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. Contacts without an email use a privacy-preserving identity match to get a ready-hashed identifier, which costs 3 credits per matched contact; contacts we can't match cost nothing. You confirm before it runs, and the cost is settled to the number actually matched. The download is a single-column CSV of hashes, deduplicated. If you run low on credits mid-way, the export still gives you all the free known-email hashes and tells you the rest weren't matched. Exports are limited to 2,000 contacts per run, so split very large lists first.
