I need help to clarify these patterns.
1.I have recieved the mail.
2.I had recieved the mail.
3.I recieved the mail.
I am wondering what differences among these three tense are, since they all mean the action is happened, but when to use which tense is proper and correct? I read the grammar book, though, I still feel mess.

1. I have recieved the mail.- this sentence is Present Perfect Tense   - in this tense the action started in the past and has never ended  
2. I had received the mail - this is the Past Perfect tense - In this tense the action started in the past, went on for sometime and ended in the past  
3. I recieved the mail - simple past tense - the action started and ended in the past

So here are the differences I hope I have helped you in some way.Have a nice day!
