HubSpot CMS lets you add scripts that load on every page from a single setting.
- In HubSpot, go to Settings → Website → Pages.
- Choose the domain you want to update from the Select a domain to edit its settings dropdown.
- Open the Templates tab and find Site header HTML.
- Paste your Accessibird snippet and click Save.
Republish any pages that use cached templates so the new script is picked up.
