I built this for signup and contact forms that get mistyped or disposable email addresses.

It checks the format, catches common domain typos, detects disposable providers, and verifies that the domain can receive email.

composer require trueform/trueform

$result = (new Trueform\Client())
    ->validations
    ->create('user@example.com');

$result->isDeliverable();
$result->isDisposable();

It also includes PSR-18 support and Laravel validation rules. No API key required.

• packagist: https://packagist.org/packages/trueform/trueform

I also created a guide on how to integrate it in your app: https://trueform.cloud/docs/php/

If you want to validate email addresses in n8n before passing them to the next step, I built a free, open-source community node:

• GitHub
• npm

It uses the free Trueform validation API to check email format, disposable providers, mail routing, and common domain typos. No API key is required, and requests typically complete in around 50 ms.

I’d love to hear your feedback. What workflows or additional operations would make this node more useful for you?

Hi all,

I see a lot of posts here on how to validate if email exists before losing time doing outreach. I dug into a rabbit hole and finally come up with a service. It is free, I just want to get back at the comunity

Let me know what do you think about it, and if there are changes you would need for your use case :)
