Introduction
This guide will help you switch from Slack to Element, a secure messaging platform built on the Matrix protocol. Element offers end-to-end encryption, federation, and self-hosting options.
Why switch?
- Slack stores all messages indefinitely with full access
- Data stored on US servers under Salesforce ownership
- No end-to-end encryption available
- Expensive for larger teams
- Vendor lock-in concerns
Why Element?
- End-to-end encryption by default
- Self-hosting option for full control
- Open source and federated protocol
- No vendor lock-in (Matrix is a standard)
- Free for small teams, affordable scaling
- EU-based hosting available
Prerequisites
- Slack workspace admin access (for export)
- Element/Matrix server (self-hosted or matrix.org or EMS)
- About 45 minutes for setup
- Team coordination for migration
Info: You can use the free matrix.org server, or self-host for complete control. Element Matrix Services (EMS) offers managed hosting.
Step 1: Choose your Matrix server
Option A: matrix.org (Free, quickest setup)
- Great for testing and small teams
- Visit app.element.io to get started
- Create accounts on matrix.org server
- Note: You don’t control the server
Option B: Element Matrix Services (Managed hosting)
- Visit element.io/matrix-services
- Choose your plan based on team size
- Get a managed, hosted Matrix server
- Best balance of convenience and control
Option C: Self-host Matrix (Full control)
- Set up a server (VPS or on-premises)
- Install Synapse (Matrix homeserver)
- Configure domain and SSL
- More complex but maximum privacy
Tip: For most teams, EMS provides the best balance of privacy, convenience, and support.
Step 2: Create your workspace structure
In Element, channels are called “rooms”:
- Create a Space (equivalent to Slack workspace)
- Create rooms for each Slack channel you want to migrate
- Set room visibility (public or private)
- Configure room permissions
Example structure:
- Space: “Company Name”
- #general
- #engineering
- #marketing
- #random
Step 3: Invite team members
Create accounts
- Team members create Element accounts
- Or use SSO/SAML if configured (Enterprise feature)
- Share the Space invite link
- Or invite individually to each room
For managed hosting (EMS)
- Use the admin panel to invite users
- Send email invitations
- Set up SSO for seamless login
Step 4: Export Slack message history (optional)
Slack history export depends on your plan:
- Free Slack: Only admins can export, limited history
- Paid Slack: Full export available
To export:
- Go to Slack Administration
- Navigate to Settings & Administration > Workspace Settings
- Click “Import/Export Data”
- Select “Export” and choose date range
- Download the export file
Warning: Free Slack plans only retain 90 days of messages. Export quickly if this matters.
Step 5: Set up bridges (optional)
Element can bridge to Slack during transition:
- Use the Slack bridge to connect rooms
- Messages flow between both platforms
- Gradual migration without disruption
For self-hosted: Set up mautrix-slack or other bridges For EMS: Bridge features may be included
Step 6: Train your team
Key differences from Slack:
- Threads: Use “Reply in thread” similar to Slack
- Reactions: Emoji reactions work the same
- Mentions: Use @username to notify people
- Encryption: Verify devices for secure messaging
- Search: Search works within encrypted rooms
Tip: Create a #help room for questions during transition.
Tips & Gotchas
Warning: End-to-end encryption means message history isn’t searchable server-side. Plan accordingly for compliance needs.
- Device verification: Encourage team to verify devices for security
- Key backup: Set up key backup to prevent losing message access
- Integrations: Many integrations exist but differ from Slack
- File storage: Files are stored on your Matrix server
- Mobile apps: Element has iOS and Android apps
- Desktop app: Available for Windows, Mac, and Linux
What’s Next?
