Reading and organising

Inbox, Drafts, Sent, Spam, Trash and Archive combine the matching folders of all your accounts, while each account's own folders stay available below.

Optionally group the messages of a thread into one row and read them as a stack of cards; the flat message list remains the default.

Manage server folders, pin favorites, color folders, label messages with tags and keep searches as smart folders.

Preview safe file types directly in FOLD and save everything else explicitly; on the Mac every saved file carries the quarantine flag.

What FOLD shows without a connection, how the outbox holds your mail, and how incomplete messages are flagged and reloaded.
