By default, WordPress uses the PHP Mail function to send emails. However, it is better to use SMTP, as it is more reliable and allows you to send emails from a third-party mail service. To make the process easier, there are several plugins available that can help you configure your WordPress site to use SMTP. The WP Email SMTP plugin is free and easy to use, and allows you to connect to SMTP services such as Amazon SES, MailGun, MailGet, SendGrid, MailJet and more.
The MailerSend plugin for WordPress also allows you to send emails using a reliable SMTP server. If you're not sure how to configure your WordPress SMTP settings, contact your email provider and WordPress. By default, WordPress uses the PHP mail () function to send automated emails such as registration confirmations, lost passwords or form notifications. If you're having trouble sending emails from WordPress, you'll need to debug your email configuration settings or contact the technical support team of your WordPress hosting provider.
You can also use a third-party WordPress plugin or write your own code in a custom WordPress plugin. If the first three troubleshooting options don't solve the problem with sending WordPress emails, there may be a conflict between WordPress plugins. The CreativeMinds team has created the Mail SMTP Gateway plugin for WordPress which allows users of all levels to successfully send emails from their WordPress site. Finally, if you want WordPress to send even more transactional emails, you can use the free Better Notifications for WP plugin to create personalized notification emails.
Just make sure to pair them with a sending service via MailPoet or an SMTP plugin from WordPress.
