Social Media Scheduling for Ecommerce in 2026 [Updated Guide]

BulkPublish is a social media scheduler for online stores. A shop’s social feed is its shop window, and it is mostly the same photographs going to four different places at four different sizes. BulkPublish uploads each image once, checks it against what each network accepts, and queues the whole drop in one pass. Link clicks are measured on our own short links, so you can see which post did the work.

Updated August 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
Instagram Feed Photo, Feed Video, Reel, Story, and Carousel 2,200 characters
Pinterest Pin, Video Pin, and Carousel 500 characters
Facebook Post, Reel, and Story 63,206 characters
TikTok Video and Photo Slideshow 2,200 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 product feed asks of a scheduler, and where BulkPublish answers it:

  • 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.
  • Recurring schedules. Set a slot once, daily, weekly or monthly, and posts go out on it without anybody opening the app that morning.
  • 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.
  • Analytics in one place. Every published post is checked for its numbers, so all your networks sit in one dashboard instead of one browser tab each.

Working with AI agents

For a shop this means an assistant can take a product photo and a price, write a caption for each network and queue the drop while you are still choosing the date.

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 51 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.

Tools worth connecting

BulkPublish already talks to these, and each one has a setup guide.

Getting started

  1. Create an account. The free plan does not ask for a card.
  2. 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.
  3. Set the slots you want to post on, or bring a batch in and give each post its own time.
  4. 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

Do I have to resize images for each network?

No. A file is uploaded once and checked against each network’s size, format and length rules before the post is queued, so a file one of them would reject is caught first.

Can I schedule a whole product drop in one go?

Yes. A batch is created at once, and each post keeps its own network, caption and time.

Can I see which posts drove clicks?

Yes. Links in posts can go through our short links, which count clicks on every network, including the ones with no public metrics of their own.

Can it post automatically when I add a product?

Yes, if your shop publishes a feed. RSS autoposting turns each new item into a post on the networks you choose. Zapier can do it from a shop event instead.

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.

Still stuck? The Help Center walks through it step by step.

BulkPublish has a page for each of these too.
