The safety net you never notice until you need it
Auto-save runs quietly enough that most people forget it exists -- until a browser crashes or a phone dies mid-email and a half-written message reappears untouched in the drafts folder the next time they open the app. It's a background process working the entire time, not a manual step you have to remember to take.
Drafts also work as a holding area, not just a safety net
Beyond recovering from accidents, the drafts folder is a useful place to intentionally park a message you're not ready to send -- one you want to reread with fresh eyes, or one you're waiting on more information before finishing -- rather than sending something half-formed just to get it out of the way.
Frequently Asked Questions
Do drafts count toward my storage limit like sent or received email?
Yes -- a draft is a real message stored in your account, including any attachments, so a folder full of large, unfinished drafts can still use up meaningful storage space.
Can I lose a draft if I close the app without saving?
Generally no -- auto-save typically runs every few seconds while composing, so closing the app usually preserves the most recent version rather than requiring a manual save first.
