After having tracked so many of my letters here are various ways of tracking your posts in India if it is being carried out by India Post. This how I gathered information over years.
Registered Post International
All international mails to and from India can be traced here
IPS Web Tracking: http://ipsweb.ptcmysore.gov.in/ipswebtracking/
Most of the international items coming to India by post (not Courier) have to pass through customs check at Mumbai. Only after the Mumbai office clears the item they will directed to the domestic location. If you see your item has been stuck at Mumbai customs you can call them and check:
If the item cost is more than $100 (excluding mail charges) you could attract customs duty.

You need to have patience. Pincodes are very important. The letters will come for sure. It might take almost a month sometimes but it would surely come. Unfortunately there is no one-point access for all these information. Purely based on my experience.
Hope this helps. Happy snail mailing.
