Customer access

Customer access controls how unauthenticated email senders can create tickets.

Customer access settings showing restricted email ticket creation and allowed domains

Access typeBehavior
OpenAnyone can create tickets by email except senders from blocked domains.
RestrictedAuthenticated users and users from allowed domains can create tickets. Domains associated with existing customer organizations are also allowed.
ClosedOnly authenticated users can create tickets. Unauthenticated email-created tickets are rejected.

Restricted is the recommended default for most small teams.

Allowed domains are used in restricted mode. Enter bare domains such as example.com, not URLs like https://example.com.

Use allowed domains when customers from a company domain should be able to create tickets by email without being manually created first.

Blocked domains are used in open mode. Senders from blocked domains cannot create tickets by email.

Blocked domains help reduce unwanted tickets when open inbound email is necessary.

Domains added to customer organizations can also allow ticket creation in restricted mode.

This is useful for client, agency, or account-based support where an organization has multiple customers.
