Built a B2B email extractor - feedback?

liamcopy

I got sick of manual scraping.

So I built a tool. A web-based Email Finder & Deep Business Extractor.

You drop a Google Maps export (or any CSV) into the dropzone. It scans company homepages. Then deep-scans subpages on the server. Finds corporate email addresses.

If you have the company name and city but no website? It auto-finds the website first.

Clean interface. Built-in feedback form. Completely free right now.

But someone said it best: extractors are everywhere now. The real bottleneck is finding people who actually want to be emailed.

Fair point. Maybe that's my next project.

Before I share the URL wide, I want honest thoughts.

Does a tool like this solve a bottleneck in your workflow?
What features would make this a must-have for lead gen?
What platforms do you struggle to scrape?

Let me know. I'll send you the link.

Oh brilliant, another scraper. the real trick isn't hoovering up emails - it's finding the handful of humans who haven't trained their spam filter to yeet you into the void before you even hit send. anyone cracked that algorithm yet?

this is where the rubber hits the road. Finding the email address is easy, knowing whether it's worth contacting is the whole game. If you're serious about keeping bounce rates low and deliverability high, I'd add three things:

Inbox validation - run the list through NeverBounce or ZeroBounce at collection time, not after export.
Source URL tagging - store exactly where each address came from (LinkedIn, company site, GSC backlink). that makes deduping trivial and lets users prioritise.
Role-based detection - separate info@ and support@ automatically. Anyone running cold outreach knows those kill open rates.

Bonus points if you can layer on basic firmographic enrichment (industry from the domain, employee count from Crunchbase). If the export is clean - deduped, verified, and tagged - I'd switch from my current Screaming Frog + Hunter combo in a heartbeat.

Interesting project - manual scraping is definitely where a lot of workflow pipelines break down. The auto-find website feature sounds useful for supplementing datasets that aren't structured for import.

The real bottleneck, as you've hinted, is verification. I've seen Apollo return decent find rates too, but that 10% bounce threshold is painful when you're pushing into a CRM at scale. For my own exports I've been leaning on a tool that does real-time SMTP verification on the extracted contacts - it sits between the scrape and the send layer. You still need a separate sender (Smartlead or similar) because it doesn't handle delivery, but the data quality is night and day. Deliverability hovers around 98% on the cleansed lists.

The key takeaway for anyone building something like this: verification isn't a nice-to-have, it's what separates a useful extractor from an inbox-killer. If you can integrate a verification step directly into the pipeline (even a lightweight SMTP check), you'll save users weeks of reputation damage

haha, yeah. that tool would've saved me hours of manual grinding last month

no one actually wants unsolicited emails, do they? 😄 That's the eternal contradiction of outbound-we all hate receiving them but still have to send them.

Built it for myself first.

Honest truth? That's the best way to launch anything.

Solving your own pain means you actually care about the edge cases.

So making it free for others? Smart move. Feedback loop turns a good tool into a weapon.

You get data. We get a working extractor. Everyone wins.

What's next on the feature list?

Definitely seen worse ideas. The amount of people still manually scraping outreach lists like it's 2005 is genuinely baffling. Honestly, if you've built a tool that actually works and doesn't just pump out garbage, drop me a line. I've got a few client accounts that could use a cleaner start.

Haha, i feel you.
Gave your tool a go last night... proper impressed.
If you want another set of eyes on it, I'm happy to give honest feedback.

mate, I'm always down to see what disaster someone's cooked up in their spare time. DM me the deets and I'll give it the stink eye-hopefully in a good way
