Ad Audience Export (hashed emails)

Ad Audience Export (the Ad Audiences tab under Intelligence, on any paid plan) turns one of your contact lists into a file of SHA-256 hashed emails you can upload as a custom audience on Meta, Google, or LinkedIn Ads. The file contains only the hashes, never names, emails, or any personal data, so you can match your audience to an ad platform without sharing raw contact details.

Pick a contact list and choose Export hashed audience. Contacts that already have an email are hashed on the spot for free. Matching contacts that have no email is not available right now, so only contacts that already have an email are included in the export. The download is a single-column CSV of hashes, deduplicated. Exports are limited to 2,000 contacts per run, so split very large lists first.
