How the Agent Writes Personalized Outreach

CallSine’s Agent generates intelligent outreach by combining your inputs with real-time data and best practices—no copywriting required.

Updated over 2 months ago

Overview

Writing effective sales outreach requires more than just strong copy. It takes a deep understanding of your product, your target audience, your brand voice, and your campaign goals—plus the ability to adapt across platforms like email and LinkedIn.

CallSine’s Agent handles all of this automatically. Using your instructions, AI-powered research, and built-in platform expertise, it writes and sends tailored messages every day—without requiring manual intervention.


What the Agent Uses to Write Outreach

The Agent pulls from three primary input categories to generate messages that match your goals and brand.

1. User Inputs (via Campaign Wizard)

When creating your Agent, you provide:

  • Objectives – What kind of success the campaign should drive (e.g. demos, webinar signups)

  • Materials – The documentation that defines your product, positioning, and voice (e.g. case studies, web pages, internal decks)

  • Additional Information – Optional instructions like “Avoid this phrase” or “Mention this competitor”

2. Post-Creation Controls

After your Agent is live, you can further steer messaging through:

  • Guidance – Plain-language instructions to adjust tone, targeting, or copy preferences

  • Style Guide – Defines how your outreach should sound (tone, formality, length, and structure)


How the Agent Applies Strategy

Before any outreach is written, the Agent creates multiple Content Strategies—distinct approaches to messaging based on your Materials, objectives, and persona.

Each Content Strategy represents a different way to frame your offer. These are tested in parallel:

  • At first, prospects are randomly assigned strategies

  • Over time, the Agent optimizes based on what’s working (e.g. which strategies drive replies, meetings, or signups)

What Happens Behind the Scenes

The Agent handles all the nuances of outbound communication for each channel:

  • Email

    • Applies best practices for subject lines, deliverability, and formatting

    • Avoids flagged keywords or excessive links

    • Automatically adjusts tone based on title and seniority

  • LinkedIn

    • Shorter message formats

    • Appropriate tone for connect requests, DMs, and comment replies

Note: You don’t need to manage formatting, tone, or length for each channel—the Agent adapts your inputs automatically based on platform best practices.


Personalized Messaging at Scale

To personalize outreach, the Agent uses prospect-level data like:

  • Title – Adjusts tone for seniority (e.g. C-suite vs. mid-level)

  • Company – References products, value props, or recent news

  • Location – Adjusts language or references for regional relevance

  • Persona fit – Filters messaging based on whether the prospect aligns with the campaign’s intent
