Mail box crashing

Attached more than 25mb of photos in a new email from gmail account in iphone 5s mail and the mail box crashed. Now when mail is opened, it opens a blank screen and crashes in couple of seconds. When new emails come the counts do increase in the icon but can't view any. When opened it crashes in couple of seconds.Can't see this email in browser version since gmail doesn't allow to save this as a draft.

Reset my gmail account and added again. Didn't help. Switched off the phone and tried again. Didn't help. Somebody please help.

Thanks,
