Assign Roles
Set Incident Response and On-Call roles during invitation.
Use Default Roles
Allow Rootly to apply your team’s default roles when no role is selected.
Streamline Onboarding
Send users directly into the account creation or sign-in flow.
Role Assignment
You can assign roles during invitation to control what access a user receives after joining.- Incident Response roles control access to incidents, workflows, retrospectives, and related configuration
- On-Call roles control access to schedules, escalation policies, alerting, and responder workflows
Configure default roles in Organization Settings to standardize access for new users.
Ensure you have available seats for the roles you’re assigning. If seats are limited, some roles may be unavailable.
Email Requirements
Invitations require valid email addresses that meet your organization’s requirements.- Valid format
- Not already a member
- Allowed email domain, if your organization restricts invitations by domain
Rootly validates email addresses during invitation creation. Invalid addresses will return an error.
User Acceptance and Sign-Up
After an invitation is sent, the user receives an email with a link to join your organization. When they open the invitation, they can complete sign-up using one of the methods available in your environment, such as:- Slack
- SSO
- Email and password

- At least 10 characters
- One lowercase letter
- One uppercase letter
- One number
- One special character
Bulk Invitations
When you invite multiple users at once, Rootly processes invitations in batches.- Invitations may take longer to appear for larger batches
- Individual errors do not prevent valid invitations from being created
- You can review progress from the Invitations page
Large invitation batches may take a few minutes to complete.
Who Can Send Invitations?
Invitation access depends on the user’s assigned permissions.- Owners can send invitations
- Admins can send invitations
- On-Call Admins may be able to assign On-Call access, depending on configuration
Contact your team administrator if you do not have permission to invite users.
Best Practices
- Configure default roles before inviting users with standard access needs
- Double-check email addresses before sending invitations
- Assign roles during invitation to reduce manual updates later
- Use bulk invitations when onboarding multiple users at once
- Review pending invitations and resend or remove them as needed
