ZLA Inbox

ZLA Inbox puts your business's WhatsApp conversations, delivery history and billing in your pocket.

It is the mobile companion to the ZLA messaging portal. Sign in with the same email and password you already use on the web, and you get the three things you need when you are away from a desk: the replies your customers sent, where your last sends got to, and what they cost.

INBOX
• Every customer who replied to one of your messages, newest first
• Open a conversation and read the whole thread, inbound and outbound together
• Reply in your own words while WhatsApp's 24-hour customer service window is open, with the time remaining shown on every conversation
• Play voice notes inline — the recording is streamed from WhatsApp when you press play, and is never stored on our side
• Search by number or message text
• Unread conversations are badged, and opening one marks it read

RECENT MESSAGES
• The last 100 messages you sent, newest first
• The delivery status WhatsApp last reported: queued, sent, delivered, read or failed
• Search by number, template name or status
• Recipient numbers are masked to their final four digits

USAGE
• Pick a period: this month, last 30 days, last month, or all time
• Billed message count, Meta cost, your markup and the billed total
• A breakdown by message category and by recipient country
• The full ledger of billed deliveries, so every charge traces back to a message
• Metered on delivered webhooks, not on send acceptance — and free-form replies inside the 24-hour window are never billed

PRIVACY BY DEFAULT
• Conversations are deleted automatically 3 days after they arrive
• Inbound attachments are never stored — they are fetched from WhatsApp on demand
• Your session is held in the device keychain (iOS)
• No advertising, no analytics SDKs, no tracking

WHO IT IS FOR
Businesses already sending WhatsApp utility notifications through ZLA — parts retailers sending warranty documents, clinics and labs sending "results are ready" notices, and any business that needs to answer the replies those messages generate.

WHAT YOU NEED
An existing ZLA workspace. Accounts are created in the web portal; this app signs in to an account you already have.
