⚡ B2B Website Contact & Tech Stack Enricher (Ultra-Fast & Memory Efficient)

Extract verified business emails, phone numbers, executive social links, DNS MX mail deliverability status, and detect complete technology stacks (CMS, E-Commerce, Payment Gateways, Analytics/CRM) across thousands of company websites at breakthrough speed.

Built for sales operations, lead generation agencies, growth engineers, and workflow automation builders (Clay, n8n, Make.com, Zapier, Python).

🚀 Why Choose This Enricher?

Traditional contact scrapers and tech detectors rely on heavyweight headless browsers (Puppeteer or Playwright). They allocate 1,024 MB to 2,048 MB of RAM per worker, crawl sluggishly at 5–10 websites per minute, crash frequently under memory pressure, and incur exorbitant cloud compute bills.

The Pure HTTP/2 Zero-Browser Breakthrough

This Actor does not launch Chrome. Instead, it utilizes an ultra-optimized HTTP/2 multiplexing crawler with automated browser TLS fingerprint emulation, paired with asynchronous RFC 5321 DNS validation and a streaming multi-vector HTML parsing engine.

✨ Key Features

1. 📬 High-Precision Email Extraction & Cloudflare Deobfuscation

• Cloudflare XOR Deobfuscation: Automatically decodes emails protected by Cloudflare Email Protection (data-cfemail="HEX" and /cdn-cgi/l/email-protection#HEX) with 100% fidelity.
• Retina & Asset Filter: 100% rejection of retina image filenames (logo@2x.png, icon@3x.webp, banner@4x.jpg), SVG icons, and media extensions falsely matched by naive regexes.
• Tracking & Dummy Email Sanitization: Automatically discards Sentry logs, Wix telemetry, Google Analytics tokens, and template placeholders (john.doe@example.com, user@domain.com).
• 100-Point Confidence Scoring Heuristic: Dynamically scores and ranks all discovered emails to select the authoritative primaryEmail:
  • +50 pts: Exact match to the company's root domain.
  • +40 pts: High-value corporate role (contact@, info@, sales@, hello@, office@, biuro@).
  • +25 pts: Cloudflare-protected email source (proves human contact intent).
  • -30 pts: Free webmail providers (Gmail, Yahoo, Hotmail).
  • -40 pts: Compliance / privacy addresses (privacy@, abuse@, legal@).

2. 🛡️ Non-Blocking RFC 5321 DNS Mail Deliverability

• RFC 5321 MX & Implicit A: Queries dedicated DNS MX records. If absent, falls back to the host's A record per RFC 5321 Section 5.1.
• RFC 7505 Null MX Detection: Immediately tags domains publishing explicit Null MX (exchange: ".", priority 0) as non-deliverable.
• Punycode / IDN Support: Seamlessly normalizes international non-ASCII domain names (e.g. münchen-consulting.de ➔ xn--mnchen-consulting-22b.de).
• In-Memory LRU Cache: 10,000-entry O(1) cache with concurrency gating (p-limit 25) prevents DNS socket exhaustion (UV_ENOBUFS).

3. 📞 Normalized Phone Numbers & Social Profiles

• E.164 Phone Normalization: Extracts international telephone numbers, automatically strips European domestic trunk zeros (0), and infers country calling codes based on TLD context.
• Executive Social Links: Canonicalizes URLs for LinkedIn (company & showcase pages), X / Twitter, Facebook, Instagram, YouTube, and GitHub organizations.

4. 💻 Zero-Browser Tech Stack Detection (19 Signatures)

Identifies core business infrastructure across 4 categories by analyzing HTTP response headers, meta generator tags, script CDNs, and inline JavaScript:

• Content Management Systems (CMS): WordPress, Webflow, Wix, Squarespace, Ghost, Drupal.
• E-Commerce Platforms: Shopify, WooCommerce, Magento, PrestaShop, BigCommerce.
• Payment Gateways: Stripe, PayPal, Klarna, Adyen.
• Marketing, CRM & Analytics: HubSpot, Klaviyo, Meta Pixel, Google Analytics 4.

5. 🔍 Autonomous Subpage Discovery & Short-Circuit

• When the homepage lacks complete contact information, the crawler automatically parses internal links and inspects up to 3 high-probability subpages: /contact, /about, /team, /impressum, /privacy.
• Short-Circuit Optimization: If the homepage already yields a verified primary email, phone number, and social profiles, subpage crawling is instantly skipped to maximize speed and preserve bandwidth.

6. 🗂️ Clean Dual-Layer Output Schema

Results are delivered simultaneously in two formats within every record:

1. Flat Root Fields: Instant, zero-friction export to Excel, CSV, Google Sheets, and Airtable without nested JSON formulas.
2. Structured Nested Objects: Rich, granular arrays and objects tailored for automation in Clay, n8n, Make.com, and custom code.

❓ Frequently Asked Questions (FAQ)

Q: How does this Actor bypass Cloudflare without a browser?

A: Cloudflare Email Protection encodes emails in hexadecimal format using XOR bitwise masking (data-cfemail and /cdn-cgi/l/email-protection#...). Traditional scrapers see only [email protected]. Our engine decodes these hex strings in memory using an 8-bit XOR cipher, recovering 100% of the original email addresses instantly without rendering JavaScript or launching Chrome.

Q: What does mxValid mean?

A: mxValid: true confirms that the domain has active, properly configured DNS Mail Exchange (MX) records (or an authoritative implicit A record fallback per RFC 5321 Section 5.1). This ensures you never send cold outreach emails to dead domains or domains that explicitly reject mail (RFC 7505 Null MX).

Q: Does this Actor comply with GDPR and CAN-SPAM?

A: Yes. The Actor only collects publicly published business contact information directly accessible on corporate websites, alongside public DNS records. No private databases or credential stuffing are employed. Users should ensure their outbound communications comply with applicable regional regulations (GDPR, CAN-SPAM, ePrivacy Directive).

Q: Can I feed 50,000 domains at once?

A: Absolutely. The Actor processes domains using streaming architecture (Actor.pushData), maintaining a flat O(1) memory footprint. Whether you input 10 or 100,000 domains, the Actor never accumulates results in RAM and will not crash.

Q: What happens if a website blocks requests with HTTP 403 or 429?

A: The HTTP/2 crawler utilizes realistic browser TLS fingerprints and includes automatic exponential backoff with randomized jitter. If a website remains permanently blocked, the Actor records status: "BLOCKED" and errorCode: "HTTP_403" rather than halting the entire job.

Q: How do I export data directly to Excel or CSV?

A: In the Apify Console run overview, click the Export button and choose CSV or Excel. All 21 flat root fields (primaryEmail, primaryPhone, cms, ecommerce, mxValid, etc.) will format into clean, separate spreadsheet columns automatically.
