How to personalize cold emails with account and contact research
Twain uses your campaign brief, CRM context, and live web evidence to qualify each prospect, then writes the email from that research.

Public evidence Twain publicly documents bidirectional Salesforce and HubSpot sync
Used in the email Whether Twain needs a third CRM integration
What Twain uses before it writes the email
Twain does not treat a first name and company as enough context. It checks four inputs before it decides whether to write and which evidence belongs in the email.
- 01Company knowledgeYour ICP, offer, proof, and language Twain should use.
- 02Campaign briefWho you want to reach, why now, and what the email must do.
- 03CRM contextAccount history, ownership, and facts your team already knows.
- 04Live web researchCurrent evidence that changes the qualification, angle, or wording.
One email with the sources and decisions behind it
Twain shows the sources, what it could not verify, and why it chose that message angle.
A hypothetical campaign, researched in Ultra
Why Twain wrote this email
We ran a hypothetical Merge Unified campaign with Mohamed Chahin as the prospect. Ultra checked the public evidence, built the Thesis and Strategy, and wrote the draft below.
Ask what happens after Salesforce and HubSpot without assuming demand
Ultra did not assume that Twain needs a third CRM integration. It framed a third integration as a technical-fit question and left out claims about buying intent, partnership, ROI, headcount, pricing, and customer metrics.

Mohamed Chahin Founder & CEO · Twain Ultra Campaign Hypothetical Merge Unified campaign Subject
Twain API integration
Hi Mohamed,
Twain's docs now show bi-directional sync for Salesforce and HubSpot, and from what's public those are the two CRMs on your surface. Your customers run revenue teams on plenty of others, so I'd guess the connector-three question comes up soon, if it hasn't already.
Merge is one CRM integration that reads and writes across the category, and we maintain the underlying connectors. The two you built stay as they are. This would cover whatever your customers ask for next.
The open question is whether normalized models hold up for your research-and-write workflows, and that's what a call would settle.
Would you be open to a 20-minute technical fit check?
The subject and body are shown exactly as Ultra generated them, with no manual edits.
Merge did not send this message, and the example does not imply a relationship, evaluation, or partnership between Merge and Twain.

What customers report after using Twain for cold outreach
- Reply rate
12% positive
Replies on cold outbound
Before Twain our outbound outreach was very generic and did not tackle individual pain points. Now we send 1:1 deep researched emails and we see 12% positive reply rates, whilst we send highly specific messages on scale.
In my 12 years of doing outbound, I have never seen this.
- Message quality
Sounds human
Not a template, speaks to real pain point
Most AI outreach tools just make it faster to send worse emails.
Twain's contextual research actually digs into a prospect's situation, so the draft already speaks to their real pain points and sounds like a person who did the work, not a template.
It's the only kind of AI worth using.
- Time to launch
25 minutes
For an ABM campaign that took 6 hours
Since using Twain, we have cut our ABM preparation time by up to 90%. Now it takes us 25 minutes instead of 6 hours to launch a campaign.
Before, our emails were like any other cold outreach message. Now, every message is unique and hyper-personalized. They sound human and help us book demos with bigger logos.
