本示例使用单个模板和数据库发送多封电子邮件。

对于每个消息,从数据库中获取的实际值将替换模板中的占位符。因此,所有电子邮件将具有相同的外观,但仍将是个性化的。本示例代码使用ADO的Connection对象连接到MS Access数据库。然后,ADO的Recordset对象被“电子邮件”表中的值填充。该表的每个记录然后用于生成单个电子邮件。

该代码假定数据库位于C:\ Docs \ simple_merge.mdb文件中,并且“电子邮件”表如下所示:



  • 注意1:该示例通过单个SMTP连接发送所有电子邮件(这提供了最佳性能)。但是,某些SMTP服务器只允许通过同一连接发送少量电子邮件。
  • 注意2:为减少批量发送应用程序的响应时间,您可以告诉MailBee在后台发送电子邮件。
