Reverse Email Append Database
Every gated content download, webinar signup, and inbound form fill hands you an email address and almost nothing else — no name, no title, no way to know if that contact is worth pursuing. Infos B4B's reverse email append service flips that problem around: start with just an email, and get back a complete professional profile, full name, job title, company, direct phone, and firmographic data, matched against 86M+ verified B2B profiles. Anonymous form fills and webinar sign-ups become sales-ready, fully qualified leads in as little as 48 hours.
Every inbound touchpoint — content downloads, webinar registrations, gated whitepapers — brings in an email with almost no context attached. Reverse email append closes that gap instantly, matching each address against 86M+ verified B2B profiles so marketing and sales can score, route, and personalize outreach the moment a lead arrives, instead of researching contacts by hand.

Why reverse email append matters
Poor data quality silently undermines every campaign, forecast, and decision your revenue team makes.
You have email addresses from webinar signups, content downloads, and inbound forms — but often little else. Without knowing the contact's title, company, seniority, and phone number, you can't properly score, route, or personalize your outreach. Reverse email append transforms anonymous email contacts into fully enriched, qualified leads.
Revenue impact
Bad data costs B2B companies 15-25% of revenue through wasted effort and missed opportunities.
Reputation risk
High bounce rates damage sender reputation, pushing future campaigns into spam folders permanently.
Wasted SDR hours
Reps spend up to 30% of their time researching, cleaning, and correcting contact data manually.
Compliance exposure
Outdated suppression lists and missing opt-outs create regulatory liability under GDPR and CAN-SPAM.
Pipeline accuracy
Inaccurate contact data skews pipeline forecasts and leads to missed quota targets quarter after quarter.
CRM bloat
Duplicate and stale records inflate your CRM seat costs and make reporting unreliable across every team.

What is reverse email append?
You start with an email address, and we return the full contact profile — name, title, company, phone, social profiles, and firmographic data. It's the opposite of email appending: email in, everything else out.
What information do you return for each email?
A complete professional profile: full name, current job title, company name, direct phone number, LinkedIn profile, company size, industry, revenue tier, and headquarters location.
How accurate is the profile data?
We guarantee 90%+ accuracy on name and company fields, and 85%+ on title and phone. Every profile is cross-referenced against multiple sources — not just a single database lookup.
Can reverse append help with lead scoring?
Absolutely. By enriching anonymous email contacts with firmographic and title data, you can score leads by company size, seniority level, industry, and technology stack — turning unknown contacts into qualified prospects.
What's the typical turnaround time?
Standard reverse append delivers within 48 hours for lists under 50,000 records. Larger volumes are processed in batches with delivery typically within 5 business days.
Is there a minimum order size for reverse email append?
No minimum. We process lists from 100 to 500,000+ emails. However, per-record pricing improves significantly at 10,000+ records, so batching smaller lists together is often more cost-effective.
How do you handle personal email addresses like Gmail or Yahoo?
We can match many personal email addresses to professional profiles when the individual uses that address across professional platforms. Match rates on personal domains are lower (20-35%) compared to business domains, but we only charge for successful matches.
What security measures protect the email lists I submit?
All submitted data is encrypted in transit via TLS and at rest within our SOC 2-compliant infrastructure. We never share, resell, or repurpose your email lists, and all data is permanently deleted within 30 days of project completion.
