Who to email

Targeting does more for results than any sentence you write. How to define an ideal customer profile, build honest segments, time outreach with triggers, and keep lists clean.

11 min read · Course overview

Objectives

In this module

  • Write an ideal customer profile with firmographic, situational, persona and exclusion criteria.
  • Build segments small enough that one true reason for writing fits everyone.
  • Use triggers to time outreach.
  • Explain the legal and deliverability risks of scraped and purchased lists.
3.1

Most of your audience isn't buying

Research for LinkedIn's B2B Institute estimated that only around 5% of a category's B2B buyers are in the market at any given time; its author, John Dawes, cautions that the ratio isn't precise or universal [1]. Buyers also do more of the work themselves: in a Gartner survey published in March 2026, 67% of B2B buyers said they prefer a rep-free buying experience [2].

Two practical consequences follow. Most people you email cold are not looking right now, which argues for low-pressure asks (Module 4). And timing matters: reaching someone when something has changed for them beats reaching them at random.

3.2

Smaller, tighter segments

Woodpecker's benchmark found campaigns of up to 50 prospects had a 2.7% median reply rate, against 1.2% for campaigns of 1,001–5,000 [3]. That isn't proof that batch size itself matters. Small campaigns probably also get more research and more relevant messages. But it is consistent with what every experienced sender says: relevance scales badly.

The test for a segment is simple. Can you write one honest sentence explaining why you are writing that is true for every person in it? If not, split it. Note that the law points the same way: France's CNIL, Canada's CASL and Australia's Spam Act all hinge on relevance to the recipient's role [4,5,6].

3.3

Writing an ideal customer profile

There's no rigorous study of ICP method, so treat this as a structured checklist rather than a formula. A usable profile covers:

  • Firmographics: industry, headcount, revenue band, geography.
  • Technographics: tools they already run that make you relevant (or irrelevant).
  • Situation: what is happening to them, such as funding, hiring, a regulatory deadline, a migration.
  • Persona: the role, seniority and the specific problem you solve for that person.
  • Exclusions: current customers, open opportunities, competitors, and anyone who has opted out.
Example profile
Firms: US registered investment advisers, 10–50 staff.
Situation: hired a first marketing or BD person in the last 90 days.
Persona: the new hire, and the managing partner who hired them.
Problem: outreach with no record-keeping or review process.
Exclude: current customers, firms in an active deal, prior opt-outs.
3.4

Triggers and intent signals

Common triggers include a past champion changing jobs, a new executive hire, a funding round, hiring for roles your product supports, a change of tools, and regulatory deadlines. They give you a true, specific reason to write now.

Most of the evidence for triggers is vendor-reported. UserGems, which sells job-change data, reports a 4.5% response rate on the first step of its own job-change sequence [7]. No independent study compares trigger-based with untimed outreach, so treat triggers as a strong heuristic rather than a proven multiplier.

3.5

List quality

Contact data goes stale as people change jobs, but the widely quoted decay percentages don't trace back to an accessible study. Your own bounce data is the real measure. Verify lists shortly before sending and re-verify anything more than a few months old.

Scraped and purchased lists carry three risks at once. Legally, third-party lists don't give you consent under CASL [5] and are excluded from the UK soft opt-in [8]. They hurt deliverability: Spamhaus specifically calls out scraping, and such lists contain spam traps [9]. And they bounce.

Key takeaways

Remember this

  • Only a small share of your market is buying now, so time outreach and keep asks light.
  • A segment is right when one honest reason for writing fits everyone in it.
  • Write exclusions into the ICP, not just inclusions.
  • Triggers give you a true reason to write; treat vendor lift figures cautiously.
  • Bought and scraped lists are a legal, deliverability and quality risk at once.
Exercise

Write one ICP and one segment

Keep it to a single page.

  1. Step 1

    Write your ICP using the five headings above, including at least three exclusions.

  2. Step 2

    Pick one trigger you can actually observe for that ICP, and where you'd see it.

  3. Step 3

    Build a segment of 50 or fewer contacts that match the ICP and the trigger.

  4. Step 4

    Write the one-sentence reason for writing, and check it is true for every contact. Remove anyone it doesn't fit.

Recommended contacts

When you build a campaign, describe your target customer and AngelSend ranks your existing contacts by fit and explains each match, with a minimum-fit setting.

Segments and exclusions

Save filtered views and segments on the Contacts page; a campaign can automatically skip anyone previously contacted and anyone on an uploaded suppression list.

Signals

The Signals page ranks your hottest contacts over the past 30 days by weighted signal score, with a feed of buying signals.
