    Deliverability Platform
    Inbox Placement, Spam Testing & Reputation Signals

    Our advanced Deliverability Platform goes far beyond standard ESP reporting to give you deeper visibility, clearer insights, and actionable tools. We identify where your email program may be limited, helping restore full sending potential safely. Protect reach and prevent revenue loss caused by unseen delivery constraints.

    • Inbox placement and spam testing across 100+ global mailbox providers via seed list testing
    • Monitor IP reputation and domain reputation, blocklists, complaints, authentication, DMARC, and spam-trap hits
    • Integrate with Google Postmaster Tools and Microsoft SNDS for reputation signals
    • Surface hidden issues, spam triggers and optimization opportunities
    • Uncover opportunities to remove constraints and improve program stability
    Email Verification & Hygiene
    Real-Time Email Validation & List Accuracy

    Our email verification service ensures that only valid and safe addresses are sent. Prevent bounces and improve list accuracy and sender reputation (IP + domain) with comprehensive verification. ESP integration allows you to scan your database, lists, and segments to identify risks before sending.

    • Validates new and legacy email lists before sending
    • Prevents bounces and Sender Score damage
    • Identifies inactive or invalid user addresses
    • Integrates with your ESP data (e.g. Klaviyo)
    Bad-Domain & Spam-Trap Exclusion
    Industry-Leading Spam-Trap Protection

    By proactively removing risky domains and spam-trap threats, we prevent unseen visibility constraints from silently limiting program performance. Built from analyzing over 200+ million email addresses, our system identifies issues that traditional verification tools miss. Maintain program stability and protect existing revenue.

    • Prevents mail to spam-traps, bad/typo domains, parked or disposable domains
    • Improves inbox placement and sender reputation (IP + domain)
    • Reduces bounce rates and blocklisting risks
    • Supports smarter list management and retargeting opportunities
