTP Settings in WordPress
Now that the plugin is installed, let’s configure the SMTP settings:
- SMTP Provider: In the WP Mail SMTP settings, select your SMTP provider from the list or choose “Other SMTP” for custom configurations.
- SMTP Server Address: Enter the SMTP server address provided by your email provider. For Gmail, it’s
smtp.gmail.com. - SMTP Port: Select the SMTP port. Common ports are 587 (for TLS/STARTTLS), 465 (for SSL), or 25 (for plain SMTP).
- Encryption: Choose the encryption type—typically, TLS for port 587 or SSL for port 465.
- SMTP Username and Password: Enter your SMTP username (usually your email address) and password. Some providers require an “App Password” for third-party applications, especially with Gmail.
- Sender Email and Name: Configure the email address and sender name that will appear in the emails sent from WordPress.
4. Test the SMTP Configuration
Once you’ve configured the SMTP settings, test the setup to ensure it’s working:
- Send a Test Email: In the WP Mail SMTP settings, look for the “Email Test” tab. Enter an email address to send a test email and click “Send Email.”
- Check Your Inbox: If the test email is delivered successfully, your SMTP configuration is working. If not, check the plugin’s error log for more information.
5. Troubleshooting SMTP Issues
If the test email doesn’t work, here are some common troubleshooting steps:
- Check Credentials: Ensure the SMTP username, password, server address, and port are correct.
- Use Correct Encryption: Double-check if you’re using TLS or SSL based on the port.
- Check Email Filters: Sometimes emails are blocked by spam filters. Check your spam or junk folder.
- Allow Less Secure Apps (for Gmail): If you’re using Gmail, ensure that you’ve allowed less secure apps or created an App Password in your Google account settings.
