Controls how email addresses are matched. 'Only the domains listed' searches for exactly the suffixes you enter in the field below (the original behaviour). 'Any email address' accepts every address found in a profile description, whatever the domain. 'Business emails only' accepts any address except those from free webmail providers (Gmail, Yahoo, Outlook, Hotmail, iCloud, AOL, Proton and similar), which is the better choice for B2B outreach. The two broad modes find emails that a fixed domain list would miss, but expect fewer results per search and some noise, so combine them with 'Verify email domains' and consider adding Exclude words.
