What is the Email Writer Agent?
The Email Writer Agent is Cubeo AI’s tool for automating customized outreach that resonates with each lead’s profile. By gathering insights from LinkedIn, web sources, CRM data, and engagement history, the Email Writer Agent crafts emails and LinkedIn messages that make your communication feel relevant, authentic, and personalized.
Key Capabilities of the Email Writer Agent
- Automated Message Drafting: The agent generates tailored email and LinkedIn messages, drawing on key data points like job title, recent activity, and industry challenges.

How the Email Writer Agent Works
- Gather Lead Data: The agent begins by collecting relevant information from CRM data, engagement history, and online sources like LinkedIn and other publicly available information. If the LinkedIn profile isn’t provided, the agent searches for it based on the recipient’s name and email, building a more complete profile.
- Scrape Relevant Details: Once a LinkedIn profile is located, the agent gathers important details—such as job role, recent activity, and interests—providing deeper context for crafting the message.
- Compose a Personalized Message: Using the gathered data, the Email Writer Agent creates a message tailored to the lead’s background and business context, highlighting shared interests or relevant insights, and ending with a clear call to action.
- Sync and Review in HubSpot: Drafts are stored in HubSpot, making it easy for your team to review, adjust, and send personalized outreach directly from the CRM.
- Iterate Based on Feedback: The agent continuously improves message drafts based on feedback, fine-tuning communication to resonate better with specific audiences.

Use Cases for the Email Writer Agent
1. Scaling Personalized Outreach for High-Volume Campaigns
When handling large volumes of leads, maintaining personalization is challenging. The Email Writer Agent automates this process, creating unique messages that speak to each prospect’s specific role and industry. For example, if a campaign targets multiple industries, the agent can adapt messaging to highlight the distinct challenges and goals of each segment, ensuring that communication feels tailored to each recipient.
2. Timely Follow-Ups Triggered by Lead Engagement
Statistics show that timely follow-ups can increase conversion rates by up to 9x (InsideSales). The Email Writer Agent enables automated follow-ups triggered by engagement activity. For example, if a lead engages with recent marketing content, the agent can draft a follow-up message that references that content and suggests a next step—keeping the conversation timely and relevant.
3. Multi-Threaded Outreach for Key Accounts
For B2B accounts with multiple decision-makers, the Email Writer Agent crafts individual messages for each stakeholder, customized to their role and responsibilities. By engaging multiple contacts within an account, your team can build relationships across different departments, increasing the likelihood of buy-in and ultimately closing deals faster.
4. Re-Engaging Cold Leads with Targeted Messages
Re-engaging cold leads with personalized messaging can help rekindle interest and build rapport. The Email Writer Agent can create re-engagement messages that reference past conversations, shared interests, or recent industry news relevant to the lead’s business.
