GoSMTP – Free and lightweight

GoSMTP is a lightweight SMTP plugin with a clean setup for popular mailers and basic email logging at no cost. Against FluentSMTP, it aims for a minimal, easy configuration experience.

SMTP Mailer – Basic mail sending

SMTP Mailer is a minimal plugin that simply routes WordPress mail through an SMTP server with a short list of settings.
