Find Personal Email

Deepline’s personal email waterfall tries 3 providers — Dropleads, LeadMagic, and PeopleDataLabs — to resolve consumer email addresses from professional identifiers like LinkedIn URLs and names. Just describe what you need in natural language and Deepline handles provider selection automatically. Personal emails survive job changes, domain switches, and corporate reorgs. B2B data decays at roughly 22.5% per year (HubSpot via Cognism), so personal emails are a more stable channel for ABM advertising and direct outreach.

How do I find personal emails with Claude Code?

Tell Claude Code your use case and input data. Deepline routes to the personal email waterfall and resolves consumer email addresses from LinkedIn URLs, names, and other professional identifiers.

​
What does the personal email waterfall do step by step?

The waterfall reads your contact list, tries 3 providers in cost order, and returns personal (non-work) email addresses. Each provider resolves consumer emails from professional identifiers. The multi-provider approach increases your odds of getting fresh data, since B2B data decays at roughly 22.5% per year (HubSpot via Cognism).

​
Which providers does the personal email waterfall use?

The personal email waterfall uses 3 providers: Dropleads, LeadMagic, and PeopleDataLabs. They run in cost order, and the lookup stops at the first valid personal email. 
deepline enrich --input contacts.csv --output contacts-personal.csv \
  --with '{"alias":"personal_email","tool":"person_linkedin_to_email_waterfall","payload":{"linkedin_url":"{{linkedin_url}}","first_name":"{{first_name}}","last_name":"{{last_name}}"}}'
Deepline routes to the appropriate provider chain based on your input data.
Compliance note: Personal email regulations vary by use case. Ad targeting (LinkedIn Matched Audiences, Facebook Custom Audiences) has broader permissibility than cold outreach. Check your jurisdiction’s rules before using personal emails for outbound campaigns.

Frequently Asked Questions

​
What is the difference between finding a work email and a personal email?

Work emails are corporate addresses (e.g., sarah@stripe.com) used for B2B outreach. Personal emails are consumer addresses (e.g., sarah.chen@gmail.com) used primarily for ad targeting on platforms like LinkedIn Matched Audiences and Facebook Custom Audiences. Deepline has separate waterfall tasks for each, using different provider chains optimized for the email type.

​
Can I find personal emails in bulk from a CSV?

Yes. Tell Claude Code “find personal emails for contacts.csv” and Deepline reads your column headers, selects the personal email waterfall, and enriches every row. The personal email waterfall works best when you provide LinkedIn URLs alongside names. Always pilot with 3-5 rows first.

​
How accurate is personal email lookup?

Hit rates are lower than work email lookups because consumer data is less systematically indexed. A LinkedIn URL significantly improves match rates. Waterfall enrichment gets 20-40% higher coverage than any single provider (Instantly). Ad targeting (LinkedIn Matched Audiences, Facebook Custom Audiences) generally has broader permissibility than cold email outreach. Regulations vary by jurisdiction — CAN-SPAM (US), GDPR (EU), and CASL (Canada) each have different requirements for personal email marketing. Always check your jurisdiction’s rules before using personal emails for direct outbound campaigns.

​
What data do I need to find a personal email?

For the best results, provide a LinkedIn URL plus first and last name. Deepline can also work with just a LinkedIn URL or just a name and company, but match rates are highest with LinkedIn URLs.
