Your code example use pdf.text(), but in most situations, you want to export a html page with table(s) or image(s). The latest version jsPDF html PlugIn instead of addHtml(). Below is an code example using jsPDF html() and Web API.

Client side:

function emailHtml() {
    let pdf = new jsPDF('p', 'pt', 'a3'); // a4: part of the page is cut off?
    pdf.html(document.body, {
        callback: function (pdf) {
            let obj = {};
            obj.pdfContent = pdf.output('datauristring');
            var jsonData = JSON.stringify(obj);
            $.ajax({
                url: '/api/jspdf/html2pdf',
                type: 'POST',
                contentType: 'application/json',
                data: jsonData
            });
        }
    });
}

Note that the datauristring returned from pdf.html has a filename added to the string, filename=generated.pdf;. Also, SmtpClient is obsolete, consider to use MailKit instead.

[Route("[action]")]
[HttpPost]
public void Html2Pdf([FromBody] JObject jObject)
{
    dynamic obj = jObject;
    try
    {
        string strJson = obj.pdfContent;
        var match = Regex.Match(strJson, @"data:application/pdf;filename=generated.pdf;base64,(?.+)");
        var base64Data = match.Groups["data"].Value;
        var binData = Convert.FromBase64String(base64Data);

        using (var memoryStream = new MemoryStream())
        {
            var mail = new MailMessage
            {
                From = new MailAddress("[FromEmail]")
            };
            mail.To.Add("");
            mail.Subject = "";
            mail.Body = "attached";
            mail.IsBodyHtml = true;
            mail.Attachments.Add(new Attachment(new MemoryStream(binData), "htmlToPdf.pdf"));

            var SmtpServer = new SmtpClient("[smtp]")
            {
                Port = 25,
                Credentials = new NetworkCredential("[FromEmail]", "password"),
                EnableSsl = true
            };

            SmtpServer.Send(mail);
        }
    }
    catch (Exception ex)
    {
        throw;
    }
}
