How to validate emails and phone numbers in n8n

This video explains how to take advantage of the Email Verification community node within n8n, a workflow automation tool that allows you to connect applications and APIs without over-coding.

What is n8n?

N8N is a visual process orchestrator. Through “nodes” you can chain actions: from receiving data in a form to validating it, transforming it and sending it to other applications. Its main advantage is that it allows third-party services to be integrated with great flexibility.

What are community nodes?

In addition to the official nodes that come pre-installed on n8n, the community develops additional nodes that expand their capabilities. These nodes are installed separately and allow very specific services to be integrated. The Verify Emails node is one of them.

Why use the Verify Emails node?

The Verify Email node helps improve the quality of your data automatically. By validating contact information, you avoid problems such as:

• Emails that bounce back because they don’t exist.

• Invalid or inactive phones.

• Incorrect mailing addresses.

• Misspelled names and surnames.

This translates into fewer errors in your campaigns, higher delivery rate, and more trust in your database.

Data that allows validation

The node centralizes several services into one:

• Email verification

• Phone Verification

• Postal address validation

• Correction and validation of names and surnames

Steps to use the node

1. Install the node
   From your n8n installation add the @verificaremails/n8n-nodes-verificaremails. This is done in the community node directory and requires restarting n8n for it to become available.

2. Configuring the node on n8n
   Once inside your workflow, add the Verify emails node and select what type of data you want to validate: email, phone, address or name.

3. Create APIs in the Email Verification platform
   Go into Verificaremails.com, generate your API key, and copy that token inside the n8n node. That will be your credential so that the node can connect to the service.

   Interpreting the results
   The node returns a report in JSON with the most relevant fields:

   • For emails: whether the email is valid or not, and the reason in case of error.

   • For phones: If active, line type, and country.

   • For addresses: if the address exists and is deliverable.

   • For names: if they are spelled correctly and normalized.

     With this information, you can automatically decide what to do in your flow: save only valid contacts, ask the user for corrections, or filter data according to quality criteria.

   🔑 In short: this community node allows you to centralize the verification of emails, phones, addresses and names directly within n8n in a single point. With just a few setup steps, you can improve the quality of your data and automate tasks that previously required manual checks.
