About

Email-Validation.org is a web-based email verification service for businesses, marketers, and developers. It checks individual addresses through a REST API and accepts bulk lists through its dashboard and API, returning statuses and reasons to help users identify valid, invalid, risky, or unresolved addresses before using a mailing list. The service includes a credit-based usage model, webhooks, a JavaScript/TypeScript SDK, and a remote Model Context Protocol server for compatible AI clients. Users can validate addresses, submit bulk jobs, inspect results, and manage credits. Credits are purchased in one-time packs rather than a standard subscription; each credit covers one address, unresolved results are free, and purchased credits remain valid for 24 months. New accounts can receive up to 500 free credits, subject to signup eligibility. The service is intended for business email-list hygiene and application workflows.

About

Postcoder is an API from Allies Computing that gives developers a single endpoint for verifying and validating customer contact data at the point of entry. Used across sectors from healthcare to retail, it's built to drop into checkout, onboarding, and account creation flows with minimal friction. What's included: Address lookup – Postcode, partial address, or coordinate-based search across Royal Mail PAF, Ordnance Survey AddressBase, and 249 countries worldwide. Bank validation – Real-time sort code and account number verification, with branch data and direct debit eligibility returned in the response. Email validation – Domain and formatting checks with disposable address detection. Mobile validation – Live network status checks across 200+ countries. OTP verification – SMS-based one-time password delivery. Clear documentation, multi-language sample code, and a straightforward REST structure mean integration is quick. 30 day free trial with no credit card required.
