Your software
My Mautic version is: 5.2.1
My PHP version is: PHP/8.1.31
My Database type and version is: mysql:9.1.0

Your problem
I am trying to send a segment email following the Send Scheduled Broadcasts (Segment Emails) Cron Job documentation, but I am unable to do so.
My Cron Job executes, but it throws a Symfony\Component\Messenger\Exception\TransportException

My mautic cron file:

SHELL=/bin/bash
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
BASH_ENV=/tmp/cron.env

          • php /var/www/html/bin/console mautic:segments:update 2>&1 | tee /tmp/stdout
          • php /var/www/html/bin/console mautic:campaigns:update 2>&1 | tee /tmp/stdout
          • php /var/www/html/bin/console mautic:campaigns:trigger 2>&1 | tee /tmp/stdout
          • php /var/www/html/bin/console mautic:broadcasts:send --limit=200 2>&1 | tee /tmp/stdout

These errors are showing in the log:

If someone has the same issue, make sure to load the environment variables correctly inside the cron file (e.g., /tmp/cron.env) or directly in /opt/mautic/cron/mautic. In my case, the problem was caused by missing AMQP server environment properties.
