# Troubleshooting Campaigns and FAQs

When sending campaigns, you may face a scenario where you added your targeted lists and segment but your estimated recipients are 0 or there are sending or delivery failures. This article will address common issues and how to troubleshoot them.

## Estimated recipients showing 0 or less than expected

You may add your Send to lists and/or segments which has contacts but your estimated recipients are still showing 0 or less than expected.

### Why this may happen and what you can do?

**Missing valid identifier (email, phone or push token):** The contacts in your lists or segment do not have the valid identifier required for the channel selected for your campaign. For example,

* For Email campaigns, email address is missing for the contacts
* For SMS/WhatsApp/RCS campaigns, phone number is missing for the contacts
* For Push campaigns, push token is missing for the contacts

**Troubleshooting Steps:**

* Go to Contacts and apply advanced filters to match the criteria of your lists or segments
* Add condition if Properties of contact > Email address exists OR Phone number exists

<figure><img src="/files/L1RI27t9fHJv4XgDaSYi" alt=""><figcaption></figcaption></figure>

* You can click on any specific contact to see the identifiers like email, phone or push token

* If missing for some contacts, you can re-import them via csv or adjust your integration attributes mapping sync if the data is present in the source platform

**Subscription attribute not set as Subscribed:**  The contacts in your lists or segment do not have the Subscription attribute required for the channel set as Subscribed. For example,

* For Email campaigns, Email Subscription needs to be set as Subscribed
* For SMS campaigns, SMS Subscription needs to be set as Subscribed
* For WhatsApp campaigns, WhatsApp Subscription needs to be set as Subscribed

and so on.

**Troubleshooting Steps:**

* Go to Contacts and apply advanced filters to match the criteria of your lists or segments
* Add condition if Properties of contact > Email Subscription is Subscribed exists OR SMS Subscription is Subscribed OR WhatsApp Subscription is Subscribed etc. based on your channel for the campaign

* You can click on any specific contact to see the attributes like Email Subscription, SMS Subscription, WhatsApp Subscription and so on

<figure><img src="/files/rImZBW8AdF37ZNVuk6C1" alt=""><figcaption></figcaption></figure>

* If the relevant subscription attribute is missing for some contacts, you can update the attributes by re-import them via csv or adjust your integration attributes mapping sync if the data is present in the source platform.

**Contact identifier (email, phone) is suppressed:** The contacts in your lists or segment  are suppressed for the channel selected for your campaign for marketing use case. For example, contact's email address is suppressed for Email marketing.&#x20;

**Troubleshooting Steps:**

* Go to Contacts and apply advanced filters to match the criteria of your lists or segments
* Add condition if If contact can receive Email Marketing OR SMS Marketing etc. based on your channel for the campaign

<figure><img src="/files/5IkPMIshWphakPYp50o3" alt=""><figcaption></figcaption></figure>

* You can click on any specific contact to see if their is a suppressed status on their identifier

<figure><img src="/files/nnjxvLFtS3RmbcS2N9iI" alt=""><figcaption></figcaption></figure>

* You can also search for the email or phone number in the **Audience > Suppression lists** section
* If you want to unsuppress the contact, you can manually go to their 3 dots and unsupress them, however we do not recommend unsuppressing unless you are sure that they have wrongly been suppressed. Identifiers will get automatically suppress due to opt outs and invalid identifier

**Don't Send to option has reduced your final recipients:** The contacts in your included lists or segments under Send to have been reduced due to exclusion lists or segments you have selected under Don't Send to&#x20;

**Troubleshooting Steps:**

* Go to Contacts and apply advanced filters to match the criteria of your lists or segments
* Further add conditions which match the criteria of your exclusion lists or segments to check the final count of your contacts

**Missing contact locale when using Strict locale matching:** The contacts in your included lists or segments do not have the Locales attribute set with any value and you have selected Strict Locale matching.

**Troubleshooting Steps:**

* Go to Contacts and apply advanced filters to match the criteria of your lists or segments
* Add condition if Properties of contact > Locales has any value&#x20;

<figure><img src="/files/fB492eNnAuQ7YdPJLuuN" alt="" width="375"><figcaption></figcaption></figure>

* You can click on any specific contact to see the value of the Locales attribute
* If missing for some contacts, you can re-import them via csv or adjust your integration attributes mapping sync if the data is present in the source platform

## Campaign messages are not sent

Your campaign has Sent status but has sent 0 or less than expected as compared to the targeted recipients

* **Re-check your estimated and targeted recipients:** If you have missed this while building the campaign, check your estimated recipients by viewing your campaign again.

<figure><img src="/files/EutAKhcvLptJgkHvvcEK" alt=""><figcaption></figcaption></figure>

Note that your targeted segment is dynamic it may change over a period of time, hence you can check the **Recipients** metric in Campaign report which indicates what was the target audience at the time of sending

<figure><img src="/files/iY3dBIAumfGvgK7J4vlk" alt="" width="322"><figcaption></figcaption></figure>

* **Limit maximum recipients:** If you have set a max recipient limit when building the campaign, it will restrict sending to that number
* **Check Failure Reasons Tab in Campaign Reports:** Go to Campaign Reports > Failure Reasons to check why your messages are skipped or failed sending

Sending Failure Reasons will prevent all or partial messages of the campaign to be not sent. These can include the following:&#x20;

## Campaign messages are sent but not delivered

This means that Bird has sent the message but it has not been successfully delivered to the recipient. This may happen due to a variety of reasons.

**Campaign Reports:**

* **Failure Reasons Tab in Campaign Reports:** Go to Campaign Reports > Failure Reasons to check why your messages have failed delivery

<figure><img src="/files/oRDardEliKvuAxZKbMzA" alt=""><figcaption></figcaption></figure>

You can also check the following sections in Campaign Report

* Campaign Reports > **Recipient Activity > Bounced** for Emails
* Campaign Reports > **Recipient Activity > Failed** for SMS, WhatsApp and Push

Additionally, you can go to check the message logs for each platform

**Message Logs:** Go to Developer > Select the platform and got to Logs to check the error.

* Developer > Email > Emails Log
* Developer > SMS > Message Log
* Developer > WhatsApp > Message Log

For any WhatsApp related delivery error messages coming from Facebook, please refer to the details on [WhatsApp Error Documentation](https://developers.facebook.com/docs/whatsapp/cloud-api/support/error-codes/).

## Campaigns seems to be stuck as Ongoing

Certain campaigns may take longer period of time for sending especially when the scheduling is based on Recipient local timezone.

It may take 24-48 hours to run the campaign for all timezones of the world. However, you can easily monitor the campaign report in real-time and sometimes majority of all your messages may have already been sent while waiting for a few timezones to come.
