About

Bouncy is an AI-powered email verification and list hygiene platform that helps businesses clean, validate, and monitor their email lists to reduce bounce rates, improve deliverability, and protect sender reputation by removing invalid, risky, or disposable addresses before they harm campaign performance. Its verification engine performs 20+ checks per email, including syntax, domain existence, MX and SMTP validation, spam trap and disposable email detection, and role-address screening, producing detailed analytics and segmented results that let you export clean lists and focus on real contacts. It supports bulk list cleaning at high throughput, processing tens of thousands of emails per minute, and offers a real-time API so you can validate addresses at the point of capture in forms, checkout flows, or CRM imports with sub-second response times.

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.
