InboxShield spam filter for job-seeker inboxes

Filters out the spam that floods people who post in hiring threads

Problem

People who post in HN's 'Who Wants to be hired' threads report their inboxes getting flooded with spam after recent posts. Job seekers are already stressed, and now they must dig through unsolicited pitches to find real interview requests.

Solution

A lightweight email pre-filter: connect a dedicated job-search inbox, use rules plus a small model to detect bulk pitches, recruiter blasts and scam mail, quarantine high-confidence spam, and surface genuine recruiter messages with a summary push to phone.

Users

Engineers and designers who publicly post in hiring threads on HN, Reddit, and V2EX; job switchers with dedicated job-search email addresses

MVP

Email alias generation with a unified inbox; spam scoring based on sender domain, template similarity, and keywords; one-tap training (report/allow); highlighted summary view for recruiter mail; weekly spam-blocked report

Revenue

Monthly subscription during job-search season (e.g. $3/mo or $7/quarter), free tier limited to 100 emails per month; later a B2B HR edition

Why now

Public job posts attract cheap outreach bots, and exposing an email address is practically inviting abuse; small models make email classification feasible, and an indie dev can ship in one to two weeks
