Never forget to send a previously drafted email again. GDrafts displays the current number of draft emails for each GMail account on a device. Accounts are represented by unique notifications and can be enabled / disabled independently. Each notification provides quick actions to compose a new email, jump to drafts list, and adjust GDraft settings.
NOTE: This is an ad supported version of GDrafts. Ads will be displayed on the settings screen and when clicking through notification actions. An ad free version of GDrafts can be obtained here: https://play.google.com/store/apps/details?id=com.tkj.gdrafts.paid
