Kickbox Email Verification Service

Email Verification Library for PHP

Kickbox determines if an email address is not only valid, but associated with a actual user. Uses include:

  • Preventing users from creating accounts on your applications using fake, misspelled, or throw-away email addresses.
  • Reducing bounces by removing old, invalid, and low quality email addresses from your mailing lists.
  • Saving money and projecting your reputation by only sending to real email users.

Getting Started

To begin, hop over to kickbox.io and create a free account. Once you've signed up and logged in, click on API Settings and then click Add API Key. Take note of the generated API Key - you'll need it to setup the client as explained below.

Installation

Make sure you have composer installed.

Add the following to your composer.json

{
    "require": {
        "kickbox/kickbox": "*"
    }
}

Update your dependencies

$ php composer.phar update

This package follows the PSR-0 convention names for its classes, which means you can easily integrate these classes loading in your own autoloader.

Versions

Works with [ 5.4 / 5.5 ]

Usage

<?php

// This file is generated by Composer
require_once 'vendor/autoload.php';

$client   = new Kickbox\Client('Your_API_Key_Here');
$kickbox  = $client->kickbox();

try {
  $response = $kickbox->verify("test@example.com");
}
catch (Exception $e) {
  echo "Code: " . $e->getCode() . " Message: " . $e->getMessage();
}

Options

timeout integer (optional) - Maximum time, in milliseconds, for the API to complete a verification request. Default: 6000.

// Example with options
$response = $kickbox->verify("test@example.com", array('timeout' => 6000));

Response information

A successful API call responds with the following values:

  • result string - The verification result: deliverable, undeliverable, risky, unknown
  • reason string - The reason for the result. Possible reasons are:
    • invalid_email - Specified email is not a valid email address syntax
    • invalid_domain - Domain for email does not exist
    • rejected_email - Email address was rejected by the SMTP server, email address does not exist
    • accepted_email - Email address was accepted by the SMTP server
    • low_quality - Email address has quality issues that may make it a risky or low-value address
    • low_deliverability - Email address appears to be deliverable, but deliverability cannot be guaranteed
    • no_connect - Could not connect to SMTP server
    • timeout - SMTP session timed out
    • invalid_smtp - SMTP server returned an unexpected/invalid response
    • unavailable_smtp - SMTP server was unavailable to process our request
    • unexpected_error - An unexpected error has occurred
  • role true | false - true if the email address is a role address (postmaster@example.com, support@example.com, etc)
  • free true | false - true if the email address uses a free email service like gmail.com or yahoo.com.
  • disposable true | false - true if the email address uses a disposable domain like trashmail.com or mailinator.com.
  • accept_all true | false - true if the email was accepted, but the domain appears to accept all emails addressed to that domain.
  • did_you_mean null | string - Returns a suggested email if a possible spelling error was detected. (bill.lumbergh@gamil.com -> bill.lumbergh@gmail.com)
  • sendex float - A quality score of the provided email address ranging between 0 (no quality) and 1 (perfect quality). More information on the Sendex Score can be found here.
  • email string - Returns a normalized version of the provided email address. (BoB@example.com -> bob@example.com)
  • user string - The user (a.k.a local part) of the provided email address. (bob@example.com -> bob)
  • domain string - The domain of the provided email address. (bob@example.com -> example.com)
  • success true | false - true if the API request was successful (i.e., no authentication or unexpected errors occurred)

An example response would look like:

$response = $kickbox->verify('test@example.com');
var_dump($response);

//Below is an example of what the var_dump($response) looks like:
