SMTP is the easiest SMTP plugin for WordPress. It allows you to configure an SMTP server to send email from your website. SMTP enhances the default WordPress mail (“wp_mail”) function by letting you connect to a remote SMPT server to send an email instead of doing it from your web server. This reduces heavy load from your server and increases email deliverability.
SMTP Settings
You will need to configure your SMTP server related information in order to send email from your website. In order to access the settings menu go to “Settings->SMTP” from your admin dashboard.
The settings menu comes with three separate tabs – General Settings, Test Email & Server Info.
General Settings

Your outgoing mail server which will be used for sending email (e.g. smtp.gmail.com).

Enable/Disable SMTP authentication when sending an email (Supported values: True/False).
SMTP Username

Type of Encryption
The encryption which will be used for sending an email (Supported values: TLS/SSL/No Encryption. TLS is recommended).
SMTP Port
The port which will be used when sending an email (587/465/25). If you choose TLS the port should be set to 587. For SSL use port 465 instead.
