Hi accounts17,

Custom domain per account/interview is now our top voted feature, and we’ve added it to our roadmap. We’ll definitely be building this soon! We don't have a date for it, but please vote for it in the Feedback forum and you’ll get a notification when it’s out. https://feedback.rumble.studio/feature-requests/p/custom-domain-in-invitation-link

When it's released, it will be immediately available on Tier 2 and Tier 3, for all existing & new customers (no add-on required).

Thanks,
Carl
