Here’s a detailed tutorial for connecting to Google’s SMTP server from SMPP Center‘s application. This tutorial includes steps to set up the necessary configurations, such as enabling two-factor authentication, generating an app password, and using the correct SMTP details. Each step is accompanied by a detailed explanation.


Step 1: Login to Your Google Account

  1. Open a web browser and navigate to https://accounts.google.com.
  2. Enter your Gmail credentials (email and password) to log in.

Step 2: Access Google Account Settings

  1. After logging in, click on your profile picture in the top-right corner.
  2. Click “Manage your Google Account.”

Step 3: Navigate to Security Settings

  1. In the left-hand menu, click on “Security.”
  2. Under the “Signing in to Google” section, ensure that Two-Factor Authentication is enabled.

Step 4: Enable Two-Factor Authentication

  1. If two-factor authentication (2FA) is not already enabled:
    • Click “2-Step Verification” and follow the instructions to set it up. This usually involves adding a phone number and verifying it via SMS or a phone call.
  2. Once enabled, your account is more secure and you can proceed to generate an app password.

Step 5: Generate an App Password

  1. In the “Security” section, scroll down to “Signing in to Google” and click “App Passwords.”
  2. Authenticate yourself using your account password or 2FA prompt.
  3. In the “App Passwords” page:
    • From the “Select app” dropdown, choose “Mail”.
    • From the “Select device” dropdown, choose “Other (Custom name)” and enter a name for your application (e.g., “SMTP Integration”).
  4. Click “Generate.”
  5. Copy the app password that is generated (a 16-character code). You’ll need this for your SMTP configuration.

Step 6: SMTP Configuration

Now that you have your app password, you can configure your SMPP software application to use Google’s SMTP server. Use the following details:

ParameterValue
SMTP Hostsmtp.gmail.com
SMTP Port587 for TLS, 465 for SSL
EncryptionTLS or SSL (depending on your application settings)
UsernameYour full Gmail address (e.g., youremail@gmail.com)
PasswordThe app password you generated in Step 5

Step 7: Test the SMTP Connection

  1. Use the configuration settings above in your SMPP Software application.
  2. Send a test email to ensure that the SMTP connection works correctly.
  3. If there are issues, double-check the app password and port settings.

Troubleshooting Tips

  • Authentication Failed: Ensure 2FA is enabled and you’re using the app password, not your Gmail password.
  • Blocked Sign-in: Check your Google account security settings for suspicious activity. Approve the activity if prompted.
  • Firewall Restrictions: Ensure your hosting provider or local network allows outbound connections on SMTP ports 587 or 465.
