Overview

End-to-end email hygiene for campaigns and onboarding.

The AI agent reads the subscriber list from Google Sheets and normalizes fields for consistent processing. It validates emails with VerifiEmail to determine deliverability and risk, and classifies each entry as keep, remove, or tag. It deletes invalid rows, creates the CleanSubscribers sheet with all valid emails, and returns a structured JSON summary for auditing and integration.

Process

How it works

A simple, non-technical three-step flow.

Step 01

Fetch & Normalize

Reads subscribers from Google Sheets, parses fields, and standardizes formats for reliable validation.

Step 02

Validate Emails

Performs real-time checks with VerifiEmail, including MX records, disposable domain detection, and provider data.

Step 03

Classify & Sync

Classifies each subscriber as keep/remove/tag, deletes invalid rows from the source, appends valid ones to CleanSubscribers, and returns a JSON summary.


Example

Example workflow

One realistic scenario.

Task: Clean a batch of 1,200 subscribers via webhook. The AI agent fetches 1,200 rows from Google Sheets, normalizes fields, and runs VerifiEmail checks. Result: 820 emails kept and appended to CleanSubscribers, 360 rows removed from the source sheet, and 20 flagged as tagged for special handling. JSON summary returned with counts and status for auditing. Estimated time: around 3 minutes.

The agent leverages VerifiEmail to detect disposable domains and risky provider data. It uses MX checks and domain reputation signals to assess deliverability. If an email is flagged as disposable or risky, it is classified as remove. The decision is logged in the JSON summary for audit trails. You can adjust tolerance rules in the Classify step if needed.

Yes. You can configure which Google Sheets and which worksheets to target, and you can point the webhook to run for different batch requests. Each run processes its own dataset and updates its own CleanSubscribers sheet. The agent maintains isolation between sheets to avoid cross-contamination of data. It supports batch processing for scheduled cleanups and on-demand runs.

The agent performs normalization first, which standardizes formats and trims whitespace. It then deduplicates based on the normalized email field before deciding keep/remove/tag. Deduplicated, valid emails are appended to CleanSubscribers, while duplicates found in the source can be removed if flagged. You can enable or disable deduplication rules in the configuration. This ensures you don’t send to the same address twice.

Data security is driven by Google Sheets permissions and VerifiEmail API security practices. Access is limited to configured credentials (Sheets read/delete/append and VerifiEmail API key). All processing happens within the authenticated Google account context. Logs include only non-sensitive metadata for auditing. If you require additional encryption in transit, you can route through a secure gateway in your environment.

Processing time scales with list size and network latency to VerifiEmail. For typical batches (a few thousand rows), expect a few minutes per run. The webhook returns progress in the JSON summary, and you can trigger multiple batches sequentially or on a schedule. If your sheet is extremely large, consider chunking the data into smaller batches for responsive processing.

Yes. You can trigger recurring cleanups via your workflow or automation platform by sending periodic webhook requests. The agent will fetch the latest subscriber data, apply normalization and verification, and update CleanSubscribers accordingly. You can set cadence (e.g., weekly) to maintain ongoing list quality. Auditing is preserved in the JSON summaries produced by each run.

Deleted invalid emails are removed from the source sheet as part of cleanup; you should have a backup or version history in Sheets to recover data if needed. The JSON summary includes the actions taken for each row, so you can identify what was deleted, kept, or tagged. If rollback is required, restore from the sheet version history and re-run the cleaning with adjusted rules. For safety, you can temporarily disable deletion while validating the rules on a test subset.
