Check your email client's spam folder—some spam filters are more aggressive than others in identifying spam. Emails from Imonggo may be sorted in the spam folder by chance.
Wait for 24 hours to receive the email. Either your mail client or Imonggo's mail client may be overloaded and your emails may need sometime before they get sent or received.
If you still haven't received the emails, please try to use another email address. Your email address may be blocking emails from Imonggo.
