You get access to a constantly growing B2B database built entirely from publicly available sources. ### 02 AI Fills the Gaps When Direct Discovery Falls Short When an email isn't publicly listed, our pattern recognition algorithms predict the most likely format like firstname.lastname@domain.com. Every predicted result includes a confidence score from 0 to 100, so you always know how reliable each contact is. ### 03 Every Email Passes Multi-Layer Verification Before You See It Before any email enters our database, it goes through DNS resolution, WHOIS lookup, SMTP verification, syntax validation, domain checks, and mailbox confirmation. Then we enrich each contact with job titles, phone numbers, social profiles, and company data. ### 04 Only 6% of What We Find Meets Our Quality Bar We reject 94% of crawled emails. Duplicates, personal webmail addresses, disposable emails, and low-confidence results are all filtered out. The result is a B2B email database you can trust because quality always beats quantity. ## What Powers Our B2B Email Database 12 specialized capabilities working across 2 billion pages every month to keep your contact data accurate and fresh: ### DNS & WHOIS Resolution Verify domain ownership and extract registration data to confirm every company in our database is real and active. ### SMTP Verification Connect to mail servers in real time to confirm each email is deliverable before it ever reaches your outbox. ### Gender Detection Identify gender from first names across cultures so you can personalize outreach and segment campaigns effectively. ### Real-Time Enrichment Get job titles, departments, seniority levels, and social profiles the moment a contact is discovered zero extra steps. ### Email Pattern Recognition Detect the email format a company uses, then predict addresses for any employee even when their email isn't publicly listed. ### Geolocation Detection Know where your prospects are country, city, and timezone so you can time your outreach for maximum impact. ### Phone Number Discovery Find direct-dial and mobile numbers from LinkedIn profiles, company websites, and email signatures.

The [Email Finder](https://tomba.io/email-finder) clearly marks whether a result is verified or predicted. You always know the origin of your data - no black boxes. 2. **Stale Data Is Automatically Removed**: After six months, we remove any contact or company information that no longer has a valid public source. Before removal, we flag it with a Removed label so you are never caught off guard. This keeps our database consistently fresh and reliable. 3. **Data Subjects Have Full Control Over Their Information**: Anyone can remove their contact information instantly by [claiming their email address](https://app.tomba.io/claim). Owners can edit any field associated with their profile. Upon a deletion request, the email and all related data are permanently and irreversibly removed. 4. **Website Owners Decide How We Index Their Pages**: Our crawler identifies itself with a clear User-Agent and fully respects the [robots.txt standard](https://en.wikipedia.org/wiki/Robots.txt). If you don't want us indexing your site, simply disallow our crawler and we stop immediately. ## Data Privacy & Compliance Every email in our database is collected from publicly available sources, in full compliance with GDPR, CCPA, and international privacy regulations: - **GDPR Compliant**: All data processing follows EU General Data Protection Regulation guidelines.
