Hi , I need to capture only one email with attachment from my gmail account through TA though we there is 2 same emails with attachment - please help on this.

You will either need to find a way to distinguish between the messages to only take one (this can be if you get multiple deliveries of an email because multiple aliases are processed, then you can set TA to only process the one that is delivered to the "main" alias)
Or you will need to create a database that lets you identify if you have processed the message before. A small database usually checking the subject and sending times, or alternatively looking at the originating message identifiers, and then you can query this database as part of your automation.
