🔧 Setup Steps

1. Clone the repository

   git clone https://github.com/aa-maruf/EmailSender.MVC.git
   cd EmailSender.MVC

2. Configure Gmail App Password

   Google blocks direct SMTP logins with your normal password. To send emails using Gmail SMTP:

   • Enable 2-Step Verification in your Google Account: 👉 myaccount.google.com/security

   • Go to App Passwords, select Mail, and name it (e.g., ASP.NET App).

   • Google will generate a 16-digit app password (e.g., abcd efgh ijkl mnop).

   • Set it as an environment variable in your system:

     setx gmail_pass "your-app-password"

3. Update EmailSender.cs

   Replace the placeholder email with your Gmail:

   var username = "your_email@gmail.com";
   var fromEmail = "your_email@gmail.com";

4. Run EF Core Migrations

   In the Package Manager Console:

   Add-Migration InitialCreate
   Update-Database

5. Run the application

   dotnet run
