Landbase now checks the email domain on a Do Not Contact entry against each company's website domain, so a company on the list is recognized in dialer and LinkedIn work when the two domains match. Users can also delete Do Not Contact entries one at a time or in bulk and add them back later, but contacts who opted out themselves cannot be removed.
Do Not Contact matching is more reliable across channels, though dialer and LinkedIn coverage still depends on website domains or enrichment being present, and opt outs made by the contact stay locked.
