SMTP Settings Overview

Unlike our other options which use APIs to allow this setup information to be stored with Google, SendGrid, or Mailgun, the Other SMTP option in WP Mail SMTP requires this setup information to be stored directly on your site.

Below, we’ll go into more detail on each of the fields required to set up an “Other SMTP” option in WP Mail SMTP.

SMTP Host
This is the the address to the host’s SMTP server.

SMTP Port
The most common ports are 587 and 465, however hosts can and do change these. It’s not uncommon for web hosts to block these ports, so before you begin it’s always good to verify with your web host that the required port is open. If closed, most of the time your hosting provider can open it for you.

Encryption
SSL and TLS are the most widely used encryptions. If your email provider offers both, we recommend TLS. It is worth noting that usually TLS encryption is used with port 587, while SSL is used with port 465.

Authentication
Modern email providers require authentication. Disabling it may be needed for local development or other edge case scenarios, however most providers need this turned on.

SMTP Username
Your username is typically your email address for the email provider; e.g. john@gmail.com or john@hotmail.com. Some providers such as AOL require the non-email format; e.g. if your email is john_doe@aol.com your username would be john_doe.

SMTP Password
This is your email account password. Please note although the password is not viewable in the settings, it is still stored in the database as plain text. This is required since establishing the SMTP connection requires sending the password in plaintext.

With this in mind, we highly recommend you set up your password in your WordPress configuration file, wp-config.php for improved security. You can easily add this code using SFTP or file manager if using cPanel.

Here’s the code you’ll need to add:

define( 'WPMS_ON', true );
define( 'WPMS_SMTP_PASS', 'your_password' );

Then, you’ll just need to replace your_password with your actual password. When you save the file and refresh your SMTP settings page, you should see the Password field is now slightly greyed out and disabled since it’s no longer being used.

SMTP Settings for Popular Providers

When filling out the fields mentioned above, the settings you’ll need will depend on your email provider.

Here are the SMTP settings you’ll need for the most popular email providers:

cPanel Settings

Host: mail.yourdomain.com
Port: IMAP Port: 993 if using POP3 Port: 995
Username: Your cPanel email address (e.g. user@yourdomain.com)
Password: Your cPanel email password
Encryption: TLS

IMAP, POP3, and SMTP require authentication

Gmail / G Suite SMTP Settings

Host: smtp.gmail.com
Port: 587 (or 465 using SSL encryption)

Please note we recommend using the built in Gmail integration instead of the SMTP method. If you use SMTP, don’t forget to enable less secure apps.
