Spam filtering, built to data-governance standards.
Blockjay is made by Canyon Data Insights, a specialist master-data-management and data-quality practice led by a senior data architect with 20+ years in the field.
It's the same discipline behind Canyon's client work for regulated, data-heavy organizations — the matching rules, profiling, survivorship logic, and governance that decide what an organization can actually trust about its own data.
Blockjay came from pointing that discipline at everyday email. In master-data work the rules are strict: never lose the source of truth, know exactly what you have, keep humans accountable for the calls, and govern tightly what data is exposed. Consumer spam filters break every one of them — they delete real mail, they can't tell you why they flagged something, and they ship your private messages off to be mined.
Spam filtering held to data-governance standards.
The same rules Canyon lives by in master-data work — applied to your inbox.
Never lose the source
It sorts your mail, never deletes it — everything is saved in full and restorable in one tap.
Know what you have
Every verdict comes with a score and a one-line reason. No black box, no guessing why.
Keep humans in control
One tap corrects any call — and your corrections are what train your filter.
Govern what's exposed
We send AI only the minimum needed to classify the uncertain few — never your whole mailbox — under a zero-retention, no-training agreement.
Twenty years keeping data trustworthy for banks, hospitals, and manufacturers — now applied to your inbox. Automated insights through governance and quality.
