Bulk Email Checker is an email verification service that has been running continuously since 2012, helping marketers, developers, and data teams clean their lists and protect sender reputation before campaigns go out. The platform runs every address through a 17+ factor verification process that includes RFC syntax checks, DNS and MX record validation, disposable and role-account detection, catch-all identification, spam trap filtering, and deep SMTP mailbox verification. The system connects directly to destination mail servers in real time to confirm whether a mailbox actually exists, with a measured accuracy rate of 99.7%. Pricing is pay-as-you-go with no monthly contracts. Credits never expire and work across all tools (bulk uploader, real-time API, single-address checker). Verifying 10,000 emails costs $9.95, and rates drop to $0.0001 per email at higher volumes. That puts it 30 to 50% below the typical SaaS competitor in the category. Use cases include list cleaning before sending campaigns, signup form validation through the real-time API, lead list enrichment, and bounce reduction for transactional senders. Integrations are available for WordPress, Zapier, and n8n, with documented SDKs for PHP, Python, and Node.js. Bulk Email Checker, owns and operates its own verification infrastructure, which is why pricing can sit well below the venture-funded competition. Free single-email checks are available without an account.

Managing reactive state and dependent computations in JavaScript can get complex, especially when combining asynchronous and synchronous data. RS-X is a library that allows you to bind expressions to plain objects and makes the parts of the model used by those expressions fully reactive. Dependent computations automatically update when the underlying data changes. RS-X is framework-agnostic. While it can drive UI... - Source: Hacker News / 7 months ago
I like htmx, LiveView, React and Solid. They are great at different points, so I try to combine them in Solv (Stateless Offline-capable LiveView) and write a prototype to show the benefits. Solv's main idea is that stateless servers keep client's state in a volatile cache. It enables server components that are also interactive, which is best of both worlds between LiveView and htmx. Then fine-grained reactivity is... - Source: Hacker News / 10 months ago

In the code editor tab (powered by StackBlitz), navigate to the env.ts file and enter your OpenAI key. Run npm run generate in the terminal to see how @autoview generates TypeScript frontend code from example schemas derived from both TypeScript types and OpenAPI documents. - Source: dev.to / over 1 year ago
