Store support

Email support@markbook.com with the order number, product, and a description of what happened. Never send a password, complete card number, setup token, or download token.

Support can help with delayed transactional email, expired setup or download links, billing access, pending Online seat deactivation, and order-state reconciliation.

• For billing changes, use the secure Billing Portal link after signing in.
• For team invitations, ask the current manager to resend or cancel a pending invitation.
• For Windows, include the displayed version and filename but not the private URL.

Product documentation and current MarkBook help are available from markbook.com/support.
