Slack Boost

Slack Boost notifies your team via Slack when posts publish, encouraging them to engage and amplify your content’s reach. Turn employees into advocates by making it easy to find and interact with your social content.

How Slack Boost works

You add Slack Boost to a post manually, or turn on auto-boost for a channel so every new post is boosted there
Once the post publishes to social platform(s), Ordinal sends a notification to your configured Slack channel
Your team sees the live post with direct links
Team members engage - likes, comments, shares - boosting visibility

The Slack message includes:

Post title (links to the post in Ordinal)
Button to view on each platform where it published
Your custom message, if you added one

Setting up Slack Boost

Connect Slack

Go to Integrations → Slack and click Marketing Boost Channels. Authorize Ordinal to access your Slack workspace.

Choose a channel

As part of the configuration, you’ll choose the specific channels you want to boost posts to e.g. #marketing-boost or #marketing.

Choose the default notification behavior

After you connect a channel, the channel settings modal opens. Notify channel of all posts by default is off — the channel is opt-in.

Leave it off to add Slack Boost manually on the posts you want to amplify.
Toggle it on and select Confirm to auto-boost every new post to this channel.

Select Cancel or dismiss the modal to keep the setting off. You can change this later from Integrations → Slack by opening the channel’s settings.

Slack Boost is configured. You can now boost posts to this channel.

Adding Slack Boost to posts

Manual boost

Open a post and scroll to Post Automations
Click + Slack Boost
Select the Slack channel
Add a custom message (optional)

When the post publishes, your configured channels receive the notification.

Auto-boost

Newly connected channels start with auto-boost off. To turn it on, open Integrations → Slack, select the channel, toggle Notify channel of all posts by default, and select Confirm. From then on, every new post automatically includes a Slack Boost to that channel — you can still remove the boost from individual posts.

Don’t over-notify. Reserve boosts for content where engagement genuinely matters - auto-boosting everything leads to notification fatigue.

Choosing the right channel

Target the right audience for each post. A company announcement might go to #all-hands while a product feature post goes to #product-team.

Channel example	Use case
`#social-boost`	All boost requests
`#marketing`	Marketing team content
`#leadership`	Executive posts
