Email finder built for recruiters and talent sourcing teams

Passive candidates ignore LinkedIn InMail. Personal email outreach pulls 3 to 5 times the reply rate. Mailsfinder gives sourcing teams verified work and personal addresses for candidates and hiring managers, with 300,000 credits per cycle on the Monthly plan and 2,000,000 credits one-time on Lifetime.

Why recruiters pick Mailsfinder

Three things sourcing leads ask about first

Personal email coverage, LinkedIn-driven workflows, and an API that writes straight into your ATS.

alternate_email

Personal and work email coverage

Get both the candidate's work address and their personal Gmail, Outlook, or ProtonMail on the same row. Reach passive senior engineers in their actual inbox, not a LinkedIn notification feed they ignore.

hub

LinkedIn-driven workflow

Drop a Boolean search export, a Sales Navigator list, or a hireEZ shortlist. Mailsfinder enriches the LinkedIn URLs with verified emails in bulk so your sourcing motion stays inside the tools you already use.

terminal

API for ATS write-back

Pipe enriched candidates straight into Greenhouse, Lever, Ashby, or Workable through native Zapier, Make, n8n modules, or the REST API. No copy-paste between sourcing list and ATS.

How it works

From ICP to sequenced outreach in four steps

The same workflow for one req or a quarterly hiring plan with 30 open roles.

1

Define ICP

Build a Boolean search in LinkedIn Recruiter, hireEZ, or Gem. Capture the candidate list as a CSV of LinkedIn URLs or name + company rows.

2

Pull emails

Upload to Mailsfinder. The Finder returns work and personal addresses in bulk, tagged by source row so you can keep sourcing notes attached.

3

Verify

Every email runs through SMTP, MX, and catch-all checks. Bounce-prone addresses are flagged so your sourcing sequencer keeps a clean sender reputation.

4

Push to ATS or sequencer

Write candidates into Greenhouse, Lever, Ashby, or Workable. Or drop the verified list into Gem, Lemlist, or Smartlead for personal-email outreach.

Deep dive

LinkedIn Boolean to verified outreach list, end to end

Most sourcing teams already live in LinkedIn Recruiter, Sales Navigator, hireEZ, or Gem. Mailsfinder bolts onto the workflow you already run. Paste a Boolean export, get verified work and personal emails, push to your ATS or sequencer.

  • check_circle Bulk LinkedIn URL enrichment. Paste 10,000 profile URLs, get back a CSV with verified emails on every row Mailsfinder can resolve.
  • check_circle Dual email columns. Work address for active candidates, personal address for passive sourcing, returned on the same row.
  • check_circle Sales Navigator and hireEZ compatible. Drop in raw exports from either tool without manual column mapping.
  • check_circle Req tagging. Tag each batch by open role so sourced candidates land in the right Greenhouse or Lever pipeline automatically.

Recruiting use cases

Built for four recruiting motions teams run today

Executive search, tech recruiting, RPO delivery, and in-house TA. One credit pool, four playbooks.

workspace_premium

Executive search

Reach C-level and VP candidates on their personal Gmail or ProtonMail address. Bypass executive assistants and corporate spam filters that bury cold InMail and work-email outreach.

code

Tech recruiting

Source passive senior engineers, ML researchers, and platform leads via personal email. The audience that ignores LinkedIn aggressively is the same one that responds to a well-written personal note.

groups

RPO delivery

Run multiple client requisitions from one workspace. 300,000 credits per cycle covers heavy parallel sourcing without per-client tool billing. Lifetime plan suits long-running RPO contracts.

domain

In-house TA

Bulk-enrich ATS prospect lists with verified emails before sequencing. Find recruiter and hiring manager emails at target companies to support employer brand or poaching campaigns.

FAQ

Questions sourcing leads ask before signing up

How accurate are personal emails for passive candidates? expand_more
Mailsfinder verifies every personal address with SMTP probing, MX validation, and catch-all detection before returning it. Match rates for personal Gmail, Outlook, and ProtonMail addresses tied to a LinkedIn profile sit in the 55% to 70% range depending on the seniority and region of the candidate. Verified results are 99% accurate, which keeps bounce rates on candidate outreach under 2%.
Is Mailsfinder GDPR compliant for sourcing EU candidates? expand_more
Yes. Mailsfinder operates under GDPR-compliant data sourcing. Personal data is processed under legitimate interest for B2B and recruiting use, and Mailsfinder honors data subject requests including deletion and access. Recruiters sourcing EU candidates should include a clear opt-out and reference to your privacy policy in first-touch outreach to meet GDPR notice obligations.
Does Mailsfinder integrate with Greenhouse, Lever, or other ATS platforms? expand_more
Mailsfinder pushes verified contacts into Greenhouse, Lever, Ashby, Workable, and Recruitee through native modules in Zapier, Make, and n8n. The REST API gives sourcing engineers a direct path to write candidates into any ATS that exposes a candidate-create endpoint. Most teams enrich a Boolean LinkedIn pull, then push the verified rows into the ATS as new prospects tagged by req.
Can I bulk-enrich a LinkedIn candidate list? expand_more
Yes. Drop a CSV of LinkedIn profile URLs, first name + last name + company rows, or full Sales Navigator exports into the bulk finder. Mailsfinder processes 50,000+ rows per upload and returns both work and personal emails where available, plus verification status on each row. Most recruiters pair this with a Boolean search export from LinkedIn Recruiter or a third-party scraper.
What response rate uplift do recruiters see with personal email versus InMail? expand_more
Internal benchmarks from sourcing teams using Mailsfinder show personal email outreach pulling 3x to 5x higher reply rates than LinkedIn InMail on senior engineering, product, and design roles. The reason is simple: passive candidates filter LinkedIn notifications aggressively, while a well-written personal email lands in the inbox they actually check every morning.
Can I get both work and personal emails for the same candidate? expand_more
Yes. Mailsfinder returns work email, personal email, or both on each candidate row when available. For passive sourcing where the candidate is unlikely to read corporate mail at their current employer, the personal address is the primary outreach channel. For active candidates already in process, the work address is often more responsive during business hours.
How many credits does Mailsfinder consume per candidate? expand_more
One credit per email returned. A typical candidate lookup that returns one work email and one personal email consumes 2 credits. The 300,000 credit Monthly plan covers roughly 150,000 fully enriched candidate rows per cycle, which is enough for a recruiter running 10,000+ outreaches per month with significant overhead for failed lookups and re-enrichment.
How is Mailsfinder different from LinkedIn Recruiter alone? expand_more
LinkedIn Recruiter gives you search and InMail. Mailsfinder gives you a contactable email for the same candidate. The combination is what most modern sourcing teams use: Boolean search in LinkedIn Recruiter or hireEZ, export to CSV, enrich with Mailsfinder, then sequence personal-email outreach in Gem, Lemlist, or a custom sequencer. The two tools solve different halves of the sourcing problem.
