DeliverCORE is the email deliverability platform that watches every send. Sender reputation monitoring, blacklist and DMARC monitoring across 90+ lists, inbox placement testing, and email warmup. One dashboard that watches every email and tells you the second something breaks.
You send it. Your platform says "delivered." Whether it reached a human is a different question, and most senders have no way to answer it.
Sources: Validity and Unspam 2025 deliverability benchmarks, plus DMARC enforcement data (2025 to 2026). Your real exposure depends on your domains, which is exactly what DeliverCORE measures.
DeliverCORE is an email deliverability platform that pulls authentication, blacklist and DMARC monitoring, inbox placement, and email warmup into one view, then alerts you the moment any of it slips.
Representative of the shift most senders see. Run your domains through the free tools below to find your real starting point.
"Delivered" is not "seen." DeliverCORE runs your mail through seed accounts across Gmail, Outlook, Yahoo, and Apple, and tells you the truth: primary inbox, promotions, or spam. You stop guessing and start fixing.
A blacklist hit can tank a whole domain overnight, and most senders find out from angry customers days later. DeliverCORE watches 90+ lists in real time, alerts you instantly, and starts the delisting process before the damage spreads.
Most deliverability problems trace back to two things: authentication that was never finished, and domains sent at full volume before they earned trust. DeliverCORE manages SPF, DKIM, and DMARC to enforcement, then warms new domains on a schedule so you build reputation instead of burning it.
DeliverCORE tracks your sender score across every mailbox provider, day and night. When something threatens it, a blacklist hit, an auth failure, a spike in complaints, you catch it before it touches your campaigns.
Seven free diagnostics we built and run ourselves. The same checks power DeliverCORE. Run yours in seconds.
Multi-tenant from the ground up. Manage every client domain under one roof, set per-client alerts, and hand over clean white-label reports with your logo, not ours. Deliverability becomes a service you sell, not a fire you fight.
