Automate Professional Email Verification for Leads
detail.loadingPreview
This n8n workflow automatically extracts the domain from an email address and verifies if it's a professional (corporate) email or a generic free one. It's designed to help qualify leads and maintain a clean contact database by identifying and flagging common free email addresses.
About This Workflow
Elevate your lead qualification and data hygiene with this powerful n8n workflow for professional email verification. By automatically extracting the domain from any email input, the workflow then cross-references it against an extensive, pre-populated list of common free email providers. This allows you to instantly distinguish between professional corporate emails and generic free accounts (like Gmail, Outlook, etc.). Ideal for sales, marketing, and operations teams, this automation ensures you're engaging with high-quality leads, reducing spam, and improving the effectiveness of your outreach campaigns.
Key Features
- Automatic Domain Extraction: Seamlessly extracts the domain (e.g.,
example.com) from any given email address. - Extensive Free Email List: Compares the extracted domain against a comprehensive, built-in list of hundreds of free email service providers for accurate identification.
- Professional Email Identification: Clearly flags whether an email belongs to a corporate domain or a free service.
- Customizable Verification Logic: The
Codenode contains a customizable list of free email domains, allowing you to update or extend it as needed. - Seamless Integration: Designed to integrate into any larger workflow where email validation is critical, such as lead capture forms or CRM updates.
How To Use

$json.body.email. - Configure "Get domain from email" Node: This
Setnode automatically extracts the domain from$json.body.emailand stores it in a new variable nameddomain. No changes are typically needed if your email input matches the expected path. - Customize "Verify professional email" Node:
- Update the
freemail_list: Inside theCodenode, you'll find a JavaScript arrayfreemail_list. You can add or remove domains from this list to tailor it to your specific needs. - Implement Verification Logic: Add JavaScript code within this node's
jsCodeparameter to compareitem.json.domain(the domain extracted in the previous step) against thefreemail_list. A common approach is to set an output variable likeitem.json.isProfessional = !freemail_list.includes(item.json.domain);.
- Update the
- Utilize the Output: Connect subsequent nodes to process the verification result. For instance, use an
IFnode to branch your workflow based on theisProfessionalvariable, sending professional leads to one path (e.g., CRM update) and free email leads to another (e.g., nurturing sequence or discard).
