Setup Google Workspace as SMTP

---

An SMTP Server is an application that allows your device or server to receive and send Electronic Mails (e-mail) to various email receivers and senders. SMTP stands for Simple Mail Transfer Protocol and it is a standard for sending emails. They use a wireless carrier to route text/push messages to the inbox of email applications.

By default, miniOrange provides and uses its own SMTP Server to send OTPs to users. If you have a custom SMTP Server configured, you can use the same to send Emails from your miniOrange account. Check out our list of Supported SMTP Servers.

miniOrange IDP allows you to configure Google Workspace as SMTP email provider hence giving you freedom to manage, monitor, and troubleshoot your email communications.
