Sending
Campaigns
A campaign sends one template to one audience. This page covers building it, what happens after you press send, and how to read the result.
Building one
| Choice | Notes |
|---|---|
| Sender | Which of your numbers it goes from. Defaults to your default sender. |
| Template | Only approved templates appear. |
| Audience | Everyone in it who has a reachable number. |
| Variables | Map each slot to a contact field or a fixed value. |
| Header media | Required if the template has an image, video, or document header. |
| Schedule | Send now, or pick a time. |
Before sending, the campaign shows how many people it will reach and what it costs — credits, or nothing if your plan includes sending. Check it. This is the last point at which nothing has happened.
What happens when you send
Sending does not contact Meta straight away. In one step Sendrix counts the recipients, reserves the credits, works out each person's variables, and queues a message per contact. A worker then sends them steadily in the background.
States
| State | Meaning |
|---|---|
| DRAFT | Being built. Nothing reserved, nothing sent. |
| SCHEDULED | Waiting for its time. Credits already reserved. |
| RUNNING | Going out now. |
| PAUSED | Stopped partway. Resume or cancel. |
| COMPLETED | Every message has a final result. |
| CANCELLED | Stopped for good. Unsent messages refunded. |
| FAILED | Could not run at all, for example the sender was removed. |
Watching it
The campaign page updates live: queued, sent, delivered, read, failed. Delivery and read counts arrive by webhook and can lag a few seconds behind the send.
| Count | Meaning |
|---|---|
| Sent | Meta accepted it. |
| Delivered | It reached the person's phone. |
| Read | They opened it. Only if they have read receipts on. |
| Failed | It will not arrive. The reason is shown per message. |
Pausing, cancelling, retrying
| Action | Effect |
|---|---|
| Pause | Stops sending. Messages already gone stay gone. Resume when ready. |
| Cancel | Stops for good and refunds everything unsent. |
| Retry failed | Queues another attempt for failures worth retrying. Only the ones already refunded are charged again. |
When sends fail
Some fail, most do not
Normal. Usually the number is not on WhatsApp, or the person blocked your business. Each message carries its own reason.
Everything fails
Something is wrong with the sender or the template, not the list. Check the sender on Senders, and that the template is still approved.
It slowed right down
Meta rate limits new numbers and raises the limit as you send reliably. Sendrix backs off when told to rather than hammering through, so a large campaign from a new number takes longer. This is expected and needs nothing from you.
Reports
Finished campaigns export as Excel or CSV, one row per recipient with their status, timestamps, and any error. Useful for handing results back to a client.
