Hi @William Dias ,
I suggest you can use try-catch to handle exceptions. You can include codes that may cause an exception in a try block. If you send email failed ,it could for loop to send the email.
You can refer to the following code:

public void DownloadEmail(string email)  
{  
    int tryAgain = 10;  
    bool failed = false;  
    do  
    {  
        try  
        {  
            failed = false;  
            var smtp = new SmtpClient();  
            var mail = new MailMessage();  
            const string mailBody = "Body text";  
            mail.To.Add(email);  
            mail.Subject = "Mail subject";  
            mail.Body = mailBody;  
            mail.IsBodyHtml = true;  
            smtp.Send(mail);  
        }  
        catch (Exception ex)  
        {                  
            failed = true;  
            tryAgain--;  
            var exception = ex.Message.ToString();  
            //Other code for saving exception message to a log.  
        }  
    }  
   while(failed  && tryAgain !=0)  
}
