WP Mail SMTP Pro is one of the best and most widely used email delivery plugins among several similar plugins. It’s not without reason, this plugin is easy to use and has many options for handling email issues. As a GPLShare author, I’ll explain the details so you understand before using it.
GPLShare friends! The WP Mail SMTP Pro plugin is now available in our catalog and can be downloaded for free with membership. This is a world-renowned SMTP (Simple Mail Transfer Protocol) plugin, created to address email deliverability failures on WordPress.
Why Does WordPress Need WP Mail SMTP Pro?
You probably already know that by default WordPress uses its function called wp_mail() to send emails like WooCommerce order confirmations, password reset links or messages from contact forms. This function actually uses the built-in PHP mail() function from your hosting server.
As a beginner you often face problems with emails not being delivered. You don’t know why or how to fix it right?
The real issue is the hosting server setup, for example:
- Emails sent through PHP
mail()don’t have a digital signature. - Email services like Gmail, Yahoo, Outlook and others have rules. Emails without verification are sure to end up in the Spam or Junk folder or they might be blocked or not sent at all.
- Also if you are, on hosting it often limits how many emails you can send and blocks SMTP ports to stop spam from other users on the same server.
Now you understand, this is why the WP Mail SMTP Pro plugin is needed.
Technical Solutions for WP Mail SMTP Pro
WP Mail SMTP Pro bypasses the PHP mail() function and reconfigures WordPress to use an authenticated SMTP protocol, or leverage the API of a third-party email service provider.
What mailer integrations are supported? I’ll explain them here:
- Secure API Integrations. SendLayer, Brevo (formerly Sendinblue), Mailgun, SendGrid, Postmark, SparkPost.
- Enterprise Solutions. Amazon SES, Google Workspace, Microsoft 365.
- You can also use Custom SMTP to connect your own SMTP server or premium hosting using SSL/TLS encryption.
Some Key Features (Advanced Features)
This Pro version we’re discussing isn’t just an ordinary SMTP route changer, it brings better email management features. Here are the details:
1. Email Log & Analytics
Keep in mind… this doesn’t just record sent emails, this feature also provides telemetry in:
- Delivery Status to find out whether an email is in Sent, Failed, or Delivered status.
- Open & Click Rates to find out whether your emails are opened and the links inside them are clicked.
- Export & Print Feature to export logs to CSV/Excel format.
2. Email Controls
WordPress often sends automatic emails you don’t need, for example: every time there’s a new comment, an automatic plugin update, or a new user registration. Now you can turn off specific notifications to save your email sending quota.
3. Smart Email Routing
This is one of the most useful features, because you can create conditional logic.
Here are the details:
- For example, if an email comes from a specific form, you can choose to send it using a specific provider.
- Another example: if an email is a regular newsletter, send it via Brevo or Mailgun.
4. Email Alerts & Failover
You can send instant notifications via Slack, Twilio SMS, or a backup email if an important email fails to send.
If your primary SMTP provider experiences downtime, with Backup Connection the plugin will automatically reroute sending to the backup SMTP provider you’ve already configured.
