How to send emails using Gmail SMTP settings
Introduction
In this article, I will explain the configuration method for sending emails from an application using Gmail.
While there are several free email servers available, I found it more convenient to easily set up Gmail when performing test transmissions, so I have compiled this as a memo for myself.
Settings
1. Set up 2-Step Verification
First, set up 2-Step Verification from Security.
Enable the 2-Step Verification process
2. Set up App Passwords
From the bottom of the 2-Step Verification page, click on "Create App Password >".
Any app name can be entered, then click "Create".
If the App Password option does not appear, please configure it from here while logged into your account.
3. Save the generated App Password
Copy and save the App Password.
4. Gmail SMTP settings method
By setting the following information in your environment variables, you can configure email sending using Gmail. Please add this information to your .env file.
| Email Server | smtp.gmail.com |
| Port Number | 587 |
| Sender Email Address | Gmail email address |
| SMTP Username | Username (the part to the left of the @ in your Gmail address) |
| Password | The App Password you just saved |
Conclusion
In this article, I introduced the setup procedures for sending emails from an application using Gmail.
Since Gmail is familiar to many and has a low barrier for environment setup, it is very convenient for testing purposes or small-scale applications.
I compiled this as a personal memorandum, but I hope it will be helpful to others setting up email transmission in similar situations.
