Using Vendelux filters will cut down on your credit-usage, but more importantly, will save you time manually scrubbing the list for your target audience.
On the event details page, you can filter out attendees. I like to start by filtering only confirmed attendees, removing the sponsors, and then layering on a prospect list (you can also see which if the attendee belongs to any other prospect lists on the right).
From here you can layer in job titles with the filter (or use the ICP prospect list we just worked on). You can also cherry-pick exactly which attendees you want to enrich with contact details.
Once you've narrowed everything down, just click on Export Attendees > Export CSV with emails. This will send the enrichments directly to your inbox within 24 hours, or sooner (depending on the size of the export).
