Letterhead
Audience

Know and engage every reader.

Build lasting engagement and retention with every person in your audience list. Unified data across your operation, detailed per-newsletter reporting, powerful segmentation and targeting, marketing workflows and automations, and personalization to drive loyalty at scale.

Audience tools and data that drive one goal: deeper, lasting relationships.

Audience, in product

What the audience team actually works in.

Unified reader profile

One user-level record per reader. Every send, open, click, and preference in a single profile across all your newsletters.

MCP server

A per-tenant MCP server so an LLM can trigger sends, sync data, and act on changes with your permissions.

Segment builder

Build segments from dynamic, custom, and engagement-based fields. The ones your old ESP can't.

Audience tiers

Who reads what, where audiences overlap, how engagement breaks down. Surfaced as tiers you can act on.

House promos & cross-promotion

Cross-promote your other newsletters, paid tiers, and events without coordinating with editorial each send.

Journeys & automations

Welcome series, re-engagement, and beyond. Build flexible journeys with triggers and conditional branches.

Signup, subscriptions & preferences

Hosted signup and archive pages that match your brand, plus subscription and preference management readers control. Multi-newsletter signup built in.

Reporting & exports

In-app reporting on a cadence, plus exports to your warehouse when you need the raw data.

Automatic engagement tiers

Every subscriber lands in a behavioral tier, from loyalists to ghosts, each with a recommended next move.

Reader feedback inbox

Read replies in one place, track what needs attention, and clip the highlights worth sharing.

See your audience in a whole new light.
