Marketing use cases

First-touch Cold Email

Write a personalised, concise first email that opens a conversation without pitching — referencing a specific trigger or insight.

Multi-step Sequence

Build a 4–6 email cold sequence with varied angles, spacing, and a clear break-up email to maximise reply rates.

Subject Line Variants

Generate 15 subject line variants for a cold campaign — testing curiosity, directness, personalisation, and benefit-led approaches.

Persona-based Templates

Create distinct cold email templates for each ICP persona — different pain points, language, and angles.

Trigger-based Outreach

Write outreach emails based on specific triggers — funding announcements, job postings, product launches, or recent content.

Reply Rate Optimisation

Audit existing cold email copy for clarity, personalisation, length, and friction — then rewrite for maximum reply rate.
