More of your buyers now read email through an AI email assistant that summarizes threads, sorts the inbox and drafts replies. Talk about personal agents rose 57% in October 2026, according to Adam Schoenfeld's October AI x GTM report, and LinkedIn's Trust Advantage research says "94% of buyers now use AI at every stage of the process."
When an assistant compresses your cold email into one line, the clever opener is gone. What survives is who you are and who sent you. A warm intro from someone the buyer already knows is the strongest version of that line.
What does a buyer's AI email assistant do to a sales email?
Most assistants do three things: summarize long messages, group or prioritize the inbox, and suggest a reply. Each one strips the parts of a cold email that were written to win attention.
A personalized first line becomes "a vendor is asking for a meeting". A subject line trick disappears into a one-line summary. The suggested reply for an unknown sender is usually a polite no, or nothing.
Executives were already the hardest to reach: Gong Labs found "C-level executives are 30.2% less likely to reply to cold emails than non-executives." An assistant in front of them does not make that easier.
What survives the summary: cold email or a warm intro?
Compare the facts an assistant can pull out of each message. These are the facts a busy buyer sees first.
| What the assistant extracts | Cold email | Forwarded warm intro |
|---|---|---|
| Who is this from? | Unknown sender at a vendor | Someone the buyer knows, plus the person they vouch for |
| Why me? | A guessed trigger, often generic once summarized | A named relationship and a specific reason |
| Is there history? | No prior thread | An existing thread with a known contact |
| What is the ask? | A meeting with a stranger | A short call the mutual contact suggested |
| Likely suggested reply | Decline or ignore | Accept, or reply to the person who made the intro |
LinkedIn's research points the same way: "The signals most predictive of a positive reply are content engagement, profile views, or shared mutual connections." A shared connection is one of the few signals that still reads clearly after a machine has rewritten your message.
How do you write an intro that survives an AI summary?
Write the intro so the most important facts are in the first two sentences, in plain words. An assistant summarizes from the top, and so does a busy human.
- Lead with the relationship. "Dana, Priya here. We worked together at Northwind." The tie is the reason to read on.
- Name the person and the reason in one line. "I'd like you to meet Sam, who runs revenue at Lexora. He is working on the problem you raised at the offsite."
- Make the ask small and specific. "Worth a 20 minute call in the next two weeks?"
- Keep the vendor pitch out of it. The connector vouches for the person. The product details can wait for the call.
- Send it from the connector's own thread. A forward from a known sender is treated very differently from a new message from a stranger.
Forwardable intro template (copy and edit)
Subject: Intro: Sam (Lexora) to Dana
Dana, hope the quarter is going well. I'd like to introduce Sam, who leads revenue at Lexora. We worked together for three years and I trust his judgment.
He is working on how teams like yours reach executives at new accounts, which came up when we spoke last month. Would you be open to a 20 minute call with him in the next two weeks?
Sam is copied. I'll let you two take it from here.
Priya
Names are fictional. The first two sentences carry who, why and the ask, so they survive any summary.
Who should send it?
The best sender is the person the buyer is most likely to read: a former colleague, a customer they trust, a board member or an investor. The worst sender is a rep the buyer has never met, however good the copy.
Finding that person is the hard part. That is the job of connector discovery: map who on your team and in your customer, board and partner networks knows the buyer, with the evidence for each tie. For the asking itself, see how to ask a customer for a referral intro.
What can you do this week?
- Pick ten target accounts where your cold emails to executives get no reply.
- For each, list anyone on your team, your customers, your board or your investors who knows someone there.
- Rewrite your intro request so the first two sentences carry the tie, the person and the ask.
- Route each ask to the person the buyer is most likely to read, with the rules in our intro request orchestration guide.
- Track which intros turned into meetings, so you know which connectors to ask again.

Setup is about 60 minutes of technical setup, graph in under a day, full go-live in about a week.
Frequently asked questions
Do AI email assistants filter out sales emails?
Most assistants summarize, sort and suggest replies rather than block mail outright. The effect is similar: a cold pitch from an unknown sender gets compressed to one line and a suggested decline. Messages from known contacts, or forwards from them, keep their context and are easier to act on.
Why does a warm intro work better when buyers use AI assistants?
An assistant keeps the facts and drops the persuasion. In a warm intro the key facts are a person the buyer knows, a specific reason and a small ask, and all three survive a summary. In a cold email the persuasion was the point, so less survives.
How long should a warm intro email be?
Short enough that the first two sentences carry who is writing, who they are introducing, why it matters to the buyer and the ask. Three short paragraphs is plenty. Leave product detail for the call, since the connector is vouching for a person, not a product.
Who should send the intro?
The person the buyer is most likely to read and trust: a former colleague, a customer, a board member or an investor. Choose by the strength and recency of the tie, not by seniority alone, and respect each connector's preferences on how often they are asked.
