Mailhorn Reviews & Product Details

ScoreHQ is a campaign management and sending platform built specifically for high-volume email operators who run their own MTA infrastructure. Unlike traditional ESPs that bundle sending infrastructure with marketing tools, ScoreHQ is purpose-built as the sending and intelligence layer that sits on top of MTAs like Sendgrid, KumoMTA, Aamazon SES, Mailgun PowerMTA, Postal etc. — giving teams full control over their delivery stack while removing the operational burden of building campaign tooling in-house. The platform is designed for teams that send millions of emails per day and need real-time visibility into deliverability, granular sub-list management, and multi-tenant sending capabilities. ScoreHQ is built on ClickHouse to deliver real-time analytics at scale, so operators can monitor campaign performance, bounce patterns, engagement, and inbox placement signals as events happen — not hours later. Who it's for ScoreHQ is built for affiliate marketers, lead-generation businesses, agencies managing multiple sender brands, and any operator running high-volume email programs (1M+ sends per day) who has outgrown traditional ESPs and runs their own sending infrastructure. If your team owns the MTA but is tired of stitching together internal dashboards, deliverability scripts, and FBL parsers, ScoreHQ replaces all of that with a single platform. Core capabilities: Campaign management and scheduling for high-volume sends Sub-list management and segmentation Multi-tenant sending with per-tenant isolation Real-time deliverability intelligence and analytics Feedback loop (FBL) processing and bounce handling Integration with self-hosted MTAs (KumoMTA, PowerMTA, Postal, and others) How ScoreHQ is different ScoreHQ does not replace your MTA, and it is not a managed sending service. It is the modern campaign and intelligence layer for operators who already own their infrastructure — a more accessible, real-time alternative to legacy tools like Ongage, without the all-in-one bloat of platforms like Klaviyo or Braze.
