Mailerio
RiskMail.io is an email and domain risk intelligence API designed to help SaaS platforms, marketplaces, fintech products, affiliate networks, e-commerce websites, and online communities reduce fake signups, disposable email abuse, and low-quality registrations.
Unlike basic email validation tools that only check format or deliverability, RiskMail focuses on practical risk signals that are useful during registration, onboarding, lead capture, checkout, and fraud prevention workflows.
With RiskMail, developers can check whether an email address or domain is associated with disposable email services, temporary inbox providers, free email providers, risky MX infrastructure, suspicious shared MX patterns, or other domain-level risk signals.
The API returns a simple, developer-friendly JSON response including verdict, disposable status, free provider status, risk level, risk score, domain information, and reason. This allows teams to automatically allow, review, or block signups based on their own risk policy.
Common use cases include preventing fake accounts, reducing free trial abuse, improving lead quality, protecting signup forms, detecting temporary inboxes, validating affiliate traffic, and adding email/domain risk signals to an existing fraud prevention stack.
RiskMail is built for developers and product teams that need a fast REST API for email risk checks and domain risk intelligence without building and maintaining their own disposable email database or domain classification system.
Key features: - Disposable and temporary email detection - Domain risk intelligence - Free email provider detection - Risk scoring - Allow / review / block verdicts - MX-related risk signals - JSON REST API - Signup fraud prevention - SaaS and marketplace abuse protection
RiskMail is useful for any platform that wants to stop low-quality or risky users before they enter the system.

RiskMail.io's answer:
RiskMail focuses on email and domain risk intelligence instead of only basic email syntax validation. It helps developers detect disposable emails, temporary inboxes, free email providers, risky domains, suspicious MX infrastructure, and signup abuse signals through a simple REST API.
The API returns practical decision fields such as verdict, risk level, risk score, disposable status, free provider status, and reason, so platforms can decide whether to allow, review, or block a signup.
RiskMail.io's answer:
RiskMail is designed for developers and product teams that need a simple way to reduce fake signups, low-quality leads, and temporary email abuse.
Compared with basic email validation tools, RiskMail provides risk-focused signals that are useful for SaaS onboarding, marketplaces, affiliate traffic, lead forms, and fraud prevention workflows. It is easy to integrate, returns structured JSON, and can be used directly in backend registration or verification flows.

RiskMail is built for SaaS companies, marketplaces, fintech products, affiliate networks, e-commerce websites, online communities, developer platforms, and fraud prevention teams.
The primary users are developers, product managers, growth teams, and security teams that want to improve user quality and reduce fake registrations before users enter their platform.
RiskMail.io's answer:
RiskMail was created to solve a common problem faced by online platforms: many registrations use disposable emails, temporary inboxes, or low-quality domains that pass basic email format checks but still create fraud, abuse, or poor lead quality.
The goal of RiskMail is to provide a practical API that helps platforms identify risky email and domain signals early in the signup or onboarding process, without having to build and maintain their own disposable email database or domain risk classification system.
RiskMail.io's answer:
RiskMail is built as a modern backend API service using Go, PostgreSQL, Redis, REST APIs, and JSON-based responses.
The platform is designed for fast email and domain risk checks, API key authentication, usage tracking, rate limiting, and scalable backend integration.
RiskMail.io's answer:
RiskMail is currently used by early-stage developers, SaaS builders, and online platforms testing email and domain risk detection for signup protection and lead quality improvement.
