HumanMail Agent: Uniquely Human Emails, For Every Buyer

Most AI email is written for the sender. HumanMail Agent writes for the buyer, in their style.

Free for 7 days. No credit card.

A cold email from Snowflake to a buyer at Walmart, written by Claude alone, next to the same email rewritten by HumanMail Agent. Claude’s email is polite and competent and uses the same signal, Walmart is hiring 40 new sales roles, but it reads the same for every buyer and opens with “I hope this email finds you well”. HumanMail Agent rewrites it for one buyer at a time. For Ryan, VP Sales, an I type, it is warm, short and a little witty, and opens with a public, work-context human touch: his recent podcast on ramping new reps. For Megan, VP Revenue Ops, a C type, it is data first with no fluff, and opens by agreeing with her post on forecast error. The signal is the same on both sides; what changes is the person reading it, with the DISC style from People Research Agent. HumanMail Agent also drafts replies when buyers write back, in the same DISC style..

A sample email, side by sideSample, fictional company

To: Megan ReyesVP Revenue Operations · DISC: Dominant first, Influential second
Signal: new forecast review process

A generic AI email

Hi Megan, I hope this email finds you well! I wanted to reach out and share some exciting updates about our platform that I think would be valuable for you and your team. We help revenue leaders like you unlock insights and drive growth. Would you be open to a quick call to explore how we might be able to help?

Written by HumanMail Agent

Subject: Your new forecast review

Megan, your team moved to weekly forecast reviews last month. Reps at teams like yours lose about 6 hours a week preparing for them.

We cut that to under one. 15 minutes, Thursday? I will bring the numbers.

Why it reads this way

  • Short and direct. Megan is Dominant first: she decides fast and skips small talk, so the email opens on her problem, not on us.
  • One number, one ask. Data first, then a specific time. No "explore" and no "hope this finds you well".
  • A real reason to write. It leads with a signal on her account, the new forecast reviews, so it is about her week, not our product.

If she replies

HumanMail Agent drafts the reply in the same style, and the follow-up if she goes quiet, with what changed on her account since.

FAQs

  • HumanMail Agent writes sales email for the buyer and replies to the emails buyers send back, using each person’s DISC personality and communication preferences from People Research Agent, account news from Account Research Agent and site visits from Visitor ID. The same message is rewritten for how each reader reads.

  • Claude or ChatGPT can find the same public news, like a hiring spree, and write a polished email from it. What they don’t know is how the person reading it thinks. HumanMail Agent adds each buyer’s DISC personality from our proprietary model in People Research Agent and a human touch from what they post, so an I type gets a warm, short note and a C type gets the numbers first.

  • Yes. HumanMail Agent reads the email a buyer sends back and drafts the reply in that buyer’s DISC style, using their profile from People Research Agent, the account context from Account Research Agent and the whole thread. It also writes the next follow-up by finding what changed since their last reply. You review every draft and send it yourself.

  • DISC is a personality framework with 4 styles: Dominance, Influence, Steadiness and Calculation. People Research Agent predicts a buyer’s style from public data, and HumanMail Agent uses it to set tone, length and detail.

  • HumanMail Agent V2 writes each email from scratch on the latest frontier models, with no fixed template. The buyer’s profile goes in first, then Account Intelligence, site visits, email history and market signals. HumanMail Agent now also reads a reply and writes the next email, and you set the tone and angle right in your compose window.

  • Write For Me is one button in your compose window. You pick the tone, add a line of context such as “cold outreach, they are hiring fast”, and HumanMail Agent writes the email from 5 sources: the buyer’s DISC profile from People Research Agent, account news from Account Research Agent, who visited your site from Visitor ID, your email history with the buyer and buyer intent, which comes with Buyer Signals. It shows why it wrote each line, and if a line is not right you type what to change and it rewrites in place.

  • HumanMail Agent works in Gmail, Outlook, Salesforce, HubSpot, Outreach and Salesloft, through the Chrome, Firefox and Outlook extensions, and in the Humantic AI app.

  • HumanMail Agent writes first touches, follow-ups and replies to buyer emails, plus social messages and call scripts, each tuned to the buyer. It is built for AEs and BDRs, on deals with one buyer or a whole committee.

  • HumanMail Agent works with the other 7 Humantic AI products on one Buyer Intelligence platform: Account Research Agent (Account Intelligence) researches the account; People Research Agent (People Intelligence) profiles each buyer; Visitor ID (Visitor Intelligence) identifies who is on your website; Intent Scoring (Intent Intelligence) shows which accounts are in market; Buyer Signals give account and people signals and keep an Account Research Agent report current on your schedule; Data Streams are live data pipelines for jobs, tech stack changes and website visitors; and Context Enrich adds unique buyer context to the AI you build. Humantic AI runs on 3 surfaces, the web app, the API and MCP, and Kairos, the activation engine, puts every product inside the tools your team already uses.
