How do I invite someone to my team?
Visit the Team page in your dashboard. From there you can invite new members and set their permission level.
Permission levels
Admin — Full control over the account. Admins can manage billing, download invoices, invite and remove users, manage integrations, access the API, consume credits, and view all contacts and features.
Member — Can consume credits, view all contacts, and access all features except integrations and API management.
Changing roles and removing members
Only admins can change the role of other team members. To modify a role, click the pen icon next to the member on the Team page.
To remove a member, click the trash can icon.
Keep in mind that granting admin permissions to someone gives them full control over the team, including the ability to remove other members.
How can I find out who added a particular contact?
Use the dashboard filters to see which team member added a specific contact.
Credit usage per user
You can see detailed credit usage broken down by team member, with filters by date and user — useful if you need more granularity than the general dashboard summary. See Credit History per User for more.
