**Your software**

- **My Mautic version is:** `5.2.5`
- **My PHP version is:** `8.1` (from `mautic/mautic:latest` Docker image)
- **My Database type and version is:** `MySQL 5.7` (running in a Docker container)

* * *

**Your problem**

**My problem is:**  
Campaign emails are not being sent even though everything appears to be configured correctly. Here’s the full situation:

- Contacts are correctly assigned to the segment via dynamic filter (`Email is not empty`)
- Segment shows the contacts in the UI and is verified in the database (`lead_lists_leads`)
- Campaign is active, published, and wired to the segment with a “Send Email” action
- Email is published, set as a **marketing email** , and sends successfully via the “Send Test Email” button
- Cron jobs are being executed manually using the following CLI commands inside the container:

makefile

CopyEdit

```auto
mautic:segments:update
mautic:campaigns:rebuild
mautic:campaigns:trigger
mautic:messages:send

```

- These run without error, but result in `Messages sent: 0`

* * *

**These errors are showing in the log:**  
Please advise  
No errors appear in the Mautic logs or output. Everything completes successfully, but messages are not queued or delivered.

* * *

**Steps I have tried to fix the problem:**

- Confirmed contacts are correctly listed in the segment using SQL:

sql

CopyEdit

```auto
SELECT * FROM lead_lists_leads WHERE leadlist_id = 1;

```

- Re-saved contacts and segment filter
- Cleared Mautic cache (`cache:clear`)
- Cloned the campaign and email to create a fresh flow
- Ensured email is not scheduled for future publish/unpublish dates
- Verified the `campaigns:rebuild` and `campaigns:trigger` CLI output shows correct execution of campaign events
- Confirmed segment contact count is `3` via SQL and UI
- Verified that test emails send successfully through Azure SMTP (ACS)

* * *

**Additional context:**

- Mautic is running inside Docker (`mautic/mautic:latest`)
- Emails are configured using Azure Communication Services SMTP
- CLI is being run from the Docker host using `docker exec`

If someone stumbles across this with the same issue, I found that I had created a segment email not a triggered one.
