FAQ

MyCQL is a B2B lead marketplace focused on high-quality, export-ready contact data across Europe — with worldwide datasets available on request.

You can browse by country, apply filters, preview lead fields, and export in standard formats for outreach and CRM workflows.

MyCQL is built around a multi-layer lead quality pipeline, not a single validation step.

While most providers only check if an email exists, MyCQL applies progressive quality controls that address technical validity, delivery risk, provider sensitivity, structural intent signals, and real-time mailbox behavior at export.

In short: most platforms validate emails — MyCQL engineers delivery probability.

Yes. MyCQL provides free evaluation downloads for new users so you can test data quality before purchasing.

Use them to review formatting, run your own checks, and test deliverability with your ESP. No payment method is required to access evaluation downloads.

We apply a 4-layer quality pipeline: baseline dataset verification (Layer 1), smart risk filtering (Layer 2), intent & entropy scoring for prioritization (Layer 3), and export-time revalidation with sender- and ESP-aware tuning (Layer 4).

This approach reduces delivery risk while ensuring exports reflect current provider conditions and the selected delivery mode (Balanced, Precision, or Expansion).

Layers are MyCQL’s 4-step data-quality pipeline:

• Layer 1 — Raw verified dataset (foundation)
• Layer 2 — Smart risk filtering
• Layer 3 — Intent & entropy scoring
• Layer 4 — Real-time revalidation & ESP Awareness before export

Most providers stop at basic validation; we engineer delivery probability.

Layer 3 analyzes email structure and domain-level patterns using non-personal signals only.

Its purpose is to rank and prioritize leads by identifying addresses that are more likely to be role-based, synthetic, or delivery-sensitive. Layer 3 does not remove leads by default and does not depend on personal tracking or enrichment.

Layer 4 is applied at the moment of export and represents the final quality control step.

It combines real-time mailbox revalidation with sender- and ESP-aware tuning, adjusting filtering behavior based on:

The destination email provider

Current mailbox response patterns

The selected delivery mode (Balanced, Safe, or Expansion)

Layer 4 ensures exported leads reflect current delivery conditions, not static or historical validation states.

Deliverable means the mailbox is likely to accept mail at the time of verification. It does not guarantee inbox placement (that depends on your sender reputation, content, and compliance).

Undeliverable indicates an email address that is confirmed invalid and cannot receive messages (e.g. invalid, rejected, or permanently undeliverable). These emails are never included in exports and do not consume credits, although they may appear in previews for transparency purposes.

A catch-all email domain is configured to accept messages sent to any address, even if the specific mailbox does not actually exist.

Unknown means verification returned no clear result (timeouts or temporary provider limits). It is neither confirmed good nor confirmed bad.

Temporary Unreachable means the email server could not be reached at the time of verification, so the email’s validity could not be confirmed right now.

“—” means the email has not been verified yet. MyCQL verifies on-demand (typically before export) so browsing stays fast and export results stay fresh.

Preview masking helps prevent scraping and abuse. You only receive the full data after purchase and export, under your account quota and acceptable-use rules.

Datasets are offered as packs by country/segment. Many customers can purchase the same pack, but exports are filtered, deduplicated, and revalidated to maintain quality and reduce waste.

CSV is the default export format. Depending on the pack, we may also support additional formats (for example Excel-compatible CSV settings).

Yes. Available filters depend on the country pack. Common filters include city/region, job/function, industry or interest tags, language, and whether a phone number is present.

Fields vary by country and source. Most packs include name and email, plus available attributes such as company, city/region, job/function, language and phone number when available.

No. We focus on data quality and deliverability signals. Results still depend on sender reputation, segmentation, offer, copywriting, and compliance.

Each purchase includes an export quota based on the pack size. Exports are generated from your chosen filters, with risk controls applied and real-time revalidation before download.

If a third-party provider is temporarily unavailable or rate-limited, exports are not blocked.

MyCQL will rely on the most recent valid verification data available at the time of export to avoid delays. If an export is affected by a temporary verification issue and the result does not meet expectations, used download units can be restored so the export can be retried.

This ensures continuity while keeping the process fair and transparent.

Refund handling depends on the case. If you encounter a technical issue or an incorrect charge, contact us with your account email and details so we can investigate quickly.
