MailMerge class is very flexible and can be used for creating of e-mail messages based on a template and data from any source.

However, if such flexibility is not needed and the source of the data is a database, then it's easier to use Smtp.SendMailMerge method.

This sample defines a template and generates 3 e-mail messages based on it. The template includes both static fields (for instance, From field remains the same for all e-mails in the series) and dynamic patterns which are replaced with actual values for every e-mail generated. Two attachments are added to each message: one static and one pattern-based.
// To use the code below, import these namespaces at the top of your code.
using System.Collections;
using System.Collections.Specialized;
using MailBee;
using MailBee.Mime;

// The actual code (put it into a method of your class)

// Create an object to store the list of e-mail addresses and friendly names...
StringDictionary sd = new StringDictionary();

// ...add populate it with some values.
sd.Add("", "John Doe");
sd.Add("", "Kathy");
sd.Add("", "Mark");

// Set up an e-mail template.
MailMessage msg = new MailMessage();
msg.To.AsString = @"""%%NAME%%"" <%%EMAIL%%>";
msg.From.Email = "";
msg.Subject = "Hello, %%NAME%%.";
msg.BodyPlainText = @"Hello, %%NAME%%. Your e-mail is %%EMAIL%%.";
msg.BodyHtmlText = @"<html>
Hello, <b>%%NAME%%</b>. Your e-mail is <i>%%EMAIL%%</i>.
Attached File: <font color=""red"">%%FILENAME%%</font>
<img src=""cid:123456"" alt="".NET"">

// The template also includes the attachment which is common for all e-mails in the series...
msg.Attachments.Add(@"C:\Docs\image17b.gif", "logo.gif", "123456");

// ... and the attachment which is unique for each e-mail.

// Create array of actual filenames which will substitute %%FILENAME%% pattern in merged e-mails.
string[] strArrays = {"image1.jpg", "image2.gif", "image3.gif"};

// Perform actual mail merge and save the resulting e-mails to disk.
int i = 1;
foreach (DictionaryEntry de in sd)
    msg.Merge.Replace(@"%%NAME%%", (string)de.Value);
    msg.Merge.Replace(@"%%FILENAME%%", strArrays[i-1], MailMergeTargets.BodyHtmlText);
    msg.Merge.Replace(@"%%EMAIL%%", (string)de.Key, MailMergeTargets.Recipients |
        MailMergeTargets.Subject | MailMergeTargets.BodyHtmlText | MailMergeTargets.BodyPlainText);

    msg.Merge.MergedMessage.SaveMessage(string.Format(@"C:\Temp\merge{0}.eml", i));
