Storage lane
May 2026
The Storage lane is a cleanup bench.
It helps readers find the messages that weigh the account down: large attachments, old exports, duplicate sends, broken files, stale archives, and deleted mail that was never really gone.
Control model
What this storage lane has to hold.
Email needs a work surface, not a feed: inbox, send, accounts, newsletters, storage, and safety all serve different jobs.
File type, permissions
Archive, backup
Trash, spam, duplicates

Most asked
Storage questions, answered.
Short answers for the decisions people make before they post, watch, buy, clean up, reply, or lock something down.
Q.01
What should I delete first?
Large attachments, old promotional mail, duplicate files, outdated exports, and threads with files you already saved elsewhere.
Q.02
Why will attachments not open?
File type, app permissions, corrupted downloads, expired links, security scans, or mobile storage can all block opening.
Q.03
Does deleting mail free space immediately?
Not always. Empty Trash and Spam, then check provider storage after sync completes.
Q.04
Should I export mail?
Export before closing accounts, major cleanup, legal retention, job changes, or provider moves.
