MailSifu
mǎ · the way of the code

Codes,
mastered.

MailSifu is the quiet master at the gate of your inbox — sifting one-time codes from every verification email the moment they arrive. Your loyal mini-wolf fetches them, paws them onto your desk, and wags before you can blink.

From arrival to your clipboard,
in a single breath.

0 ms

Code lands in your alias inbox. Sifu opens one eye.

40 ms

Headers, body, attachments — all sieved through the OTP parser.

180 ms

Mini-wolf trots to your screen, scroll in mouth. Your move.

“Codes do not move faster than the master who waits for them.
They land where they belong — quietly, exactly,
and never twice.”

━━━━ Sifu, on the inbox · 信师语录 ━━━━

When your code arrives,
so will the wolf.
