Schedule and bulk publish X / Twitter posts

BulkPublish is a social media scheduler built for people who post to X / Twitter a lot. Connect your account once and you can plan a content calendar, auto-post on a repeating queue, and bulk upload a month of content in one go, whether you work from the app, a CSV, an RSS feed, the REST API or an AI agent. The same click can cross-post to every other network you have connected.

What you can publish to X / Twitter

BulkPublish supports 1 X / Twitter post type. It is checked before it is queued, so a post X / Twitter would reject never reaches your content calendar.

X / Twitter analytics

Every published post is checked for its numbers, so X / Twitter engagement sits next to every other channel in one dashboard instead of in X / Twitter’s own tab.

How to connect X / Twitter

  1. Create a BulkPublish account. The free plan connects three channels and does not ask for a card.
  2. Open Channels and choose X / Twitter.
  3. Sign in with X / Twitter and approve the permissions. BulkPublish stores the token, refreshes it on its own, and tells you if it ever needs reconnecting.
  4. Write a post, pick a time, and queue it. There is nothing else to install.

Ways teams use the X / Twitter integration

  • Bulk upload a month of X / Twitter posts from a CSV in one pass, then let the queue send them out at the times you set.
  • Write once and cross-post everywhere. The same post, adapted per network, goes to X / Twitter and every other connected channel together.
  • Turn a blog or podcast RSS feed into an automatic X / Twitter post the moment a new item appears.
  • Ask an AI agent to draft the week, review it in the content calendar, and approve it. The agent schedules to X / Twitter through the MCP server.

Frequently asked questions

Can I schedule X / Twitter 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 X / Twitter 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 X / Twitter the moment a new item appears. Both run on our servers, so they keep working while you are offline.

How many X / Twitter 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 X / Twitter content is one upload rather than thirty separate posts.

Can I plan a content calendar for X / Twitter?

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

What is the X / Twitter character limit?

280 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 X / Twitter account?

Yes. Connect as many X / Twitter 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 X / Twitter analytics?

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

Is there a free X / Twitter scheduler plan?

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