Anyone know how to get universal blocklist?

Hi harrison, thanks for reaching out. Taking a look at this. Can you add some context on what you mean by universal blocklist here? Is there a database you'd like to reference here?

like be able to reference a column or list in any list

Yes! If your blocklist is in an Excel sheet, you can import it directly into a Clay table. From there, you can use the lookup single row enrichment column to search for records within the table. Here’s a video that walks you through the integration: Loom Video.

We haven't heard back from you in a bit, so we're going to go ahead and close things out here - feel free to let us know if you still need something!
