RealMail
Email verification for SaaS with a single API endpoint and real-time configuration
RealMail is an email validation service for SaaS signup flows. It checks addresses for typos, invalid formatting, disposable and temporary domains, role addresses, free email domains, mail traps, fake addresses, alias addresses, and email server or DNS problems. The goal is to reduce invalid registrations and improve the quality of leads entering a product.
The service exposes a single validation endpoint, with examples for cURL, Node.js, Python, PHP, Java, and Go. After the initial API integration, configuration is managed through a web app, where users can allow or block domains, maintain allow and block lists, and adjust validation settings in real time. The platform also maintains a daily-updated database of temporary and disposable domains, and users can report domains to a shared list.
RealMail is aimed at SaaS teams that want to filter signup addresses and protect sender reputation. It is packaged as pay-as-you-go, with validation credits sold in tiers that reduce the per-validation cost as volume increases. The pages do not describe a free plan, trial, or subscription.
