What This Workflow Does

Collecting email addresses through Google Forms is common for lead generation, event registrations, newsletter sign-ups, and customer feedback. However, a significant portion of submissions can contain fake, disposable, or invalid email addresses. These bad entries pollute your database, waste marketing resources, and can harm your sender reputation if used for email campaigns.

This automation solves that problem instantly. Every time a new response is submitted to your Google Form, the workflow automatically triggers. It sends the submitted email address to Email List Verify for real-time validation. If the email is verified as legitimate (not disposable, syntactically correct, and from a real domain), the entire form response data is added as a new row in your designated Google Sheet. Invalid emails are filtered out, keeping your spreadsheet clean and reliable from the moment data arrives.

The result is a seamless, trustworthy data collection pipeline. You no longer need to manually check emails or clean lists later. Your team can confidently act on new leads, send follow-ups, or analyze trends because every entry in your sheet has passed a quality check. This turns Google Forms from a simple collection tool into a powerful, validated lead source.

How It Works

The workflow operates in a clear, automated sequence. Here’s a step-by-step breakdown of the process.

Step 1: Trigger on New Form Submission

The Make.com scenario watches your Google Form for new responses. As soon as someone submits the form, the workflow is activated and receives all the submitted data, including the email address, name, answers, and timestamp.

Step 2: Validate the Email Address

The workflow passes the submitted email address to the Email List Verify module. This service checks the email against multiple criteria: whether it's from a disposable email service (like temporary mail providers), if the syntax is valid, if the domain exists, and if it's known to be a spam trap or fraudulent address. The verification returns a result (typically "valid" or "invalid").

Pro tip: You can configure the workflow to only proceed if the email status is "valid." This means invalid emails stop here, preventing any further actions and keeping your main sheet clean.

Step 3: Route Valid Data to Google Sheets

If the email is verified as valid, the workflow proceeds to the next module: Google Sheets. It maps the data from the form response (like name, email, answers) to corresponding columns in your predefined spreadsheet. A new row is added instantly, creating a live, updated database of verified contacts.

Step 4: Optional Handling for Invalid Emails

You can extend the workflow to handle invalid emails intelligently. For example, you could route them to a separate "Review" sheet, send a notification to your team, or even trigger a follow-up message to the submitter asking for a correct email. This flexibility allows you to monitor submission quality without corrupting your primary list.

Who This Is For

This automation is ideal for any business or individual that relies on email data collected through forms.

Marketing & Lead Generation Teams: Collecting webinar registrations, ebook downloads, or newsletter sign-ups. Ensuring every lead is a real person with a reachable email improves conversion rates and campaign ROI.

Event Organizers & Educators: Managing registrations for workshops, courses, or conferences. Validated emails guarantee communication reaches attendees and reduces administrative follow-up on incorrect details.

Customer Support & Feedback Collectors: Gathering customer satisfaction surveys or feedback forms. Valid emails ensure you can follow up on issues or thank respondents, enhancing customer relationship management.

Small Business Owners & Freelancers: Using Google Forms for client inquiries, project applications, or contact forms on websites. Automating validation saves time and ensures you only engage with serious, legitimate prospects.

Researchers & Data Analysts: Conducting surveys or studies where participant contact information is required for longitudinal communication. Data integrity is crucial for research validity.

What You'll Need

To set up this workflow, you'll need the following accounts and assets ready.

  1. A Google Forms form that collects email addresses as part of its responses.
  2. A Google Sheets spreadsheet where you want the validated data to be stored. Prepare the column headers to match your form fields.
  3. A Make.com account (free tier works for this template).
  4. An Email List Verify account or API key. This service provides the email validation check.
  5. Basic understanding of how to connect apps in Make.com (the template provides a guided setup).

Key Benefits

Immediate Data Quality Assurance: Every email is validated at the point of entry. Your database or contact list remains clean from the start, eliminating the need for periodic, manual data cleansing projects that consume hours of team time.

Increased Operational Efficiency: Automation removes the manual step of checking each submission. Your team can focus on engaging with verified leads rather than vetting data. This speeds up follow-up processes and improves response rates.

Protection of Marketing Resources: Sending emails to invalid or disposable addresses wastes budget and can damage your sender score with email providers. This workflow ensures your marketing emails only go to legitimate addresses, protecting your investment and reputation.

Enhanced Lead Confidence: Knowing that every contact in your sheet is verified allows your sales or marketing team to act with confidence. There's no hesitation about whether an email is real, which increases the aggressiveness and effectiveness of outreach campaigns.

Scalable Foundation: This workflow can be extended. Once validated data is in Google Sheets, you can trigger further automations—like adding contacts to a CRM, sending welcome emails, or creating analytics reports—creating a fully automated lead management system.

Frequently Asked Questions

Common questions about email validation automation and integration

Email validation ensures the data you collect is reliable and actionable. Without it, you risk filling your database with fake, disposable, or invalid email addresses, which wastes marketing resources, skews analytics, and damages communication efforts. Automated validation filters out bad data before it enters your systems, saving time and improving campaign effectiveness.

For example, a webinar registration form without validation could end up with 30% fake emails, meaning your follow-up emails bounce and your attendance metrics are inaccurate. Validation turns raw submissions into a trustworthy lead list.

Email List Verify checks for disposable email addresses (like temporary mail services), invalid syntax, spam traps, and known fraudulent domains. It helps identify emails that are likely to bounce or be unresponsive, protecting your sender reputation and ensuring you only communicate with legitimate, interested contacts.

The service uses real-time databases and algorithms to assess email quality, giving you a simple "valid" or "invalid" result that you can use to automate data routing in your workflows.

Manual email validation is tedious and error-prone. Automation instantly checks each submission as it arrives, eliminating hours spent cleaning lists later. It ensures real-time data quality, allowing teams to act on leads immediately without second-guessing contact information. This speeds up follow-up processes and improves overall operational efficiency.

Consider a team that manually reviews 500 form submissions a month. Automation can save them 10-15 hours of work monthly, freeing them for higher-value tasks like engaging with verified leads.

Yes, the core principle works for any form or data source. Make.com can connect to platforms like Typeform, SurveyMonkey, webhook submissions, or CRM entries. The workflow triggers on new data, validates the email via Email List Verify, and then routes the verified information to your preferred destination, such as Google Sheets, a CRM, or an email marketing tool.

The flexibility of automation platforms means you can adapt this validation step to fit your existing data collection channels without rebuilding entire processes.

The workflow can be configured to handle invalid emails appropriately. Common actions include sending the submission to a separate 'invalid' sheet for review, triggering an alert to the team, or simply not adding it to the main database. This keeps your primary contact list clean while allowing you to monitor submission trends and potential issues.

You can also set up a follow-up email asking the submitter to provide a correct address, turning a failed validation into an opportunity for correction rather than a total loss.

Direct automation creates a live, organized database without manual copying. It reduces human error, ensures data is instantly available for analysis or sharing, and maintains a single, updated source of truth. Teams can set up dashboards, reports, or alerts based on the sheet data, turning raw submissions into actionable business intelligence.

When combined with email validation, this integration ensures that the live data is also high-quality, making every chart, report, or notification based on the sheet more reliable and valuable.

Start by defining clear rules for valid vs. invalid emails. Test the workflow with sample data before full deployment. Regularly review the validation results to adjust thresholds if needed. Ensure your Google Sheet has clear columns for status (valid/invalid) and timestamp. Consider adding a secondary notification for team members when high-value leads are validated and added.

  • Test with both valid and invalid sample emails.
  • Label columns in your sheet for easy analysis.
  • Monitor the "invalid" stream for patterns.
