Verifalia is an email validation service built for developers and technical teams that need a reliable, accurate, and well-documented REST API for real-time email verification — with enterprise-grade uptime, detailed validation results, and SDKs for all major programming languages. It is the preferred choice for engineering teams integrating email validation directly into their application stack.
Product Overview
Verifalia's differentiation is its depth of technical implementation: where consumer-oriented validation tools prioritise ease of use for marketers, Verifalia is built for developers who need reliable API integration with detailed validation result codes, configurable verification quality levels, and guaranteed uptime SLAs. Its REST API returns not just a pass/fail status but a detailed classification code (Deliverable, Risky, Undeliverable, Unknown, and 20+ sub-codes) that allows developers to implement granular handling logic — for example, allowing 'Risky CatchAll' addresses to proceed with a warning, while rejecting 'Undeliverable Invalid' addresses entirely. Verifalia's quality level settings allow teams to balance accuracy against speed — Standard mode for fast bulk validation, High for maximum accuracy with additional deep-check passes, and Extreme for the most thorough validation available. Its job-based processing model submits large lists as asynchronous jobs that can be polled or webhook-notified on completion — handling any volume without client-side timeout concerns.
Key Features
- REST API with SDK Support: Well-documented REST API with official SDKs for .NET, Java, Python, PHP, Node.js, and Ruby — integrate into any application stack.
- Granular Result Codes: 20+ detailed validation result classifications beyond pass/fail — implement nuanced acceptance logic based on specific address status.
- Configurable Quality Levels: Choose Standard, High, or Extreme verification quality — balance speed vs. accuracy based on use case requirements.
- Async Job Processing: Submit large lists as asynchronous jobs with webhook completion notifications — handle any volume without timeout issues.
- Dashboard & Bulk Upload: Web interface for non-technical users — upload CSV lists and download verified results without API integration.
