SPUtility.SendEmail truncates your message body
Use this instead to send longer emails from SharePoint: MailMessage message = new MailMessage(); message.From = new MailAddress(list.ParentWeb.Site.WebApplication.OutboundMailSenderAddress); message.To.Add( new MailAddress("email@email.com)); message.Subject = "Subject"; message.Body = "Body"; SmtpClient smtpClient = new SmtpClient(SPContext.Current.Site.WebApplication.OutboundMailServiceInstance.Server.Address); smtpClient.Send(message);
