A-Leads ensures that every lead you unlock is real, valid, and actionable. We don’t just collect data from static databases — we verify it live in real-time using a multi-layered process, combining public sources, partnerships, human verification, and automated checks. This guarantees the highest accuracy and deliverability for your outreach.

🌐 Sources We Use

We pull and verify data from 15+ trusted public sources, including: Glassdoor, Crunchbase, Xing, LinkedIn, Wellfound, Owler, GitHub, Indeed, Docker Hub, Product Hunt, StackShare, Chrome Web Store, Craft, and more.

Additionally, we leverage:

• Public Web Crawling: corporate websites, news articles, SEC filings, press releases, government registries
• Third-Party Partnerships: public company records, business directories, social media feeds
• Human Verification: in-house research team investigates any contact info not found automatically

🕵️‍♂️ The Three Layers of Verification

1️⃣ Syntax & Format Check

Every email and phone number goes through automated checks for proper formatting.

Examples:

• Emails → Must contain “@” and a valid domain
• Phone Numbers → Correct country code and digit count

✅ This catches typos and obviously invalid data before any credits are spent.

2️⃣ Domain & SMTP Verification (Email Alive Check)

• Emails are checked against their domain to ensure the server exists
• Real-time SMTP validation confirms the address is live without sending an actual email

✅ Emails flagged as inactive or likely to bounce are excluded

3️⃣ Proprietary Catch-All Detection

Some domains accept all emails (catch-all), which can falsely appear valid.

• A-Leads uses intelligent catch-all detection to confirm deliverability
• Prevents wasting credits on emails that might bounce

📱 Mobile Numbers Verified Separately

Mobile numbers undergo carrier validation and activity checks, including:

• Format & number validity
• Line activity status
• Detecting VoIP or landlines if needed

✅ Only active mobile numbers count against your mobile credits (1 number = 15 credits)

💡 Real-Time Verification Advantage

Unlike traditional databases:

• No stale data → Every contact is verified the moment you unlock it
• No wasted credits → Invalid emails or numbers are never charged
• High deliverability & connection rates → Leads are fresh, verified, and ready for outreach

📊 Verification Results You Can Expect

• Triple-Verified Emails: <1% bounce rate
• Mobile Number Accuracy: 15–30% higher connection rates than static lists
• LinkedIn & Job Data: Cross-checked to confirm current role and company

🚀 Key Takeaway

A-Leads’ combination of multi-source data collection, live enrichment, and triple verification with catch-all detection means you only spend credits on leads that work. This ensures:

• Less wasted time chasing bad data
• Higher outreach success rates
• Confidence in every contact you unlock
