PHP

Overview

Mailtrap can be integrated with PHP apps and projects for email sending.

Email API/SMTP for PHP

SDK integration

The Mailtrap PHP SDK is a modern, type-safe library for sending transactional and bulk emails from PHP applications. The SDK supports:

Transactional email sending
Batch email sending
Dedicated Laravel and Symfony bridges
Template management
Contact management
Sandbox testing
Account management

Additionally, you can watch the course released by Symfony Casts for a step-by-step integration walkthrough.

Installation

Install the SDK using Composer:

Composer

composer require railsware/mailtrap-php

Minimal Example

Here's a minimal example to send your first email:

send_email.php

<?php

use Mailtrap\Helper\ResponseHelper;
use Mailtrap\MailtrapClient;
use Mailtrap\Mime\MailtrapEmail;
use Symfony\Component\Mime\Address;

require __DIR__ . '/vendor/autoload.php';

$mailtrap = MailtrapClient::initSendingEmails(
    apiKey: getenv('MAILTRAP_API_KEY') // your API key here https://mailtrap.io/api-tokens
);

$email = (new MailtrapEmail())
    ->from(new Address('[email protected]'))
    ->to(new Address('[email protected]'))
    ->subject('Hello from Mailtrap PHP')
    ->text('Plain text body');

$response = $mailtrap->send($email);

// Access response body as array (helper optional)
var_dump(ResponseHelper::toArray($response));

Get your API token from your Mailtrap account under Settings → API Tokens.

SMTP integration

To integrate SMTP with your PHP app, navigate to the Integrations tab, choose the desired PHP framework, and copy-paste the credentials or ready-made code snippets.

SMTP integration is compatible with any PHP framework or library that sends emails via SMTP.

RESTful API integration

To integrate Mailtrap using RESTful API, use the configuration available among Code samples under the API section.

API integration can be used with any PHP framework or library that supports HTTP requests. For more details, refer to the API documentation.
