What is SMTP?

SMTP stands for Simple Mail Transfer Protocol which is an industry-standard for sending emails. With proper SMTP configuration and authentication, the email deliverability rates increases. There is a constant battle between popular email clients like Gmail, Yahoo, and Office 365. All they look for is whether an email is originating from the location it claims to be originating from.
If the proper authentication isn’t there, then emails either go in the SPAM folder or don’t get delivered at all. This is a case with a lot of WordPress sites because, by default, WordPress uses the PHP mail function to send emails generated by WordPress or any contact form plugin like WPForms.
And when you use any one of the built-in SMTP mail provider integrations, the emails are sent using the provider’s direct API. Meaning even if your web host is blocking SMTP ports, your emails still get send successfully.
