Mailsie – Automatic Email

Free. Installs in 3 seconds. Your first leads in 30.

You just spent 10 minutes reading a company's website. Their team page, their blog, their contact page. Mailsie found 47 emails before you finished the About section.

That's what it does. You browse. Leads appear.

Here's how it actually works.

Install Mailsie. Sign up with Google. Flip one switch. From that point on, every website you visit is quietly scanned for publicly available email addresses and social profiles. They're organized by domain, waiting in your dashboard whenever you're ready.

Not every website will surface results — and that's by design. Mailsie only captures emails that are openly published on the page, which means every lead in your dashboard was legally and ethically obtained. No scraping behind logins, no guessing, no gray areas.

No new workflow. No tab switching. No "prospecting sessions." Just your normal research, now producing a pipeline.

Need more than one site at a time?
Drop in a list — 10 domains or 10,000. Mailsie crawls every one and comes back with emails, social profiles, and a quality score for each. Import a file, paste URLs, or pull every link from the page you're on right now. Some domains will return dozens of contacts, others may return none — it all depends on what's publicly available.

Your pipeline fills itself.
Connect your CRM once. Salesforce, HubSpot, or Pipedrive. From then on, push any batch of leads with one click. Or wire up Zapier and Make so leads flow into your sequences the moment they're found — no manual step in between.

Verified emails. Real contacts. Ready to reach.
Every email can be verified before it hits your CRM or your outbound sequence. No bounces burning your sender reputation. No ghost addresses inflating your list.

Trusted by 12,000+ sales teams.

What makes Mailsie different:
• Passive capture — finds leads from pages you're already visiting, not just pages you search for
• 100% public data — only collects emails that are openly visible on the page, keeping you fully compliant
• Bulk discovery that actually scales — 10,000 domains in one run, with pause and resume
• CRM sync that pushes verified leads, not raw scrape dumps
• Webhook-native — trigger Zapier/Make sequences the instant a lead is found
• Google Maps extraction built in — pull every business from a Maps search into your pipeline

Free plan. No credit card. No trial clock.
