Resend for Laravel

Resend for Laravel is the official SDK that integrates the Resend email API with Laravel and Symfony Mailer. It registers a Resend mail transport so your existing Mail facade, Mailables, and notifications send through Resend, and it exposes a Resend facade for direct access to the full API (emails, domains, contacts, audiences, and more) via the underlying resend-php client.

Beyond sending, the package wires up Resend’s webhooks to native Laravel events: a signed webhook controller verifies incoming payloads and dispatches typed events such as EmailDelivered, EmailBounced, EmailOpened, EmailClicked, and contact/domain lifecycle events. This lets you react to delivery and engagement signals with ordinary Laravel event listeners.

What You Get

• A Resend mail transport so Mail, Mailables, and notifications send via Resend
• A Resend facade wrapping the resend-php client for emails, domains, contacts, and audiences
• A signed webhook controller and middleware that verifies incoming Resend webhooks
• Typed Laravel events for delivery, opens, clicks, bounces, complaints, and lifecycle changes
• Standard Laravel config and service-provider auto-registration

Common Use Cases

• Sending transactional email through Resend using Laravel’s existing Mail API
• Managing domains, contacts, and audiences programmatically via the Resend facade
• Reacting to delivery and engagement webhooks with Laravel event listeners

Under The Hood

Architecture

ResendServiceProvider registers three things: a Resend transport via ResendTransportFactory (extending Symfony Mailer so Laravel’s Mail layer can send through Resend), a Resend facade backed by the resend-php client for direct API calls, and optional webhook routes. Inbound webhooks hit a WebhookController guarded by VerifyWebhookSignature middleware; after verification it maps each Resend event type to a dedicated Laravel event class under Events/ (EmailSent, EmailDelivered, EmailBounced, EmailOpened, EmailClicked, EmailComplained, plus contact and domain lifecycle events). An ApiKeyIsMissing exception guards misconfiguration.

Tech Stack

PHP 8.1+, depending on illuminate/http and illuminate/support (Laravel 10 through 13), symfony/mailer for the transport, and resend/resend-php as the underlying API client. It autoloads via PSR-4 under Resend\Laravel and auto-discovers its service provider.

Code Quality

The package is cleanly organized into Transport, Facades, Events, and Http (controller + middleware) namespaces, each class small and single-purpose. It ships a Pest test suite covering the facade, transport, HTTP routes, and service provider, consistent with an officially maintained vendor SDK.

API Design

Developer experience is strong: once the API key is configured, existing Laravel mail code works unchanged, and the Resend facade mirrors the resend-php API for everything else. Reacting to delivery events is as simple as listening for the provided event classes, keeping the learning curve low for Laravel developers.
