How many contacts do I get for $5?

Pro includes at least 150,000 business contacts a month via 10 scrapes per day; a single scrape of a large company has returned more than 1,500 verified emails.

Are the scraped contacts verified?

Most are. Every contact comes with an MX check and a confidence grade, so you can see how solid it is before sending.

What happens after the 100 founder seats are gone?

New subscribers pay $9/month. Existing founder subscribers keep the $5 price for as long as they stay subscribed.

Any time. Access runs to the end of the period you paid for, with no refunds on elapsed periods. Payments are handled by Dodo Payments.

MailAccess — Email OSINT with every finding sourced

MailAccess is an open-source email OSINT tool that maps one email address into a full identity graph across 75 modules and 5,300+ platforms — breaches, social accounts, DNS and open-web findings. It also works as an email scraper, pulling business contacts from a company domain. Every finding shows its source, confidence score, and reasoning, and the engine is MIT-licensed for self-hosting.

Key Features

Email OSINT investigations

Submit one email address and get findings fanned into a single identity graph, powered by 75 modules covering 5,300+ platforms, with no API keys required.

Exposure scoring with corroboration

Results are scored only on corroborated evidence, combining breaches, social accounts, DNS and open-web findings into an exposure score per person.

Sourced, explainable findings

Every finding shows its source, a confidence level, and one sentence of reasoning — for example, a GitHub hit citing which modules matched and an avatar hash match.

Email scraping / lead harvesting

Enter a domain and harvest business emails from that company; Pro includes at least 150,000 contacts a month, with name, role and LinkedIn attached to every scraped contact.

Verified contacts with confidence grades

Every scraped contact comes with an MX check and a confidence grade so you can judge deliverability before outreach.

Open-source, self-hostable engine

MIT-licensed engine installable via pip, unlimited when run on your own machine, with nothing leaving your network; 1.6k stars on GitHub and 43,550+ installs.

API and CLI on Pro

Pro includes access to the /v1/enrich API and a CLI corpus panel, plus a manual scrape-on-request service answered within 48 hours.

Six export formats

Investigation reports can be exported in six formats on the hosted plan.

How It Works

Investigate an email

Run an email address through 75 OSINT modules; the tool returns an identity graph of connected accounts, breaches and open-web findings, each with a source and confidence level. On the hosted free tier, your own email always gets the full report, while other people's emails return a preview.

Scrape a domain

Enter a company domain and the scraper harvests verified business emails from it, with name, role and LinkedIn where available (Pro). A single scrape of a large company has returned more than 1,500 verified emails.
