What Is Other SMTP in Master SMTP?
Other SMTP in Master SMTP lets you connect your WordPress website to any mail service that provides standard SMTP credentials. Instead of using a built-in mailer integration, you can enter the SMTP details manually and send your website emails through your own mail server or email provider.
This option is useful when your hosting provider, cPanel email account, business email service, or private mail server gives you SMTP settings such as SMTP host, port, encryption type, username, and password.
In simple terms, Other SMTP is the flexible option for custom email services that are not listed as a dedicated mailer inside Master SMTP.
In this guide, we will use a cPanel email account as an example, but the same setup steps also apply to many other hosting providers and email services that support SMTP.
Before you start, make sure you have your SMTP host, SMTP port, encryption type, username, and password ready. You will enter these details later in the Master SMTP connection settings.
Set Up Custom SMTP Settings Using cPanel Email
In this example, we will use a cPanel email account to set up Other SMTP in Master SMTP. cPanel is a common hosting control panel, and it provides the SMTP details you need, such as the mail server, port, encryption type, username, and password.
If you do not use cPanel, you can still follow the same general steps using the SMTP settings provided by your email hosting company or mail service.
Check Your Email Deliverability Status
In cPanel, go to the Email section and click Email Deliverability.
Make sure the domain you want to use shows Valid in the Email Deliverability Status column before continuing.
If you see a warning such as Problems Exist (DMARC, DKIM, and SPF), click Manage to review and fix the missing or invalid email records before continuing.
If cPanel shows any email deliverability problems, review the listed issues and apply the recommended fixes. If you are not sure how to fix them, contact your hosting provider and ask them to correct the email deliverability records for your domain.
Set Up Mail Client in cPanel
After confirming your email deliverability status is valid, go back to your email account settings in cPanel and open the Mail Client setup page for the email address you want to use. This page shows the SMTP details you will need for the Custom SMTP settings in Master SMTP.
In cPanel, go to the Email section and click Email Accounts.
Find the email account you want to use for SMTP, then click Connect Devices.
On the Mail Client setup page, look for the Mail Client Manual Settings section. In most cases, use the Secure SSL/TLS Settings values and keep the SMTP details ready for the next step.
Set Up Other SMTP in Master SMTP
In your WordPress dashboard, go to Master SMTP > Connections, then click Create New Connection.
Configure Connection
In the Configure Connection section, fill out the Connection Details fields:
Connection Details: Enter a name for this connection. This is only for you, recipients will not see it.
Default From Email: The email address used when an outgoing email does not define a From Email.
Force From Email: If enabled, this From Email will be used for all emails, even if the email has a different From Email.
Default From Name: The name used when an outgoing email does not define a From Name.
Force From Name: If enabled, this From Name will be used for all emails, even if the email has a different From Name.
Default Reply-To Email: The Reply-To address used when an outgoing email does not define a Reply-To Email.
Force Reply-To Email: If enabled, this Reply-To Email will be used for all emails, even if the email has a different Reply-To Email.
In the Choose a Mailer section, select Other SMTP from the grid mailer list.
Configuration
In the Custom SMTP Settings section, start with the Configuration fields.
Enter your SMTP Hostname exactly as shown in your email account setup. In this example, it is mail.yourdomain.com.
Then enter the SMTP Port. For cPanel email accounts using secure SSL/TLS settings, this is commonly 465.
General Settings
Next, configure the General Settings options.
Return Path: Enable this if you want non-delivery notifications to be sent back to the sender address. You can leave it disabled unless you specifically want bounce notices handled this way.
Auto TLS: Keep this enabled if your mail server supports TLS. This is recommended in most cases.
Encryption: Select the encryption method that matches your email provider settings. For most modern SMTP servers, TLS is recommended. If your cPanel mail settings specifically use SSL on port 465, choose SSL instead.
Authentication
In the Authentication section, enable authentication if your SMTP server requires a username and password. This is the standard setup for most cPanel email accounts.
For Authentication Username, enter the full email address of the mailbox you want to use.
For Authentication Password, enter the password for that email account.
Save Connection
If you want this to be your main sending connection, enable Make this the default connection. Then click Save Connection.
The connection will be added to the Connections list, and you should see Connection saved. at the top of the window.
Note: The free version allows you to add only one connection. If you need multiple connections, Conditional Routing, and many other features, you should purchase the Master SMTP Pro.
Test SMTP Connection
After saving your SMTP connection, it is recommended to send a test email to make sure everything is working correctly. This helps confirm that your connection settings have been entered properly and that your site can send emails successfully through SMTP.
