Once your Themelia Pro mail configuration is setup, you may use the following code in your application to quickly send mail, where each argument is of type System.String.
Themelia.Mail.NotificationFacade.Send(from, ToString, subject, body);
There are multiple overloads for this method, three of them are the most commonly used:
public static void Send(String from, String to, String subject, String body);
public static void Send(String from, String to, String subject, String body, Boolean isHtml);
public static void Send(String from, String to, String subject, String body, DateTime datetime, String cc, String bcc, Boolean isHtml, List<string> attachmentPaths);
