Is it possible to track emails to the extent that we get counts for "READ","DELETED","SOFT BOUNCE","HARD BOUNCE"? -
the title being self explanatory, add points it.
1.firstly, possible track these (read,deleted,soft bounce,hard bounce) without using third party api? 2. if no, third party services provide same ?

, can me "no.of reads/forwards", not deleted.
anybody in ?
there number of things can detect own software , no third party, though don't know how map onto categories list:
- tracking images , links, said (read).
- no mail server take message, e.g there might not mx record domain or mailserver ip might blocked dnsbl (maybe mean hard bounce?)
- mail server response codes. might tell example:
- your email rejected because mailbox on capacity etc (probably soft bounce)
- rejected because it's spam (probably hard bounce)
- greylisted or (probably soft bounce)
there nothing can detect difference between unread , deleted messages though. true of third party services. not detect read messages unless recipient turns on tracking images or clicks on tracking link.
