When you’re using something like Easy WP SMTP, what you’re doing is configuring things so that wp_mail() sends using your validated SMTP account rather than the generic mailer on the web server.
The a common confusion and misconception is that you are using SMTP OR wp_mail(). Actually what you’re doing is changing what wp_mail() is using to send.
So you’re still using wp_mail(). Properly configured, anything going through wp_mail() will be going through your SMTP account.
