VerifyCORE runs every address through a 7-step verification pipeline with AI risk scoring and ESP distribution analysis. Invalids, disposables, spam traps, and risky catch-alls get flagged before they bounce. You send to real people and protect the reputation you spent years building.
Every bounce, spam trap, and complaint is a mark against your domain. Enough of them and even your good mail stops landing.
Sources: Gmail and Yahoo bulk sender requirements (2024) and industry list-decay and deliverability research (2025 to 2026). Your real exposure depends on your list, which is exactly what VerifyCORE measures.
VerifyCORE runs the full pipeline, scores the gray areas with AI, and hands you a clean list plus the intel to send it well.
Representative of the shift most senders see. Run your own list through the app to find your real starting point.
Syntax, domain, MX, mailbox, catch-all, disposable, role, and spam-trap detection run on every single row. The addresses that don't resolve cleanly get an AI risk score, so a catch-all isn't just "unknown," it's ranked by how likely it is to be real.
Two lists with the same bounce rate can behave completely differently once you know one is 70% Microsoft and the other is 70% Google. VerifyCORE breaks your deliverable addresses down by provider and gives each domain a health read, so your warmup and sending strategy matches reality.
Every address comes back tagged: safe to send, risky, or remove. Keep the deliverable segment, hold the risky one, drop the invalids, and export a clean file ready for your ESP. Your bounce rate drops, your complaints drop, and your good mail starts landing again.
Every address runs the gauntlet: syntax, domain and MX, live mailbox, then catch-all and risk scoring. What pours in raw comes out clean, so your bounce rate stays under 1% and your sender reputation holds.
