View reader interests on subscriber profiles

Letterhead automatically infers what topics each reader cares about from their engagement with your content, and shows those interests on the subscriber’s profile — an at-a-glance view of what matters to each person.

How it works

Letterhead infers each reader’s interests from what they engage with, so the interests you see reflect actual behavior rather than self-reported preferences.

Viewing reader interests

Open any subscriber’s profile from the Audience section and look for the interests section, alongside their activity log and engagement summary.

Segmenting by interests

Build targeted segments with interest-based criteria, then use them for targeted sends — relevant content based on demonstrated interest rather than assumptions.

For the rest of the Audience toolkit, see Working in Audience.
