The data provider other data providers use. Emails, mobiles, and company data that don't bounce.
About us
Most B2B data is a liability dressed up as an asset. Bounced emails. Disconnected mobiles. "Verified" contacts that haven't worked at that company in three years. LeadMagic exists because we got tired of it too. We provide email addresses, mobile numbers, and company data through API and CSV upload—built for teams doing real outbound volume. No credits that expire. No contracts that trap you. Just data that connects. That's why Clay, Apollo, Instantly, Smartlead, Lemlist, Freckle, Databar and others run their hardest lookups through us. If your outbound isn't converting, it's probably not your copy. It's your data. Fix the foundation: leadmagic.io

LeadMagic reposted this
I wanted to make a post to explain what LeadMagic is, how I use it for my business, other businesses, and how you can use it for yours. (Not affiliated). A lot of databases we use, whether it's contacts already in a CRM, downloaded from Apollo/Zoominfo, have outdated, missing and invalid information. This affects deliverability, reputation, and capital if not minimized. Every time I get data from Apollo, sometimes 20% of those emails are invalid, even if it says they are valid on Apollo. Enter LeadMagic. LeadMagic has the ability to verify current contact data, and add more to it as well. This is the "Enrichment" process that I talk about in previous posts. Example: If you had a contact's email, you can verify that email. You can also find their mobile number and LinkedIn profile. What's cooler and more useful is if you have someone's LinkedIn profile URL, you can find their email and phone number. I'm yet to find something that competes with the price point of this. Their API integration is straightforward. PS: Avoid sending to "Catch-All" domains unless they're valid. It's a great way to get caught in a spam trap.

Your "perfect" email sequences are landing in spam folders. Most agencies obsess over subject lines while their technical foundation crumbles. The smart ones master deliverability before they write a single word. We just achieved 95%+ inbox placement with prospects literally saying "I've been reading your emails" on discovery calls. Here's what separates delivered emails from digital trash: 🔧 Technical Foundation: SPF, DKIM, DMARC records configured properly → Authentication protocols that ISPs actually respect 📈 Sender Reputation Strategy: Systematic warm-up progression plans → Build positive engagement history, not spam complaints 📝 Content & Messaging: Spam-proof content frameworks with dynamic personalization → Engagement-driven content that ESPs reward 📊 Engagement Analytics: Tracking systems with predictive analytics → Conversion attribution models that optimize for deliverability 🧹 Data Quality Management: Validation workflows and suppression lists → Clean lists prevent reputation damage The difference between inbox and spam folder? Spam folder: Great copy, terrible deliverability, 5% open rates, wondering why campaigns fail Inbox: Strategic technical setup, 95%+ placement, prospects reading every email Most agencies hire copywriters to fix what proper deliverability prevents. The best agencies treat email like infrastructure, not just messaging. Want the complete framework? Our 6-step Email Deliverability Excellence guide covers technical setup, reputation management, content optimization, and scaling strategies. Stop writing emails nobody receives.

Your Salesforce is a mess because you're importing data like it's 2015. Most teams create duplicate records, break field mappings, and wonder why their CRM looks like a graveyard. The pros? They follow CRUD frameworks and upsert logic. We just updated our complete Salesforce Field Mapping & Upserts Guide after fixing integrations for hundreds of revenue teams. Here's what separates clean CRMs from data disasters: ✅ 95% Dedup Success Rate: External ID matching prevents duplicate hell → Stop creating "John Smith" and "John Smith (2)" records ⚡ Bulk Processing: 10,000 records per job, 200 per batch (DML limits) → Scale without hitting governor limits 🔄 Upsert Decision Flows: Update existing, create new, validate fields → Smart logic beats brute force imports 📊 CRUD Framework: Lead → Contact → Account → Opportunity mapping → Maintain data relationships and integrity The difference between proper field mapping and winging it? Wrong way: Import everything, fix later, duplicate records everywhere Right way: External IDs, validation rules, automated dedup logic Most teams hire Salesforce admins to clean up what proper integrations prevent. The best teams treat their CRM like a database, not a dumping ground. Our updated LeadMagic × Salesforce integration automatically handles visitor identification, external ID mapping, and nurture sequence triggers. Want the technical breakdown? Our complete guide covers CRUD operations, upsert decision trees, and bulk processing strategies that keep your Salesforce actually usable. Stop treating your CRM like a junk drawer.

Your GTM stack is broken if you're still manually enriching data. Most teams waste 40+ hours per week on data entry and verification. The smart ones automate everything with APIs. We just released our complete LeadMagic API guide after helping 800+ agencies automate their entire prospecting workflow. Here's what separates automated GTM teams from manual labor: 🔧 Email Validation API: 95%+ accuracy rate, 0.05 credits per validation → Stop sending to dead emails 📧 Email Finder: Professional email discovery, 2 credits per find → No more guessing contact info 📱 Mobile Finder: Direct phone numbers, 5 credits per result→ Multi-channel outreach automation 👔 Role Finder: Find decision makers by job title instantly → Target the right people, not assistants The difference between manual enrichment and API automation? Manual: 2-3 minutes per lead, human error, inconsistent data API: 200ms response time, 95%+ accuracy, infinite scale Most agencies hire VAs to do what 5 lines of code can handle better. The best agencies treat data enrichment like plumbing - invisible, reliable, automated. Want the technical breakdown? Our complete API guide includes cURL commands, TypeScript examples, and credit-based pricing that only charges for results. Stop hiring humans for robot work.

🔥 95% of cold emails never reach the inbox 🔥 Here's Why: You're sending emails without proper authentication, compliance setup, or reputation management. Gmail & Yahoo's 2025 requirements will crush unprepared senders. Stop losing deals to spam folders. This LeadMagic cheat sheet covers the essentials that separate pros from amateurs. Authentication that actually works: ☑ SPF Setup: The foundation that prevents spoofing ☑ DKIM Configuration: Your digital signature of trust ☑ DMARC Policy: The final shield against impersonation ☑ Quick Wins: PTR, tracking domains, BIMI setup ☑ Compliance that keeps you legal: ☑ CAN-SPAM Act: Avoid $50K+ fines per violation ☑ GDPR Requirements: EU-proof your email operations ☑ List Hygiene: Clean data = higher deliverability ☑ Reputation Monitoring: Track your sender score like your credit score The reality? Most "email experts" are flying blind. They're missing SPF alignment, ignoring bounce management, and sending to dead addresses. Meanwhile, the pros using this framework are hitting 95%+ inbox rates. This isn't theory, it's battlefield-tested by the LeadMagic team. Every authentication protocol, every compliance requirement, every reputation hack that actually moves the needle. Print this. Keep it next to your desk. Your deliverability depends on it. #EmailDeliverability #LeadMagic #ColdEmail #GTM #B2BMarketing
