scraping B2B contacts legally - what's worth saving?

i'm knee-deep in setting up my B2B lead gen workflow, and i keep hitting the same wall. Right now I've got an automated filter that runs through around 700k businesses, targeting specific industries like construction or real estate. All I save is company name and email - I deliberately skip phone numbers.

two things I can't quite figure out:

First, is just company name plus email enough? Or should I bother scraping decision-maker names, website, city? Does that extra personalisation actually bump conversion rates, or is generic outreach fine? i've seen mixed results myself - sometimes a 'Hi [First Name]' makes no difference.

Second, the legal side - GDPR and all those local e-privacy laws make cold emailing a bit of a minefield here in the EU. Even though the contacts are publicly available B2B, I'm paranoid. do you send a quick, non-salesy intro asking for permission first, or go straight in with the offer? Would genuinely love to know what works in practice.

The real challenge is filtering signal from noise. I wasted months hoarding company names and job titles before realising the currency of modern B2B is intent, not contact lists. Personalisation isn't just a first name in a subject line - it's timing your message to when someone's actually paying attention.

What's worked for me is segmenting by behavioural triggers rather than static firmographics. That shift from "who" to "when" changed everything. Tools matter, but the mindset matters more: scrape sparingly, think like a publisher, not a data miner.

Oh, absolutely. People hoard B2B data like it's going out of fashion - company, role, verified contact info, intent signal, and timing. That's the gold. Everything else is just digital clutter dressed up as "comprehensive." You're not building a lead record, you're building a bloated digital corpse nobody wants to kiss.

If compliance matters, honestly just use a data provider that handles it for you. And yeah, grab the person's name at minimum - nothing screams "I don't care" louder than an email that starts with "Hi," alone. Makes you look awful.

In B2B, decision-maker name and company website carry the most weight.

Get yourself a revops person who uses Claude Code - my guy in the Philippines handles all my legal B2B scraping. 👉 Focus on job title, company size, and tech stack - that's the gold. Happy to intro you if you want a shortcut, totally worth it.

Honestly, scraping B2B contacts sounds great until you actually try to do it properly. The verification and compliance side alone turns it into more hassle than it's worth. I've switched to something like Fullenrich instead-it pulls from over 20 providers, so the emails come verified and you sidestep the whole legal grey area. Makes the process feel a lot cleaner than rolling your own scraper

Honestly, it's fine if you're careful about it. Rather than buying dodgy lists, I build my own country-specific plugins and validate everything via SMTP - gives me full control and way cleaner data. Much less nerve-wracking than trusting someone else.
