  3. Integration Hub: Slack boasts a vast marketplace of integrations with various apps and services, from project management tools like Asana to customer relationship management (CRM) software like Salesforce.
  4. Search Functionality: Slack’s powerful search feature helps you find past conversations, files, and information quickly.
