wamail revoked <account> <stanzaId> removes the local copy of a message deleted for everyone
wamail send <account> [-- recipients...] sendmail: reads the RFC 822 message from stdin
wamail query <account> <text> neomutt query_command (contacts and groups)
wamail react <account> [emoji] reacts to the message on stdin (pipe-message)
wamail delete <account> deletes the message on stdin (asks: everyone / me)
wamail archive <account> archives/unarchives the chat of the message on stdin
Maildir: ~/Mail/whatsapp (account "default") or ~/Mail/whatsapp-<account>, one folder per chat.
Config: ~/.config/wa-cli/config.json -> "wamail": { maildir, backfillDays, backfillLimit, mediaMaxBytes, skipChats }
