Before getting started, you’ll need to ensure WP Mail SMTP is installed and activated on your WordPress site and that you’ve verified your license.
What Is a Backup Connection?
A Backup Connection in WP Mail SMTP is used as an additional connection to ensure emails from your website get delivered. If your Primary Connection fails to send emails, the Backup Connection will be used as a substitute to improve email deliverability.
Note: Before setting up a Backup Connection, you’ll need to add at least one additional connection to your website.
Setting Up a Backup Connection
Once you’ve added an additional connection, go to WP Mail SMTP » Settings to access the plugin’s settings page.
On the General tab, scroll down to the Backup Connection section.
Here, you’ll be able to choose any additional connection you’ve previously configured.
Note: You can add many additional connections in WP Mail SMTP. But you’ll be able to choose only one of them as a Backup Connection.
Go ahead and choose the one you’d like to use as a Backup Connection.
Be sure to click Save Settings after making your selection.
Testing the Backup Connection
After you’ve configured additional connections, you’ll be able to choose between the Primary Connection and other additional connections when sending a test email.
We’ll send a test email using the Backup Connection we configured to ensure it works properly.
To send a test email, go to WP Mail SMTP » Tools and select the Email Test tab.
In the Send To box, enter an email address whose inbox you have access to.
Under Connection, you’ll see all the mailers you’ve configured on your website. Go ahead and choose the option you selected as a Backup Connection.
Next, choose whether to send a plain text or HTML email. Unless you know you’ll only be sending plain text emails, we recommend leaving the HTML setting toggled ON.
Finally, click on Send Email to send your test email with the Backup Connection.
If the test email delivers successfully, the Backup Connection is working.
Your website will use this option whenever the Primary Connection fails to send an email.
That’s it! Now you know how to configure a Backup Connection in WP Mail SMTP.
