  • sorry I’m new kkk

  • Wellington I don’t know if it helps, but try to put all texts inside tags, like asism: <p>texto</p>. P is a block element and theoretically should throw the next P to the bottom line.

Follow a treatment I’ve used a few times.

    string conteudoTexto =  text_mensagem.Text.Replace(System.Environment.NewLine, "<br />");

    // Conteudo do corpo do e-mail
    mailMessage.Body = conteudoTexto;
