Why Most Cold Email Lists Are 60% Wrong

The average cold outreach list contains a huge number of contacts who were never a fit: wrong company size, wrong growth stage, no urgency, no budget signal. Without ICP fit scoring, teams email the wrong people and then wonder why nobody replies.

62%

of outreach goes to poor-fit leads

Without a tool that filters leads by ideal customer profile, most teams blast their full list indiscriminately and burn reputation on contacts that were never likely to convert.

No urgency signals evaluated
Company size not validated against ICP
Tech stack compatibility ignored entirely
47%

of send volume is avoidable waste

Every bad-fit email costs deliverability capital. That puts your domain at risk and hides the replies that could have come from genuinely qualified prospects.

Domain reputation erodes with each bad send
Spam complaints rise with irrelevant messaging
Sales time gets wasted on dead-end follow-ups

The fix is not sending more emails. The fix is sending to the right ones.

Phase I

How ICP Fit Scoring Works in Mailly

Every imported or enriched contact goes through a five-dimension evaluation. The result is a single score from 0 to 100 that decides what happens next — automatically.

Growth Stage Alignment

94/100

Matches the company's current growth phase against your target stage — seed, Series A, growth, or enterprise.

Urgency & Intent Signals

88/100

Evaluates buying intent signals like funding, hiring surges, leadership changes, competitor churn, and adoption events.

Offer Alignment

85/100

Scores how closely the prospect’s role, pain points, and priorities align with your specific offer.

Company Size Fit

90/100

Validates headcount, revenue range, and team structure against your defined ICP thresholds.

Technology Stack Compatibility

79/100

Checks stack compatibility against tools your solution integrates with, replaces, or complements.

This is what a real lead fit engine looks like: not a sequencer that sends whatever is in your CRM, but a system that validates fit before it acts.
Phase II

What Happens to Each Score

Mailly does not just score leads. It routes them automatically into the right track based on their fit result.

High Fit · 70–100

Active Sequence

Top-scoring contacts enter your primary outreach sequence immediately. These are the leads most likely to respond, convert, and justify full send volume.

Personalized intro email sent within 24h
Full sequence activated
CRM sync on first meaningful engagement
Medium Fit · 40–69

Nurture Track

Mid-range leads enter a lighter nurture flow with fewer touches and lower frequency. If intent spikes later, Mailly can automatically upgrade them.

2-touch sequence at reduced cadence
Score re-evaluated on new signal
Auto-upgrade when readiness improves
Low Fit · 0–39

Flagged & Suppressed

Low-scoring leads are blocked before sending. That protects your domain, your team’s time, and your sequencing logic from dead-end contacts.

No email sent — blocked at intake
Flagged for manual review if needed
Re-scored if enrichment data changes
Phase III

The Signals Mailly Evaluates

Mailly continuously monitors the signals that actually matter for qualification. Signal freshness is part of the scoring engine, not an afterthought.

Funding & Growth Events

Recent funding rounds, acquisitions, and expansion moves are strong indicators that a company is investing in new tooling.

Technology Stack Data

Real-time stack profiles reveal integration opportunities, replacement signals, and fit with your existing offer logic.

Hiring Velocity

Rapid hiring in target departments often signals growth, budget, and active initiative investment.

Department Headcount

Specific team size validates whether the account has the operational scale your solution actually serves.

Engagement History

Prior opens, clicks, visits, or tracked engagement increase score because they suggest awareness and relevance.

Firmographic Alignment

Industry, geography, and business model are validated against your ICP so whole wrong-fit sectors get filtered out early.

Leadership Changes

New CROs, VPs, and functional heads are often some of the highest-converting outbound trigger events.

Third-Party Intent Data

External behavior signals help identify accounts actively researching your category or competitors right now.

The principle

All eight signal categories feed into one unified ICP score. That is what makes Mailly a qualification engine, not just a scheduler.

Better targeting fixes more than reply rate

Fewer wasted sends. Better-fit conversations. Stronger pipeline.

Common Questions About ICP Scoring

Everything you need to know about how Mailly works as ICP targeting cold email software, from scoring logic to routing and implementation.

ICP fit scoring means AI evaluates every prospect against your defined ideal customer profile before any email is sent. Mailly assigns a score from 0 to 100 using company size, growth stage, technology stack, urgency signals, and offer alignment.
Mailly analyzes five core dimensions for every contact: growth stage, urgency and intent signals, offer alignment, company size fit, and technology stack compatibility. Each dimension is weighted based on your ICP definition to produce a composite score.
Low-scoring leads are flagged automatically and removed from active sequences. High-fit leads enter the main track, medium-fit leads can enter nurture, and low-fit leads are suppressed or held for review.
Yes. Mailly monitors funding rounds, tech adoption changes, relevant hiring, and leadership transitions to detect purchase readiness and surface warmer outbound opportunities automatically.
ICP scoring removes poor-fit leads before sending. That means fewer wasted emails, better relevance, stronger deliverability, and higher reply rates because your outreach reaches people who are much more likely to care.
Yes. Mailly supports account-based outreach by letting you define ICP criteria at the account level, score contacts within the account, and trigger sequences only when the account clears a minimum fit threshold.
Mailly uses funding and growth events, technology stack data, hiring velocity, department headcount, engagement history, firmographic alignment, leadership changes, and third-party intent data.
Most platforms send to everyone on your list. Mailly intercepts unqualified leads before sending, ranks purchase readiness, and routes contacts based on fit so your outreach focuses on the leads most likely to convert.
