Batch deployment
Contentful has a feature that allows a user to select any/all entries related to a given entry and deploy everything at once instead of having to go into each individual related entry and deploy them one at a time.
In Contentful there is a "References" tab at the top left of an entry's edit page.
This will display a list of all sub-entries and allow you to see all of their publish statuses and publish them all at once using the "Publish all" button (if necessary).
This can also help prevent missing publishing inner entries when publishing the "main" entry, which will help both the content creator and QA when they come to test it, as sometimes a buried child entry can be missed during the deployment process.
Note that some entries may be linked to too many other entries for Contentful to display them, so you may get one of the following errors, meaning that this won’t work in 100% of cases:
