Message and storage limits on the Free plan

Slack can be used for as long as you'd like on the Free plan, but here are some things to keep in mind:

  • Message visibility limit — Only the most recent 10,000 messages will be searchable and viewable.
  • File storage limit — Teams on the Free plan share a total of 5GB of file storage space.
  • Teams can add up to 10 third-party or custom integrations. 
  • Only Team Owners have the ability to upgrade their team's plan, which would remove the message visibility, integrations, and file storage limits.

Message visibility limit

Team members can send unlimited messages in Slack, but only the most recent 10,000 will be searchable and viewable.

If your team exceeds the message visibility limit, that’s alright! You’re building a valuable record of team knowledge, and you can continue sending messages. The oldest messages will be stored safely in your team’s archives, ready for you upon upgrading.

Team Owners can upgrade to a paid plan and make all of the messages in your team’s collective archive immediately available to search and view again. 

📝  How messages are counted

Slack counts anything typed into the message input box and sent as one message. 

Sending a one word message (even a single jumbomoji) is the same as sending a 975 word multi-paragraph message. Messages from bot users, URLs, snippets, posts, uploaded files, emoji reactions, file comments, messages in archived channels, and message thread replies count towards your team’s total number of messages sent.

File storage limit

Teams on Slack’s Free plan have a total of 5GB of file storage to share. If you’ve reached the limit, files will remain accessible in Slack but you won't be able to upload any more. You can delete shared files to make room for new ones or upgrade to a paid plan.

By upgrading, your team’s allotment of file storage increases collectively for every member of the team:

  • Standard plan — 10GB for every member
  • Plus plan — 20GB for every member

Here's an example:

Let’s say there are 50 members on your team and you’ve decided to upgrade to the Standard plan. That means your team will have 500GB of file storage to use together. Go ahead, upload your PDF docs, pictures, audio and video clips and more! ✨
