Frequently asked questions

Common questions about scheduling Bluesky posts with BulkPublish.

Can I schedule Bluesky posts in advance?

Yes. Pick any future time in your own timezone, or drop the post into a recurring queue slot and BulkPublish picks the next opening for you. Scheduled posts publish on their own, so nothing on your phone has to be awake.

Can I auto-post to Bluesky automatically?

Yes. A recurring queue publishes on a repeating weekly pattern without you choosing a date each time, and an RSS feed can auto-post to Bluesky the moment a new item appears. Both run on our servers, so they keep working while you are offline.

How many Bluesky posts can I schedule at once?

As many as your plan allows. Bulk Compose takes a CSV or a pasted list and turns it into a full schedule in one pass, so a month of Bluesky content is one upload rather than thirty separate posts.

Can I plan a content calendar for Bluesky?

Yes. The calendar shows every scheduled post across all your channels at once, so you can see what is going out on Bluesky next to everything else, drag a post to a new slot, and spot the gaps before they happen.

What is the Bluesky character limit?

300 characters per post. BulkPublish counts as you type and blocks anything over the limit before it is queued, so you find out while you are writing instead of when the post fails.

Can I post to more than one Bluesky account?

Yes. Connect as many Bluesky accounts as your plan allows, group them into channel sets, and publish to the whole set at once. Each account keeps its own schedule, its own analytics and its own token.

Do I get Bluesky analytics?

Published posts are checked for their numbers and shown next to every other channel, so you can compare Bluesky engagement against the rest without switching tabs. Link clicks are measured by BulkPublish itself, so they are available even where Bluesky reports nothing.

Is there a free Bluesky scheduler plan?

Yes. Three channels and thirty posts a month, with no card required. Bluesky counts as one channel per connected account.
