Mailkit C# (How it Works For Developers)

How to Use MailKit

For any business looking to level up their marketing, MailKit is a comprehensive and powerful tool for managing email and SMS communications. For example, MailKit allows you to build templates and automate email generation from a chosen data source, meaning you can send frequent, updated emails without having to manually build or send your messages.

In this guide, we’ll show you how to install and get started with using MailKit, as well as how to integrate it with IronPDF to create a powerful email and PDF-generation program.

What is MailKit?

MailKit is an open-source project which has become an essential tool in .NET app development. It’s a comprehensive email framework which supports sending and receiving emails through SMTP and IMAP protocols. It enables developers to interact with mail servers easily, send HTML emails, and manage security settings, proving crucial for .NET applications requiring email functionalities.

IronPDF allows for generating, rendering, and manipulating PDF documents within .NET apps. It simplifies converting HTML templates to PDFs and creating intricate documents, making it an ideal tool for managing PDFs with web-based data.

Getting Started with MailKit

Installing MailKit in Your Project

To start using MailKit in your application, you need to install the MailKit package. This can be done via NuGet, a package manager for .NET. Here's how you can do it:

• Open your C# project in Visual Studio
• Navigate to the Solution Explorer, right-click on your project, and select Manage NuGet Packages
• Search for 'MailKit' in the NuGet Package Manager and install it.

Setting Up MailKit for Email Operations

Once installed, you can begin setting up MailKit in your application. This involves configuring the SMTP server for sending emails and, optionally, the IMAP server for receiving emails. Here's a basic setup:

using MailKit.Net.Smtp;
using MimeKit;
public class EmailService
{
   public void SendEmail(string recipientAddress, string subject, string body)
   {
       var message = new MimeMessage();
       message.From.Add(new MailboxAddress("Your Name", "your@email.com"));
       message.To.Add(new MailboxAddress("", recipientAddress));
       message.Subject = subject;
       message.Body = new TextPart("plain")
       {
           Text = body
       };
       using (var client = new SmtpClient())
       {
           client.Connect("smtp.server.com", 587, false);
           client.Authenticate("your@email.com", "yourpassword");
           client.Send(message);
           client.Disconnect(true);
       }
   }
}

using MailKit.Net.Smtp;
using MimeKit;
public class EmailService
{
   public void SendEmail(string recipientAddress, string subject, string body)
   {
       var message = new MimeMessage();
       message.From.Add(new MailboxAddress("Your Name", "your@email.com"));
       message.To.Add(new MailboxAddress("", recipientAddress));
       message.Subject = subject;
       message.Body = new TextPart("plain")
       {
           Text = body
       };
       using (var client = new SmtpClient())
       {
           client.Connect("smtp.server.com", 587, false);
           client.Authenticate("your@email.com", "yourpassword");
           client.Send(message);
           client.Disconnect(true);
       }
   }
}

Setting Up SMTP and IMAP Servers

Configuring SMTP Server for Sending Emails

To send emails using MailKit, you need to configure an SMTP server. The SMTP (Simple Mail Transfer Protocol) server is responsible for sending your emails to the intended recipients. Here's a guide to setting up an SMTP server in your application:

• Choose an SMTP Service: You can use a popular email service like Gmail, Outlook, or any other that provides SMTP support
• SMTP Server Details: Obtain the SMTP server address, port number, and the necessary authentication details (username and password) for your chosen email service

Example: SMTP Configuration for Gmail

Here's an example of configuring an SMTP client to send emails using Gmail's SMTP server:

using (var smtpClient = new SmtpClient())
{
   smtpClient.Connect("smtp.gmail.com", 587, MailKit.Security.SecureSocketOptions.StartTls);
   smtpClient.Authenticate("yourgmail@gmail.com", "yourpassword");
   // Send your message here
   smtpClient.Disconnect(true);
}

using (var smtpClient = new SmtpClient())
{
   smtpClient.Connect("smtp.gmail.com", 587, MailKit.Security.SecureSocketOptions.StartTls);
   smtpClient.Authenticate("yourgmail@gmail.com", "yourpassword");
   // Send your message here
   smtpClient.Disconnect(true);
}

Setting Up IMAP Server for Receiving Emails

To receive and read emails, configure an IMAP (Internet Message Access Protocol) server. IMAP allows you to access and manage your emails directly on the email server, making it a popular choice for email clients.

Connecting to an IMAP Server

To connect to an IMAP server, you'll need the server address, port number, and account credentials. Here’s a basic connection setup:

using (var imapClient = new ImapClient())
{
   imapClient.Connect("imap.gmail.com", 993, true);
   imapClient.Authenticate("yourgmail@gmail.com", "yourpassword");
   // Access and manage your inbox here
   imapClient.Disconnect(true);
}

## Advanced Email Handling and Building a Complete Email Application

### Integrating Advanced MailKit Features

Once you've set up the basic functionalities for sending and receiving emails with MailKit, it's time to explore its advanced capabilities.

These include handling HTML emails, using HTML email templates, attaching files, and implementing client-side sorting and searching within the email inbox.

```cs
var message = new MimeMessage();
message.From.Add(new MailboxAddress("Your Name", "your@email.com"));
message.To.Add(new MailboxAddress("", "recipient@email.com"));
message.Subject = "Your Subject Here";
var builder = new BodyBuilder
{
   HtmlBody = @"<html><body><h1>Hello, World!</h1></body></html>"
};
message.Body = builder.ToMessageBody();

using (var imapClient = new ImapClient())
{
   imapClient.Connect("imap.gmail.com", 993, true);
   imapClient.Authenticate("yourgmail@gmail.com", "yourpassword");
   // Access and manage your inbox here
   imapClient.Disconnect(true);
}
