CHW-4217 InvalidEmail

email failed validation; use a business email address accepted by the org policy

Default message: email failed validation; use a business email address accepted by the org policy
HTTP status: 400 (client)

Problem. The email failed the org’s business-email validation. Cause. The org policy requires a business email (or explicitly opted in to non-business invites but the submitted address still failed another rule). Fix. Use a business-email address, or ask an owner to enable allow_nonbusiness_invites for the org. HTTP 400.
