AI Agent for Multi-Domain Email Verification

Automate the generation and verification of domain-based email candidates using Google Sheets and EmailListVerify, with results stored for scalable outreach.

How it works
1 Step
Ingest inputs
2 Step
Create and verify emails
3 Step
Log results and notify
Read the domain list and root email pattern from the Google Sheet to prepare targets.

Overview

Three sentences describing end-to-end operation and benefits.

The AI agent reads domain lists and root email patterns from Google Sheets and generates candidate addresses for each domain. It validates each candidate with EmailListVerify to identify deliverable addresses. It writes verified results back to Google Sheets and provides an audit trail for outreach campaigns.

Why you should use Multi-Domain Email Verification AI Agent

before → Struggling to collect domain emails; wasting time guessing patterns; validating emails manually; dealing with inaccurate results; storing data in inconsistent sheets. after → Consistent pattern application across domains; Automated candidate generation; Verified emails logged with statuses; Centralized audit trail in Sheets; Scales outreach with one workflow.

Before
Guesses domain emails without pattern control
Wastes time compiling candidate addresses manually
Lacks automated validation leading to deliverability issues
Suffers from inconsistent or incomplete data in sheets
Cannot easily scale across many domains
After
Consistent email pattern generation and coverage across domains
Verified emails logged as valid in Google Sheets
Invalid or risky addresses flagged for review
End-to-end data stored with a timestamp for auditability
One-click completion when domain list is processed
Process

How it works

A simple three-step flow that non-tech users can follow.

Step 01

Ingest inputs

Read the domain list and root email pattern from the Google Sheet to prepare targets.

Step 02

Create and verify emails

Generate candidate emails using the root pattern and domain, then validate them through EmailListVerify API.

Step 03

Log results and notify

Write verification results back to Sheets and notify stakeholders of completion.


Example

Example workflow

A realistic scenario showing timing and outcomes.

A growth team uploads 20 domains with the root email 'contact' and triggers the AI Agent. The agent generates five candidates per domain (e.g., contact@domain, info@domain, hello@domain, sales@domain, support@domain), validates them via EmailListVerify, and returns a validated list to the sheet within about 10 minutes.

FAQ

FAQ

Common questions about setup, usage, and outcomes.

No specialized coding knowledge is required. The agent is designed to run with a Google Sheet and an API connection to EmailListVerify. You only need to copy the template, fill in domains and root patterns, and provide a valid API key. The workflow is built for non-technical users with step-by-step prompts. You can trigger it from a single button in Google Sheets.

Processing capacity depends on your sheet size and API quota. In practice, you can process dozens of domains per run by batching them across several executions. The agent is designed to handle typical SMB-scale lists efficiently. For very large lists, you can split inputs into multiple runs while preserving results in a single sheet.

Yes. EmailListVerify is the validation engine that confirms deliverability for each generated email. Without the API key, the agent can still generate candidates but cannot reliably verify deliverability. The integration is optional only in the sense that you can disable validation, but for quality outreach, validation is recommended. You will need an active EmailListVerify account and API access to run the verification.

Invalid emails are flagged in the results sheet and can be filtered for suppression. You can review or remove them before any outreach. The status column clearly distinguishes deliverable versus non-deliverable addresses. This helps you avoid sending campaigns to bad addresses and protect sender reputation.

Yes. You specify one or more root patterns in the input sheet and the agent uses them to generate candidate addresses. You can mix patterns like contact, info, support, and sales per domain. The agent applies each pattern consistently across domains and compiles results in a single sheet. This makes it easy to tailor outreach to different ICPs.

Data resides in your Google account with access controls. The agent only reads from and writes to the specified sheet, so you control who can view or modify it. If needed, you can enable standard Google security practices like two-factor authentication and domain restrictions. We do not store data outside your Google environment in this workflow.

The results are stored in Google Sheets, which can be exported as CSV or opened in other tools directly. If you need additional formats or integrations, you can create downstream automation to pull the sheet and transform it. This keeps the primary workflow simple while allowing expansion. You can set up periodic exports as part of your outreach cadence.
