It validates both ASCII and internationalized email addresses, normalizes them to a canonical form, and provides detailed error messages when validation fails. The package supports configuration options for handling special cases like quoted local parts, domain literals, and SMTPUTF8 internationalization.\n\nThe validator is designed as a drop-in replacement for slower Python validators, with zero runtime dependencies and precompiled wheels for most platforms. It includes a high-performance Polars plugin for batch validation of email addresses in DataFrames, making it suitable for data cleaning and ETL workflows. The package is actively maintained and has no known security vulnerabilities.","worth_installing":"Yes, if you need fast, standards-compliant email validation. The package is actively maintained, has no security vulnerabilities, carries a permissive MIT license, and offers zero runtime dependencies. Install friction is moderate due to compiled wheels, but prebuilt binaries cover common platforms. Best suited for applications requiring high-throughput validation or batch processing with Polars; less necessary if you only validate a few emails per request."},"id":"emval","links":{"html":"https://skillfed.io/packages/emval","md":"https://skillfed.io/packages/emval.md","pypi":"https://pypi.org/project/emval/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-08-13","license_spdx":null,"license_treatment":"permissive","name":"emval","python_support":"supports_current","summary":"emval is a blazingly fast email validator"},"popularity":{"monthly_downloads":218085,"position":9345,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.1.13"}
