Hi there,
These are great questions! In order to be able to share a read-only link to your Interface without giving base access, you are correct that you would need to be on a Pro or Enterprise plan.
On any plan, you can automate sending a link to your interface dashboard via an email digest automation. You could set up an email to run at regular intervals (daily, weekly, monthly) to send a link to your desired interface page. Run limits for each plan type can be found here. It is worth noting that on our Free Plan, Plus Plan, and Pro Trial offerings, we only allow users to email other Airtable collaborators (who are collaborators on the base you are sending the automation from) when using the native Send an email action. As a workaround, we recommend either adding the collaborator to the base or considering using the Gmail: Send email or Outlook: Send email actions which are not limited by collaborator restrictions on any plan level.
Hope this helps ☺️
