Usage limits for free workspaces

If you’re using a free workspace, there are specific usage limits to be aware of. Keep reading to learn more about message, file, data retention and app installation limits.  

Tip: Upgrading to a paid subscription will remove message, file and app limits, plus provide more data retention options.

Usage limits

  • Message and file visibility limit
    You can view and search messages and files from the last 90 days. Files include things such as clips, PDFs, documents, images, screenshots, and audio and video files. When your workspace reaches the visibility limit, Slack will start hiding messages and files older than 90 days to make room for new ones.
  • Data retention
    Workspace owners can use basic data retention settings: either keep all messages and files, or delete them after 90 days. If you choose to delete messages and files after 90 days, this will automatically delete any that become hidden by the message and file limit.
  • App installation limit
    You can add up to ten third-party or custom apps. If your workspace reaches the app and integration limit, you can uninstall apps to make space for new ones.

Note: The free version of Slack limits use for storage or spam. This kind of usage may prevent you from sending new messages. If you’re having trouble sending new messages or uploading files, contact our Support team.


Downgrading to a free workspace 

If you downgrade from a paid subscription to a free workspace (or cancel a trial), you’ll lose access to certain paid features. Here’s what to expect:

Messages, files and apps Usage limits will be reapplied to your workspace.
Slack Connect Slack Connect channels will disconnect. Each organisation will retain a copy of the channel.
Workflow Builder Any workflows created with Workflow Builder will remain active and count towards the ten-app limit. You will not be able to create new workflows, but you can remove existing ones.
Guest accounts Guest accounts will be deactivated (but you can reactivate guests as full members if you like).
Channel email addresses You can continue using existing channel email addresses, but you won’t be able to create any new ones.
