Clearout - An Official Email Verification and Email Finding Node.js Library

The Clearout node library is a wrapper of the Clearout REST API and allows developers to write applications in server-side JavaScript to perform real-time, bulk email verification and discovery. This programmatic interface will allow you to easily integrate into your use cases such as

• Avoid capturing bad email addresses in your forms, chats, or anywhere else where email is accepted.
• Bulk email verification to remove invalid, dead and fake emails from your email lists
• Email finder to build pre-verified & accurate B2B leads for cold outreach

Clearout infrastructure has been designed to retain high throughput, security and precision accuracy. Bulk email verification or email finder support lists of any size, as long as credits are available in account

Documentation

See the Clearout API docs to know RESTFul endpoints

Requirements

Node >= 10 or higher.

Installation

Install the package with:

npm install @clearoutio/clearout --save

Usage

The package needs to be initialized with your Clearout's server app API token, which is available in the Clearout Apps Dashboard. If you don't find server app, please create one and copy the API token

Using as commonJS module with Promise:

const clearout = require('@clearoutio/clearout')('replace-with-your-api-token', { timeout: 5000 })

try {
  clearout.emailVerifier.verify({ email: 'elon.musk@tesla.com' })
    .then(result => console.log(`Email ${result.email_address} status is ${result.status}, Is it safe to send? ${result.safe_to_send}`))
    .catch(error => console.error(error));
}
catch (error) {
  console.error(error)
}

Or using as ES modules with async/await:

import Clearout from '@clearoutio/clearout';

(async () => {
  try {
    const clearout = new Clearout('replace-with-your-api-token', { timeout: 5000 });
    const result = await clearout.emailVerifier.verify({ email: 'elon.musk@tesla.com' });
    console.log(`Email ${result.email_address} status is ${result.status}, Is it safe to send? ${result.safe_to_send}`);
  } catch (error) {
    console.error(error)
  }
})();

Configuration

Initialize with config object

All service level settings for the Clearout package can be initialized, but they can be overridden when invoking the specific service methods.

import Clearout from '@clearoutio/clearout';
const clearout = new Clearout("replace-with-your-api-token", {timeout: 5000, ignore_result: true, ignore_duplicate_file: 'true'});

Option	Default	Description
token	null	Clearout server app API token
timeout	130,000 ms (Email Verifier) 30,000 ms (Email Finder)	Maximum time each request can take in milliseconds
ignore_result	false	Ignore the result file, even if it's not downloaded. Used when invoking list removal
ignore_duplicate_file	'false'	Whether to allow duplicate file upload based on file name and size.

Error Handling

All service methods return promise and throw an exception in case if the response status is failed, hence the recommended approach would be to call service method within a try...catch block

const clearout = require('@clearoutio/clearout')('replace-with-your-api-token', {timeout: 30000})

async function findEmail(name, domain) {
  try {
    console.log('Finding email, please wait...')
    const result = await clearout.emailFinder.find({ name, domain});
    console.log(`Email found ${result.emails[0].email_address} with confidence score ${result.confidence_score}`);
  } catch (error) {
    console.error('Errored:', error.message)
  }
}

findEmail('elon musk', 'tesla.com')
