In short: Yes! Lately will automatically bulk-schedule multiple social media posts to publish out over daily, weekly or monthly intervals in seconds, no CSV file required.
To bulk schedule your posts, navigate to your Content Pipeline and choose the section that has your ready-to-publish posts. You can drag and drop to change the order of the posts if you would like, or you can just navigate to the righthand side of the page to the "Bulk Schedule" box. From there, you can select the frequency you would like your posts to be scheduled (you have lots of options!), choose the specific time of day or let Lately choose the optimal time based on your analytics and best practices! Once you do that, you can choose when you want your bulk scheduling to start and click "Set Schedule".
Voilà! You have bulk scheduled all of the posts in that bucket of your Content Pipeline!
