What you get
Slack upgrades one workspace to the paid Pro plan at no charge when it has 250 members or fewer; larger workspaces and the Business+ plan get 85% off instead. Charitable-status checks go through TechSoup and usually clear in about three days. The benefit applies per workspace, so each workspace your org runs needs its own application.
How to redeem
- Set up a free Slack workspace for your organization if you don't have one.
- Submit the Slack for Nonprofits application with your workspace URL and charity details.
- Wait about three days for TechSoup validation.
- Accept the upgrade: free Pro at 250 members or fewer, or 85% off Pro and Business+ above that.

Worth knowing
Validation via IRS, local charity commission, or local TechSoup Global partner (multi-path — enum holds only primary path). Discount is per workspace; each workspace needs its own application. 'Organizations attempting to influence public opinion' is an exclusion broader than lobbying. Religious orgs excluded when promoting affiliation/dogma as core mission or in exchange for services.
