WordPress SMTP plugin with Stack Guard
Unlock links, two-factor email codes and security alerts are only useful if they arrive. Stack Guard records the last email failure, recognises the common sending plugins, and tells you when the server's own mail is all you have.

Questions
SMTP plugins and Stack Guard: questions
Why does a security plugin need an SMTP plugin?
Unlock links, two-factor codes and alerts are sent by email. Without a proper sending service, many of them never arrive.
Which SMTP plugin should I use?
Any of the common ones works. Stack Guard recognises WP Mail SMTP, FluentSMTP, Post SMTP and several others, and only cares that mail actually arrives.
