B2B Email Lead Generation Platform

Trust, Data Quality & Compliance

Last updated: February 6, 2026

1. What MyCQL Provides

MyCQL is a professional B2B data platform designed to support legitimate business activities such as market research, sales prospecting, and business intelligence.

The platform is intended for business and professional use only. MyCQL does not operate as a consumer directory and does not provide data for personal, deceptive, or unlawful purposes.

2. Data Sourcing Principles

Data available through MyCQL is collected from lawful and transparent sources, including:

We do not scrape private inboxes, bypass authentication systems, or collect private consumer data.

3. Email Validation & Quality Control

MyCQL uses a 4-layer quality pipeline. Each layer adds an independent control to reduce delivery risk, improve relevance, and keep exports aligned with real-world mailbox behavior.

Layer 1

Verified Dataset Foundation

  • Syntax and formatting validation to ensure structural correctness.
  • Deduplication and normalization across all datasets.
  • Domain and MX/DNS verification to confirm mailbox existence.
  • Country segmentation and structural consistency checks.

Confirms an address can technically exist at the mailbox level.

Layer 2

Smart Engagement Filtering

  • Identification of catch-all and low-engagement mailbox patterns.
  • Provider-aware filtering for ESP-sensitive domains.
  • Suppression logic for known unstable or historically weak segments.
  • Buyer-controlled exclusions applied during export.

Filters out addresses that are technically valid but statistically unlikely to engage.

Layer 3

Pattern & Authenticity Scoring

  • Analyzes email structure and domain-level patterns to detect role-based, synthetic, or delivery-sensitive addresses.
  • Scores and prioritizes leads instead of automatically removing them.
  • Enables flexible export strategies while remaining fully compliant.

Ranks leads by delivery stability and response potential — beyond simple “valid/invalid”.

Layer 4

Real-Time Revalidation & Sender-Aware Tuning

  • Performs a fresh mailbox status check at export time.
  • Adapts filtering based on destination provider behavior.
  • Aligns exports with the selected delivery mode (Precision, Balanced, or Expansion).

Final safeguard to ensure exports reflect current mailbox conditions and sender tolerance.

4. Accuracy Metrics & Transparency

Email validation results are classified using industry-standard categories, including:

These classifications are used exclusively to improve data quality and delivery outcomes.
We do not artificially manipulate metrics or inflate results. While campaign performance depends on factors such as messaging and offer quality, each export is processed through MyCQL’s 4-layer validation pipeline in real time to reduce bounce risk and improve deliverability consistency.

Built on real-world campaign feedback, MyCQL’s validation pipeline is designed to maximize delivery stability with modern email platforms.

5. Legal & Compliance Principles

MyCQL is built with compliance and responsible data use at its core. Our datasets are curated specifically for professional B2B outreach and aligned with established data protection standards.

While MyCQL applies technical and structural safeguards at the data level, customers retain control over campaign execution and are responsible for ensuring their outreach complies with local laws and regulations.

6. Responsible Use Policy

By using MyCQL, customers agree to:

MyCQL reserves the right to restrict or suspend access in cases of misuse.
