Does "Mail" app on iPhone 5S iOS7 really takes 1,3G of memory space?

[iMore Question]

My inboxes, trashbins, sent messages ans draft folders are empty but according to storage infos in "Settings", the app still use 1,3 G of space. I've tried turning off and on my device, still, no changes.....

Where are you looking?

If you keep lots of messages, especially those with attachments it can be that big.
