My neighbor got a new job in November. Great news. He stopped actively searching in October, updated his LinkedIn, moved on.

It’s now March. He’s still getting four to six recruiter emails a day to his personal Gmail. Not from companies he applied to. From recruiters who somehow got his address from job boards he signed up for six months ago, who sold or shared that data with staffing agencies, who passed it along to other recruiters, who apparently never expire a contact from their CRM list regardless of whether the person is still looking.

This post is for anyone who is actively job hunting right now — or about to start — and wants to actually control what happens to their contact information during the process. Specifically the person who signs up for Indeed, Glassdoor, ZipRecruiter, and two or three niche job boards, uploads a resume, and then wonders six months later why their inbox has become a full-time job in itself.

Here’s what actually happens. Most job boards are free to candidates because the revenue model runs on the employer side and, increasingly, on the data side. Your resume, your job preferences, your search history on their platform, and your email address are all logged. Some of that data gets shared with “hiring partners” — which in practice means staffing agencies and recruiting firms who pay for access to candidate pools. Your contact info doesn’t disappear when you find a job. It sits in databases and gets worked for months or years.

So the fix is actually pretty clean. For job boards where you’re just browsing listings, saving jobs, and setting up alerts — use a temp Mail On Deck address. The alerts land in the temp inbox, you check them when you want, nothing touches your real email.

For actual applications and interviews — use your real address. Obviously. You need reliable, two-way communication with a hiring manager, and a temp inbox that might expire mid-process is not the right tool for that. The separation is the whole point: browsing and alerting on temp, real conversations on real email.

It’s not a perfect setup. Some job boards require account verification and will occasionally flag temp domains. When that happens, I generate a new Mail On Deck address on a different domain and try again — it’s a two-minute fix. If a site persistently rejects every temp address I throw at it, I move on. There are enough job boards that I don’t need to fight any specific one for the privilege of receiving their alerts.

The Economics Behind Why They Want Your Email

Job boards do not exist to help you find a job. I mean, that’s a side effect. But the actual business model is selling access to candidates — to employers, to recruiters, and in some cases to staffing firms that pay subscription or per-contact fees to reach people actively looking for work. Your email address, attached to a resume and a set of job preferences, is a high-value record. It tells them your industry, your seniority level, your location, your approximate salary range, and the fact that you’re currently open to offers. That profile is worth money. Not to you. To everyone who wants to sell you something adjacent to employment.

The mistake most job seekers make is treating their primary email like the only option. It’s not. The mistake after that is using a Gmail alias — yourname+jobs@gmail.com — thinking it creates separation. It doesn’t. The alias tag gets stripped automatically by recruiting CRMs (Greenhouse, Lever, Workday — all of them normalize email addresses on ingestion), so your base address is fully exposed and now lives in a recruiter’s outreach sequence. You’ve done the work of an alias with none of the actual protection.

We ran a test at Mail On Deck in January. Created 8 fresh temp addresses and registered accounts on 8 major and mid-tier job boards — general boards, one tech-specific board, one remote-only board. All 8 verification emails arrived within 90 seconds. Over 28 days, those 8 inboxes received 312 emails combined. Only 94 were actual job alert notifications matching the search criteria we set. The remaining 218 were recruiter outreach, sponsored job promotions, premium upgrade pitches, salary report downloads requiring “just a quick form,” and in three cases, emails from third-party HR software platforms we never directly signed up with.

Recruiting CRMs don’t expire contacts just because you found a job, so the only inbox that stays clean is the one you never gave them in the first place.
