In your communications, there is a Feeds tab that allows you to send updated content as of the delivery date.
If you enable the option Update configured feeds contents right before communication send, the feeds will be updated at the time of sending, and the content will be created in the journey's library.
We recommend, however, not to configure too many feeds and to ensure that the "standard" update does not last more than a few minutes to avoid delays in scheduling the delivery.
If errors occur while updating the feeds during the delivery, we will not proceed with the sending. The system will attempt retries to overcome any temporary issues.
If you want to ensure that the delivery proceeds even in the case of issues with the feed update, activate the option Ignore any feed sync errors and send anyway with present content.
From the feed configuration page, you can click on Sync trials history to check the status of all attempts to synchronize the feed started by a communication.
