Could you build this?
Partial A web interface for bulk CSV uploads is simple, but reliable SMTP mailbox handshake verification without being blacklisted requires delicate IP reputation management and MTA networking logic.
What it would actually take: Requires a custom SMTP client worker pool running across dedicated IPs with forward and reverse DNS (PTR) set up properly to avoid spam blacklists. The hard part is handling diverse mail server behaviors, greylisting, catch-all heuristics, and preventing the verification IP pool from being permanently blocked by major providers like Google Workspace and Microsoft 365.
