What is SMTP?
SMTP stands for "Simple Mail Transfer Protocol" it is the internet standard for sending emails. to comply with this standard, businesses use what's called an "SMTP server" to send out emails.
The SMTP server is also often used to identify you and your company which is critical for email communication. For this reason, LoginRadius allows you to use your company's SMTP server to send out emails which will ensure that those who receive your emails know that it truly came from your company and not from LoginRadius.
How LoginRadius utilizes your SMTP server
LoginRadius requires an SMTP server to send out emails to your users as part of the Email Workflow when they need to verify their email, when they do a password reset or simply to send them out a Welcome email once they register. As part of the workflow, LoginRadius simply pushes the emails that need to be send to your users through the SMTP Server and your SMTP server handles the sending.
