LeadMail SDK for Laravel

Laravel package for sending emails and verifying email addresses through the leadMail service.

Requirements

• PHP 8.2+
• Laravel 11, 12, or 13

Installation

composer require leadm/leadmail

Add these to your .env:

LEADMAIL_URL=https://mail.leadmagnet.dev
LEADMAIL_TOKEN=lm_your_api_token_here
MAIL_MAILER=leadmail

Then run the installer:

php artisan leadmail:install

That's the whole setup. The command publishes the config, registers this app's failure-webhook URL with the service, and writes the generated LEADMAIL_WEBHOOK_SECRET into your .env — no secret to copy by hand. It runs without prompts, so it's safe in CI/Ploi deploy hooks. See Receiving Failure Webhooks for what it wires up.

If you only need sending/verification and not webhooks, you can skip the installer and just publish the config with php artisan vendor:publish --tag=leadmail-config.

Configuration

Everything is configured by environment variables; the published config/leadmail.php reads from them. All of these are optional and have sensible defaults:

LEADMAIL_TIMEOUT=30
LEADMAIL_VERIFY_SSL=true
LEADMAIL_AUTO_TENANT=true

# Retry transient failures (connection errors, 429/5xx) on idempotent calls.
# Sends are never retried automatically, to avoid duplicate emails.
LEADMAIL_RETRIES=2
LEADMAIL_RETRY_DELAY_MS=200

# Set automatically by `php artisan leadmail:install` — you normally don't edit
# these by hand. The secret signs incoming webhooks; the route is where they land.
LEADMAIL_WEBHOOK_SECRET=whsec_...
LEADMAIL_WEBHOOK_ROUTE=/webhooks/leadmail

Usage

Send Emails via Mail Driver

Set leadmail as your mail driver in .env:

MAIL_MAILER=leadmail

Then use Laravel's Mail facade as usual:

Mail::to('user@example.com')->send(new WelcomeMail());

Send Emails via API

LeadMail::sendEmail([
    'from' => ['email' => 'hello@yourdomain.com', 'name' => 'Your App'],
    'to' => [['email' => 'user@example.com', 'name' => 'User']],
    'subject' => 'Welcome!',
    'html_body' => '<h1>Welcome to our app</h1>',
]);

Verify Email Addresses

$result = LeadMail::verifyEmail('user@example.com');

if ($result['data']['valid']) {
    // Email is deliverable
}

Validation Rule

Use the leadmail_verify rule in your form requests:

public function rules(): array
{
    return [
        'email' => ['required', 'email', 'leadmail_verify'],
    ];
}

Get Allowed Sender Domains

$domains = LeadMail::getDomains();
// ['yourdomain.com', 'anotherdomain.com']

Error Handling

Every API failure is raised as a typed exception so you can handle it reliably from the client side. LeadMail::verifyEmail() is the exception — it fails open (returns status: "unknown") so a verification outage never blocks sign-ups.

Exception	When
LeadM\LeadMail\Exceptions\LeadMailRequestException	The service returned an error response (4xx/5xx).
LeadM\LeadMail\Exceptions\LeadMailConnectionException	The service could not be reached (DNS/connection/timeout).
LeadM\LeadMail\Exceptions\LeadMailException	Base class for both of the above; catch this to handle any failure.

use LeadM\LeadMail\Exceptions\LeadMailRequestException;
use LeadM\LeadMail\Exceptions\LeadMailConnectionException;

try {
    LeadMail::sendEmail([...]);
} catch (LeadMailRequestException $e) {
    $e->statusCode();        // e.g. 422, 502
    $e->errorCode();         // e.g. "TRANSPORT_ERROR" (from the API envelope)
    $e->logId();             // the email log id, when available
    $e->validationErrors();  // ['from.email' => ['...']] on a 422
    $e->isValidationError();
    $e->isAuthenticationError();
} catch (LeadMailConnectionException $e) {
    // Service unreachable — safe to queue and retry yourself.
}

Idempotent calls (getDomains, verifyEmail) automatically retry transient failures (connection errors and 429/5xx) with exponential backoff. Sends are never retried automatically — a retry after a dropped connection could deliver the same email twice. Retry sends yourself via a queued job if you need to.

Receiving Failure Webhooks

leadMail POSTs a signed email.failed webhook to your app when a send ultimately fails. This works out of the box — no route or config required.

Setup: one command

With LEADMAIL_TOKEN set in your .env, run:

php artisan leadmail:install

It runs without prompts (safe for Ploi/CI) and:

1. publishes the config,
2. registers your webhook URL with the leadMail service over the API (authenticated by your token), derived from APP_URL + the configured webhook route,
3. writes the generated LEADMAIL_WEBHOOK_SECRET into your .env.

That's it. The SDK auto-registers the receiving route (/webhooks/leadmail by default), which verifies the HMAC signature and logs every failure by default. Nothing else to wire up.

Options:

• --url=https://your-app.com/custom/path — override the derived URL.
• --rotate — generate and store a fresh signing secret.

The secret is generated server-side and returned only once, at registration.

Custom handling

To do more than log (e.g. flag a contact, alert a channel), listen for the LeadMailWebhookReceived event:

use LeadM\LeadMail\Events\LeadMailWebhookReceived;

Event::listen(function (LeadMailWebhookReceived $received) {
    $event = $received->event;

    if ($event->isFailure()) {
        // $event->logId, $event->errorCode, $event->errorMessage,
        // $event->from, $event->to, $event->subject, $event->metadata
    }
});

Customising or replacing the route

• LEADMAIL_WEBHOOK_ROUTE — change the path (keep it in sync with the registered URL via leadmail:install).
• Set leadmail.webhook_route to null to disable auto-registration and handle the request yourself with LeadMailWebhook::parse($request) (verifies the signature against the raw body, throws InvalidWebhookSignatureException on mismatch; verify() returns a boolean instead).

Multi-Tenancy

If your app uses stancl/tenancy, the SDK automatically includes the current tenant ID in API requests via the X-Tenant-Id header. Disable this with:

LEADMAIL_AUTO_TENANT=false
