Deliverability Deep Check

Why is my email going to spam?

We audit your domain's entire mail infrastructure — every MX IP's blacklist status, reverse DNS (FCrDNS), SPF/DKIM/DMARC setup, and residential/hosting reputation — then our AI walks you through exactly what to fix.

Takes 10–20 seconds. We check every MX IP in parallel.

Authentication

SPF record + qualifier, DKIM selectors, DMARC policy + reporting

Reputation

Every MX IP checked against major DNSBLs, residential proxy flags

Infrastructure

PTR records, FCrDNS round-trip validation, IPv4 + IPv6

Configuration

MX redundancy, SPF lookup limits, DMARC reporting
