Ruby on rails 4 - Why i am not able to see any emails using letter_opener gem?



i am using RoR 4 and trying to check my email remplate using letter_opener.But i cannot even find the tmp/letter_opener folder present as i think C9 is not allowing me to send any email outside of it.

If i cannot view my email templates. is there any other way to do that.?

Thanks in advance.
