Learning Objective
By the end of this tutorial, you’ll know how to use Email Finder & Verifier in lemlist to find missing emails, verify your existing contacts, enrich lead profiles, and prepare a cleaner list for outreach.
Why This Matters
High-quality, verified emails help you reach more prospects while protecting deliverability and domain reputation. Enriching lead data also enables better personalization, which typically improves reply rates and downstream conversions.
Prerequisites (Recommended)
You already have access to a lemlist workspace with Email Finder & Verifier available on your plan (credits included).
You have at least one lead source ready: a LinkedIn profile/search or a CSV/contact list.
You understand your team’s basic ICP fields (e.g., role, company, industry) so you can use enrichment for personalization.
Core Lesson: Step-by-Step Workflow
Phase 1: Choose the right workflow (Find vs. Verify)
Decide whether you need to find new emails or verify existing ones.
Use Find when your leads are missing email addresses (common with LinkedIn-sourced lists). Use Verify when you already have emails but want to confirm they’re safe to send to.
This decision matters because “Find” expands your reachable audience, while “Verify” reduces bounce risk and protects deliverability.
Phase 2: Find emails for leads (Enrich your list)
Prepare the minimum lead details for best match rates.
Provide as much of the following as you can: first name, last name, company name, company website URL, and/or LinkedIn profile.
More accurate input increases the likelihood of finding a correct, verified email (often 80%+ coverage depending on data quality and audience).Run Email Finder on your LinkedIn-sourced leads or uploaded list.
Start the email-finding process from your lead source (LinkedIn flow or contact list upload) and let lemlist search and return valid emails.
This replaces manual searching and reduces dependency on multiple third-party tools.Review enriched data and keep what supports personalization.
In addition to emails, use any enriched details (e.g., job title, company info, profile picture) to tailor your messaging.
The goal is to move beyond “Hi{{firstName}}
Phase 3: Verify emails you already have (Protect deliverability)
Upload or select the list you want to verify.
If you have an existing database (CSV, exports, older lists), bring it into lemlist and run verification directly inside the platform.
This helps you remove risky addresses before sending, lowering bounces and improving campaign health.Segment your list based on verification outcome.
Separate verified/usable contacts from risky or invalid ones.
This keeps your sending clean and helps you avoid wasting time and credits on contacts unlikely to deliver.
Phase 4: Turn enriched + verified leads into outreach
Use enrichment fields to personalize at scale.
Build messages that incorporate the enriched details you collected (company, role, or any relevant firmographic/context fields).
This is where Email Finder & Verifier creates compounding value: better data → better relevance → more replies.Automate the workflow to keep your pipeline fresh.
Make email finding and verification a standard step in your lead intake process (e.g., new leads → find email → verify → outreach).
This prevents “dirty list” issues from showing up only after deliverability drops.
Practical Application / Real-Life Example
Example: From LinkedIn list to ready-to-send outreach
Input: A list of 200 prospects with LinkedIn URLs, names, and company names, but no emails.
Process: Run Email Finder & Verifier to discover verified emails.
Output: A cleaned list of verified recipients plus enrichment fields (like job title/company info) you can reference in messaging.
Try-it-yourself checklist
Do you have first name, last name, and company for each lead?
Did you run Verify before sending to older lists?
Did you add at least one enriched detail to each message (role/company/context) to improve relevance?
Did you remove or exclude risky/invalid emails from sends?
Troubleshooting & Pitfalls
Issue: Low email find rate
Root cause: Missing or inconsistent input data (e.g., no company domain, incomplete names, or mismatched company names).
Fix:
Add a company website URL (domain) wherever possible.
Standardize company names (avoid abbreviations when the official brand name differs).
Include LinkedIn profile URLs when available for better matching.
Issue: You found emails, but campaign bounces are still high
Root cause: Poor email authentication setup (missing or misconfigured SPF, DKIM, or DMARC records), causing receiving servers to reject your emails.
Fix:
Set up and verify SPF records to authorize your sending domain and IP addresses
Configure DKIM signatures to prove your emails haven't been tampered with
Implement a DMARC policy starting with monitoring mode to track authentication failures and gradually enforce stricter policies
Issue: Outreach feels generic even after enrichment
Root cause: Enrichment data is collected but not used meaningfully in the copy.
Fix:
Choose 1–2 enrichment fields (e.g., job title + company) and write a sentence that shows relevance.
Create a simple personalization rule (e.g., different openers by role/industry) instead of inserting many tokens.
