Do you know who
your audience is?

You connect your ESP (like Kit). We sync your subscriber list and run each email address through our enrichment pipeline, which identifies the person behind it—their job title, company, industry, seniority, and company size—using public professional data. No surveys, no subscriber action required. It’s completely passive.

Yes, completely free with no limits. audience.is is built by BuySellAds, who runs the largest newsletter ad marketplace. When publishers understand their audience, they sell better ads—and we can match them with the right advertisers through BuySellAds. That’s how we make money. The enrichment tool is genuinely free.

Surveys typically get a 2–5% response rate, and the people who respond are self-selected—not representative. Enrichment works on your entire list, passively, and gives you real data instead of a small biased sample. That said, we include a survey tool too for things enrichment can’t tell you, like purchase intent or tool preferences.

Kit (ConvertKit) is fully supported today with automatic sync and incremental updates. Beehiiv is coming soon. If you use another platform, reach out—we’re adding integrations regularly.

No. Never. We don’t sell, license, or share individual subscriber data with anyone—not advertisers, not data brokers, not anyone. The enrichment data is only visible to you. You choose what aggregate numbers to share with sponsors.

We can still enrich many personal email addresses, though the success rate is lower than company domains. Your dashboard shows the breakdown so you know exactly what percentage of your list we could identify. Even a partial enrichment gives you data you didn’t have before.

The ESP sync takes a few minutes. Enrichment runs in the background after that—you’ll start seeing demographic data in your dashboard within minutes. A full list of 10–20K subscribers typically completes within a few hours.

That’s the whole point. Your dashboard gives you the exact numbers sponsors ask for—seniority breakdown, company sizes, industries, job titles. Use them in pitch decks, on sponsor calls, or in your media kit. We’re building an auto-generated media kit feature next.
