High-Volume SMTP Email Verifier Build
Budget: $750 – $1,500 USD
I need a production-ready email verification system that can process well over 1,00,000 addresses on a recurring basis for my internal database
You may design the service in the language or stack you feel suits high concurrency—Node, Go, Python, Rust, or another choice is fine as long as the final result is stable and well-documented. An asynchronous architecture, queueing layer, and parallel DNS/SMTP handling are all expected.
Deliverables
• Source code for the verification engine, ready to self-host
• REST interface with clear request/response schema
• Configurable timeout, retry, and concurrency settings
• Logging and simple metrics endpoint so we can monitor throughput and error rates
• Setup instructions plus a short read-me covering scaling tips and expected hardware requirements
PS: Preferably someone who has already done it ! Since this is a prod project.
Must handle ESGS (Proofpoint, barracuda, mimecast ...)
