**If your WhatsApp bulk campaign is not being sent in Papo's Disparador (https://papo.global/), the most common causes are: a Message Template (HSM) not approved by Meta, an empty or invalid contact list, a disconnected inbox, or inadequate sending settings. Most of these issues can be resolved directly in the Papo dashboard by reviewing the preparation steps and the broadcast parameters.**

Understanding why a broadcast fails is the first step to fixing it and ensuring your future campaigns are delivered successfully. The Papo platform centralizes the entire process — from audience creation to report analysis — and offers the tools to quickly identify and resolve bottlenecks.

| Common error | Probable cause | How to fix |
| :--- | :--- | :--- |
| Campaign does not start or remains in draft | Message template (HSM) not approved or expired | Check the template status in Meta Business Manager and wait for approval or recreate it. |
| No contact received the message | Empty contact list or incorrect segmentation | Access Papo's CRM and check whether contacts have the labels used in the campaign. |
| Messages not delivered (batch failure) | WhatsApp inbox disconnected or number blocked | Test the inbox connection in the Settings module and review usage policies. |
| Very low delivery rate | Invalid numbers, no WhatsApp, or no opt-in | Clean the list by validating country/area codes and removing contacts who did not consent. |

## 1. Message Template (HSM) not approved or missing
To start conversations outside the 24-hour window, WhatsApp requires a Message Template (HSM) approved by Meta. If the template is pending, rejected, or not selected in Disparador, the campaign will not be sent.

- **Check approval:** Go to Meta Business Manager and confirm that the template has the status “Approved.” Rejected templates usually violate content or category policies (Marketing, Utility, Authentication) — adjust the text and resubmit for approval.
- **Correct template and variables:** In Disparador, only approved templates appear in the list. If there are variables (e.g., `{{1}}` for the name), fill them in correctly. A formatting error can block sending.
- **Account sync:** The template must be associated with the same WhatsApp Business Account (WABA) connected to Papo. If it was created in another account, it will not be visible.

## 2. Empty contact list or incorrect segmentation
Disparador uses exclusively the contacts registered in Papo's CRM. If the database is empty or segmentation by labels (`tags`) returns no results, no message will be sent.

- **Check the CRM:** In the Contacts module, verify that there are records with correct numbers (including country code, such as +55 for Brazil, and area code). Contacts without a valid phone number are not included in the campaign.
- **Applied labels:** Make sure contacts have the label used in the Disparador configuration. For example, if you segmented by “active customers,” only contacts with that tag will be considered.
- **Populate the CRM:** If the database is empty, use tools such as Extrator (to capture leads from CNPJ or Google Maps) or import lists with consent.

## 3. Disconnected inbox or blocked number
The campaign is sent from a WhatsApp inbox (connected via the official API). If that inbox is disconnected or the number has been blocked by WhatsApp, messages will fail.

- **Test the connection:** In Settings > Inboxes, locate the inbox used in Disparador. If there is a disconnection alert, reconnect it or follow the steps to fix the channel.
- **Blocked number:** Sends with a high rate of spam reports, use of purchased lists, or excessive speed can lead to the number being blocked by Meta. If no individual message is going out, your number may be restricted. Reduce sending speed (e.g., 15 messages per minute) and review opt-in practices.

## 4. Inadequate sending settings
Parameters such as “Messages per Minute” and “Wait between Messages” directly influence delivery. Very high values can trigger API limits; zero or inconsistent values can prevent the campaign from starting.

- **Safe speed:** The recommendation is to use 15 messages per minute and a 180-second pause between batches. Adjust these fields according to your list volume.
- **Batch consistency:** The “Quantity per Time” field must be compatible with the total number of contacts. For example, send to 10 contacts every 180-second cycle.
- **Responsibility checkboxes:** Before starting, you must check the confirmations that you have the recipients' consent and that you are not using purchased lists. Without this step, Disparador keeps the campaign as a draft.

## 5. Lack of consent (opt-in) and purchased lists
Sending bulk messages to people who did not authorize contact is the main cause of blocks and delivery failures. Papo requires you to confirm opt-in before each broadcast. Purchased or scraped lists from the internet often contain invalid or outdated numbers, increasing the failure rate and the risk of reports.

- **Solution:** Work only with contacts who have interacted with your company or who voluntarily provided their number (explicit opt-in). Use the CRM to maintain a clean database with a consent history.

## How to diagnose failures using reports
After each campaign, Disparador displays metrics such as “Sent,” “Delivered,” “Read,” and “Failures.” Analyze the Failures column to identify which contacts did not receive the message and why (e.g., number without WhatsApp, invalid format). Based on this data, you can clean the list and segment only valid contacts in a new broadcast.

### Why does my campaign appear as “Draft” and not send?
Disparador creates campaigns initially as drafts. For sending to happen, you need to fill in all required fields (inbox, speed, audience, message template) and check the responsibility confirmation boxes. If any of these items is missing or if the user does not have permission to start broadcasts (access linked to plans such as Plano Ouro), the campaign will remain as a draft.

### What should I do when the message template does not appear in the list?
Only templates approved by Meta and associated with the same WABA account appear in Disparador. Check in Business Manager whether the template is approved. If it is, there may be a synchronization delay — refresh the page or wait a few minutes. If the template was created in another account, it will not be displayed; you will need to recreate it in the correct account.

### How do I know if my WhatsApp number has been blocked?
If all campaign messages fail and you cannot send even a simple text message through the Conversations module, your number may be restricted. Go to Settings > Inboxes and see if there is a blocking alert. In that case, contact Meta support and review your sending practices (speed, opt-in) before trying again.

### Can I resend a campaign that failed?
Yes. After fixing the cause of the failure (e.g., adjusting the template, cleaning the list, or reconnecting the inbox), create a new campaign in Disparador with the same segmentation. You can duplicate the previous draft, make the corrections, and start sending. There is no automatic “resend” button; you need to configure a new broadcast.

### How can I ensure my contacts are in the correct format?
In Papo's CRM, all numbers must include the country code (e.g., +55) and the area code. Use the Contacts module to review and edit records. Papo's Extrator, which finds leads in CNPJ and Google Maps, already delivers numbers in the appropriate format, reducing manual errors.

### What should I do if the campaign was sent but no one read it?
A very low read rate may indicate that the message is not attractive or that the sending time was not suitable. Review the template text, test different calls to action, and use variables to personalize (e.g., customer name). Campaign reports show the read rate; compare with other broadcasts to identify patterns.
