I think the way you are trying to send email using SmtpClient is not correct. using IMjmlServices you should try below way:

MjmlEmailService:

 public readonly IMjmlServices _mjmlServices;
 public EmailController(IMjmlServices _mjml) => (_mjmlServices) = (_mjml);


 public async Task MjmlEmailService()
        {
            var prehtml = "<mjml><mj-body><mj-container><mj-section><mj-column><mj-text>Hello From MJML Service!</mj-text></mj-column></mj-section></mj-container></mj-body></mjml>";
            var result = await _mjmlServices.Render(prehtml);
            SmtpEmailProcessor(result.Html);
        }

Note: Here you have to pass the result.Html from MjmlResponse interface which will be email body while SMTP request sent. Here it better to make two service separated because MjmlEmailService and SmtpClient has different concern.

SmtpClient:

public void SmtpEmailProcessor(string emailBody)
        {
            try
            {
                SmtpClient objsmtp = new SmtpClient("smtp.gmail.com", 587);
                objsmtp.UseDefaultCredentials = false;
                objsmtp.Credentials = new NetworkCredential("YourEmailId", "YourEmailPassword");
                objsmtp.DeliveryMethod = SmtpDeliveryMethod.Network;
                objsmtp.EnableSsl = true;
                MailMessage msg = new MailMessage("From Email", "To Email", "Subject: MJML Test", emailBody);
                msg.IsBodyHtml = true;
                objsmtp.Timeout = 50000;
                objsmtp.Send(msg);
            }
            catch (Exception ex) { }
        }

Hope above steps guided you accordingly.
