What’s included

Data quality

MyCQL applies a 4-Layer quality and deliverability process before export, including syntax validation, domain & MX checks, risk pattern filtering, and suppression logic.

Real-world tests (see our Proof page) show strong inbox acceptance and engagement when data is used with proper sending practices, timing, and domain reputation. Results may vary depending on sender setup, message content, and compliance.

We focus on quality signals and transparency — not artificial guarantees.
