Tool to get my Gmail KPI's

Hey guys.

Wanted to pull some data from Gmail account for specific email subject line, just to see those analytics.

Eg. "Requesting invoice" - subject line.
Would like to see how many times in a month I recieve that particular email.

Is there a tool, software or method that anybody could recommend that would help to pull the data.

Thanx guys.
