I want to capture new email in inbox. I want something very tiny to accomplish this task. Arduino is quite big in size. Is anything available out there which I don't know by name. Please help.

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.
There are other options that you can try opting to in Arduino like their Nano, micro or Fio boards. They are quite more comfortable as their footprints are even provided in the link, you can actually design what kind of components you want in the board. Maybe you can try them, they are not as small as the lilypad but they can provide a better function as the fio board comes along with the wifi compatibility in the circuit. https://www.arduino.cc/en/Main/ArduinoBoardFio
You could use Arduino Lilypad, mainly used for wearable electronics because of its small size and for creating sewable electronic pieces.
Check out the existing projects done to get a good idea of its processing capabilities.
It has 9 I/O pins and an ATMEGA32u4 at its core.
I'm not quite sure of your requirements, so I'll just answer based on my understanding.
If you want a smaller version of an arduino then you can build an equivalent circuit on breadboard/protoboard. There's tons of examples out there so I'll jut link a few for you.
If you've already got an arduino lying around to program the chips then you can make the circuits pretty small and also teach yourself some useful skills in the process.
Less buying, more making I say.
Edit: After some clarification in the comments and it being email as opposed to physical mail you will either need an arduino with an Ethernet/Wireless shield. Or you can buy premade tiny Ethernet/Wireless controller as you will need network connection to use POP3 protocol
