EmailSender.Graph

A lightweight C# library for sending emails using the Microsoft Graph API with support for:

  • Multiple recipients
  • HTML body content
  • File attachments

✨ Features

  • Send emails through a Microsoft 365 (Exchange Online) mailbox
  • Support for multiple To recipients
  • Optional file attachments
  • Uses Azure AD client credentials (daemon app authentication)

📦 Installation

Clone or install via NuGet (after publishing to NuGet.org or your internal feed):

dotnet add package EmailSender.Graph

Requires .NET Standard 2.1 or higher (.NET 6+ recommended)

🔧 Prerequisites

  • An Azure AD application with Mail.Send permissions (Application type)
  • Microsoft 365 mailbox (e.g., smtp_no_reply@yourdomain.com)
  • Registered application secret

🚀 Usage

using EmailSender.Graph; using Microsoft.Graph.Models;

var sender = new GraphEmailSender( tenantId: "your-tenant-id", clientId: "your-client-id", clientSecret: "your-client-secret", senderEmail: "smtp_no_reply@yourdomain.com" );

var attachments = new List<Attachment> { new FileAttachment { Name = "example.txt", ContentBytes = System.Text.Encoding.UTF8.GetBytes("Sample file content"), ContentType = "text/plain" } };

await sender.SendEmailAsync( subject: "Hello from Graph", body: "<p>This is a test email with <strong>HTML</strong> content.</p>", toRecipients: new List<string> { "user1@example.com", "user2@example.com" }, attachments: attachments );

📁 Attachment Model

Use the standard Microsoft Graph SDK FileAttachment model. Each attachment must include:

  • Name: filename
  • ContentType: MIME type (e.g., application/pdf, text/plain)
  • ContentBytes: file content as a byte array

✅ Permissions Required

Ensure your app registration has the following Microsoft Graph application permissions:

  • Mail.Send

Don't forget to grant admin consent after setting permissions.

🛠 Optional Improvements for Later

  • Add interface IEmailSender for abstraction
  • Add unit tests or integration test helpers
  • Support for Cc, Bcc, or sending on behalf of others
  • Automatic MIME type detection (e.g., via MimeKit or System.Net.Mime)
