- Marketing Enterprise subscription: unlimited number of SSL-enabled domains.
Please note: standard SSL is available to all HubSpot Marketing Basic, Professional, and Enterprise customers free of charge. Alternatively, dedicated SSL or custom third-party certificates can be purchased. If you're interested in these options, please contact your Customer Success Manager.
