ZLA Inbox

Replies, delivery & usage — on your phone

The mobile companion to the ZLA messaging portal. Answer the replies your customers sent, see where your last sends actually got to, and check exactly what you were billed — without opening a laptop.

Coming soon to the App Store Coming soon to Google Play

Already a ZLA customer? Use the web portal in the meantime — it does everything the app does, and more.

Three things, done properly

The app is deliberately small. It does what you need away from a desk, and leaves the rest to the portal.

Inbox

  • Every customer who replied, newest first, unread ones badged
  • The whole thread — what they sent and what you sent — in one place
  • Reply in your own words while WhatsApp's 24-hour window is open, with the time left shown on every conversation
  • Voice notes play inline, streamed on demand and never stored
  • Search by number or by message text

Recent messages

  • The last 100 messages you sent, newest first
  • The delivery status WhatsApp last reported: queued, sent, delivered, read or failed
  • The reason behind a failure, so you can act on it
  • Search by number, template name or status
  • Recipient numbers masked to their final four digits

Usage

  • This month, the last 30 days, last month or all time
  • Billed messages, Meta's cost, the markup and the billed total
  • A breakdown by message category and by recipient country
  • The full ledger of billed deliveries — every charge traces back to a message
  • Metered on delivery, not on send; free-form replies inside the window are not billed

A look at it

Every number and message shown here is invented — no customer's data appears in our screenshots.

Private by default

You are handling other people's conversations. We hold as little of them as the job allows.

Deleted after 3 days

Incoming customer messages are purged automatically. Not a setting — a rule.

Attachments never stored

Voice notes and files are fetched from WhatsApp at the moment you open them.

Session in the keychain

Held by the iOS keychain or the Android keystore, never in plain storage.

No tracking at all

No advertising SDK, no analytics, no crash reporter, no advertising identifier.

What you need

  • An existing ZLA workspace. Accounts are created in the web portal; the app signs in to one you already have.
  • An iPhone or an Android phone. Version 1.0 is a phone layout; a tablet layout comes later.
  • Nothing else. The app is free, has no in-app purchases and carries no ads.

Not a customer yet?

ZLA sends approved WhatsApp utility messages for businesses that need them to arrive — parts retailers sending warranty documents, clinics and labs sending a “your results are ready” notice — and gives you a place to answer the replies. Tell us what you send and we will tell you whether it fits.
