Cloudmersive Validate vs mail.gw
Cloudmersive Validate
Part of Cloudmersive's unified API platform, this endpoint validates email addresses, phone numbers, VAT numbers, and domain names for syntax and deliverability under a single Apikey header. It shares the same 600-free-calls-per-month tier as Cloudmersive's other validation products in this catalog.

Its Hydra/JSON-LD REST API is rooted at api.mail.gw, exposing /domains (available disposable-email domains) and /messages collections, with no API key required for the base entrypoint.
