Getting started with GemBox.Email

GemBox.Email is a .NET component that enables you to read, write, and convert email files (MSG, EML, and MHTML), or send and receive email messages (POP, IMAP, SMTP, and EWS) from .NET applications.

Requirements

GemBox.Email requires only .NET. It supports a wide range of .NET versions, as listed below:

.NET Standard 2.0+ (Android, iOS, Linux, macOS, Windows)
.NET Framework 3.5+ (Windows only)

Installation

Before you can use GemBox.Email, you need to install it in your project. The best way is by adding a GemBox.Email NuGet package via NuGet Package Manager in Visual Studio.

To install the package, you can follow the steps listed below. However, please note that this guide assumes you have already set up a Visual Studio project. If you haven't done that yet, you can refer to the official tutorial for guidance.

Right-click on the project's solution in the Solution Explorer and select 'Manage NuGet Packages for Solution'.
On the newly opened view, click the 'Browse' tab and search for GemBox.Email. Once found, click on 'Install'.
That is it. Once the installation finishes, you will be able to use the component in your code.

As an alternative, you can open the NuGet Package Manager Console (Tools -> NuGet Package Manager -> Package Manager Console) and run the following command:

Install-Package GemBox.Email

We also provide DLL and setup downloads on GemBox.Email's BugFixes page. Setup download links are at the bottom of the page, under the 'Global Assembly' section.

Usage

Once you have installed GemBox.Email, all you have to do is add the using directive and make sure you call the ComponentInfo.SetLicense method before using any member of the component. We suggest putting the call at the beginning of the Main() method.

The ComponentInfo.SetLicense requires a license key as a parameter. If you are using the component in a Free mode, use "FREE-LIMITED-KEY" as a license key, and if you have purchased a Professional license, use the key you got in your email after the purchase. You can read more about GemBox.Email's working modes on the Evaluation and Licensing page.

After that, you can write your application code for working with emails, like the code below. It shows how to create a MailMessage, set BodyText and BodyHtml, add some Attachments, and send it using SmtpClient.

        ComponentInfo.SetLicense("FREE-LIMITED-KEY");

        // Create new email message.
        MailMessage message = new MailMessage("sender@example.com", "receiver@example.com");

        // Add subject.
        message.Subject = "GemBox.Email getting started example";

        // Add HTML body 
        message.BodyHtml = 
            "<html><body>" +
            "<p>Hi 👋,</p>" +
            "<p>This message was created and sent with <a href='https://www.gemboxsoftware.com/email'>GemBox.Email</a></p>" +
            "</body></html>";

        // Add text body 
        message.BodyText =
            "Hi 👋,\n" +
            "This message was created and sent with GemBox.Email (https://www.gemboxsoftware.com/email)";

        // Add file as attachment.
        message.Attachments.Add(new Attachment("%#GemBoxSampleFile.pdf%"));

        // Create new SMTP client and send an email message.
        using (SmtpClient smtp = new SmtpClient("<ADDRESS> (e.g. smtp.gmail.com)"))
        {
            smtp.Connect();
            smtp.Authenticate("<USERNAME>", "<PASSWORD>");
            smtp.SendMessage(message);
        }
    }
