WordPress comes with a default PHP mailer script and sending emails from WordPress often doesn’t work. This module allows you to set up and use a custom SMTP server to send your emails.
Activate the SMTP Mail Module
In the Admin Optimizer page, click to enable the SMTP Mail module. Press Save Changes to save the changes.

Configure the SMTP Mail Module
- Navigate to Admin Menu → Admin Optimizer → SMTP Email
- Enter the following details required for the SMPT mailer to work:
- SMTP server: URL of the SMTP server
- SMTP Authentication: server authentication. This should be enabled in most cases.
- SMTP Encryption: either TLS or SSL.
- SMPT Port: is usually 465 for SSL or 587 for TLS.
- SMTP Username: your authentication username
- SMTP Password: your authentication password
- Send From: set the default name in the From field of the email
- Email From: set the default email in the From field of the email.

Test SMTP Mail Module
After you have added the SMTP details, enter an email in the Send a Test Email field and click Send Test Email. This will send a test email to the stated email address. If the SMTP details work, you will see a message “Email sent successfully”.
