Magic Mail

Persona-tuned generative email copy

2023

Shipped an LLM email composer that tailors tone, sequencing, and data cues for every SDR persona.

Key achievements

  • Captured product intel, objections, and personas to personalize outbound email content.
  • Boosted positive reply rates by 80% across 40 pilot customers.

Project narrative

SDRs struggle to write personalized, prospect-aware emails at scale. Magic Mail automates this by generating tailored outreach and objection responses using fine-tuned LLMs.

I analyzed existing high-performing sales emails to identify effective structures, personalization patterns, and objection-handling strategies. These insights guided prompt engineering experiments and the curation of a fine-tuning dataset covering prospect details, industry context, and common objections.

The fine-tuned model generates both initial outreach and contextual replies. Magic Mail reduced email composition time by 250% and improved positive reply rates by 80% across pilot customers, freeing SDRs to focus on relationship-building.

Sequence Generator

Adaptive multi-touch outreach

2023

Created a generative engine that assembles personalized multi-channel outreach sequences in minutes instead of hours.

  • Cut sequence build time by 90% with persona-aware prompts and context ingestion.
  • Streamed each step to the UI as soon as it was ready so SDRs could review progressively.

AI Sales Agent

Agentic SDR automation blueprint

2024

Architected a multi-agent system that connects Outplay's lead research, sequencing, email, and scheduling modules into one autonomous SDR assistant.

  • Mapped end-to-end workflows so an AI agent can progress prospects from research to booked meetings.
  • Defined dual autopilot and co-pilot modes to balance automation with human approvals.
