3. Configure Environment Variables

Create a .env.local file in the root of your project with the following variables:

2. Navigate to Security
3. Under "Signing in to Google," select "App Passwords"
4. Generate a new app password for "Mail" and "Other (Custom name)"

To run the app in development mode, use:

npm run dev

The application should now be accessible at http://localhost:3000.

   • Recipient email addresses (comma-separated)
   • Email subject
   • Email body
3. Fill in the required information
4. Click the "Send Emails" button to start the bulk email process
5. The application will send personalized emails to each recipient and display the results

Important Notes

• The application uses Gmail's SMTP server, which has a limit of 500 emails per day for free accounts
• Emails are sent in batches to avoid rate limiting (20 emails per minute)
• Make sure your Gmail account has "Less secure app access" enabled or use an app password as described above

If you encounter any issues with authentication or sending emails, double-check your Gmail app password and ensure it's correctly set in the .env.local file.
