The cronjob is throwing a warning message:
[PHP User Deprecation] Permission 'delete Mosaico templates' should be declared with 'label' and 'description' keys. See https://docs.civicrm.org/dev/en/latest/hooks/hook_civicrm_permission/ Caller: CRM_Core_Permission::assembleBasicPermissions at /usr/www/users/crmxxxxx/sub.domain.tld/vendor/civicrm/civicrm-core/CRM/Core/Error.php:1129
In a Drupal environment, this is sending an email every time the cronjob is running.
