Overview

Writing effective sales outreach requires more than strong copy. It depends on product knowledge, audience understanding, brand voice, and the ability to adjust across channels such as email and LinkedIn. The Outreach Agent manages all of this automatically. Using the inputs you provide, along with research and built-in channel rules, it generates and sends tailored messages every day without manual writing.


What the Agent Uses to Write Outreach

The Agent draws from three main input sources to shape messaging and maintain consistency with your brand.

User Inputs in the Campaign Wizard

During setup, you define the core elements of the campaign:

  • Objectives – What the campaign should achieve (for example, booked demos or event registrations)

  • Materials – Source-of-truth information about your product and value proposition

  • Additional Instructions – Optional notes such as phrasing to avoid or competitors to reference

These inputs serve as the Agent’s foundation for messaging.

Post-Creation Controls

After launch, you can refine the campaign further:

  • Guidance – Plain-language instructions to adjust tone, emphasis, or positioning

  • Style Guide – Rules for brand voice, tone, formality, and structure

These tools allow you to steer outreach without rewriting messages manually.


How the Agent Applies Strategy

Before outreach begins, the Agent generates multiple Content Strategies—different approaches to framing your message based on persona, objectives, and Materials.

At first, prospects are assigned strategies at random. As results come in, the Agent evaluates which strategies produce stronger outcomes, such as replies or meetings. Over time, it assigns high-performing strategies to similar prospects.


What Happens Behind the Scenes

The Agent handles channel-specific details automatically.

Email

  • Applies subject line and deliverability best practices

  • Avoids flagged language and excessive links

  • Formats emails to read naturally, not like templates

LinkedIn

  • Short messaging designed for connect requests and direct messages

  • Tone adjusted for platform norms and relationship stage

No manual formatting or message rewriting is required. The Agent adapts content to each channel while keeping the message aligned with your inputs.


Personalized Messaging at Scale

The Agent personalizes outreach using validated prospect data.
Examples include:

  • Title – Adjusts tone and formality based on seniority

  • Company – References products or industry context when available

  • Location – Modifies phrasing or relevance for geography

  • Persona fit – Ensures messaging aligns with the campaign’s intent

Personalization is applied automatically during message generation and refined as the Agent learns from performance.


Summary

The Outreach Agent builds messaging from your objectives, Materials, and Style Guide. It generates multiple strategic approaches, tests them, and adapts messaging based on results. Each message is personalized to the prospect and formatted to the appropriate channel, allowing campaigns to run at scale without manual writing or formatting.
