Social Media Scheduling for Authors in 2026 [Updated Guide]
BulkPublish is a social media scheduler for authors. Writers want to write, and a book launch asks for months of posting: the cover reveal, the pre-order reminder, the launch day, the reviews, the paperback. BulkPublish lets you plan the launch as one batch, puts the everyday posts on a slot that repeats, and turns each new newsletter or blog post into a social post from its feed. It publishes to Instagram, TikTok, Threads, Facebook and Pinterest.
Updated October 2026. The limits, post types and integrations below are read from the app itself every time this site is built.
The networks this audience uses most
These are the networks this page is about, with what BulkPublish can publish to each and the caption length it checks before a post is queued. Every one has a guide of its own.
| Network | What you can post | Caption limit |
|---|---|---|
| Feed Photo, Feed Video, Reel, Story, and Carousel | 2,200 characters | |
| TikTok | Video and Photo Slideshow | 2,200 characters |
| Threads | Text, Image, Video, and Carousel | 500 characters |
| Post, Reel, and Story | 63,206 characters | |
| Pin, Video Pin, and Carousel | 500 characters |
That is where this kind of work usually goes, but it is not the limit. BulkPublish publishes to 15 networks in total, and one post can go to every one you have connected in the same click. The rest are:
What this workflow needs
What a book launch, and the months either side of it, needs:
- RSS autoposting. Point BulkPublish at a feed and every new item becomes a post, on the networks you pick, in the wording you set up.
- Recurring schedules. Set a slot once, daily, weekly or monthly, and posts go out on it without anybody opening the app that morning.
- Media library. Images and video are uploaded once and reused, and every file is checked against each network’s size, format and length limits before the post is queued.
- Bulk publishing. Paste or upload a batch and the whole set is created at once, each post checked against its own network before it is queued.
Working with AI agents
For an author this means an assistant can take your launch plan and draft the whole run, so your writing time stays writing time.
BulkPublish runs a hosted MCP server, so an AI assistant can do this work with you instead of you copying its answer into another tab. It exposes 20 tools over OAuth: an agent can see your channels, draft a post, put it in the queue, publish it and read the numbers back afterwards. Nothing to install, no API key to paste.

Every assistant we support has a setup guide of its own.
Getting started
- Create an account. The free plan does not ask for a card.
- Connect the channels in the table above. Each one is a normal sign-in on that network’s own site, and you can disconnect it whenever you like.
- Set the slots you want to post on, or bring a batch in and give each post its own time.
- Look at the queue the next morning. Anything a network refused says so in that network’s own words, and can be sent again.
Common questions
Can I plan a whole launch in advance?
Yes. Create the batch in one sitting, from cover reveal to launch day, with each post’s time set.
Can my newsletter post itself?
Yes, if it publishes a feed. Each new issue becomes a post on the networks you choose.
Can I post book trailers and cover images?
Yes. Images and video are uploaded once, reused across posts, and checked against each network’s limits first.
Do I need to post every day?
No, but if you want to, a recurring schedule can post on a slot you set once while you get back to the manuscript.
Is there a free plan?
Yes, and it does not ask for a card. The pricing page lists what each plan connects and how much it posts.
Can an AI assistant post for me?
Yes. The hosted MCP server lets an assistant draft, schedule, publish and read your analytics over OAuth, with nothing to install and no key to paste.
