README

Official Volpa Mail SDK and Mail Transport for Laravel. Send transactional emails through the Volpa Mail API using Laravel's native Mail facade or the SDK directly — with typed DTOs, retries, and rich error handling.

What this package is: the client SDK that your Laravel apps install to send mail through Volpa Mail. It does not contain the Volpa Mail backend (the multi-tenant sending platform).

Installation

composer require samuelterra22/volpa-mail-laravel

The service provider and the VolpaMail facade are auto-discovered — no manual registration needed.

Publish the config (optional, only if you want to tweak defaults):

php artisan vendor:publish --tag=volpa-mail-config

This creates config/volpa-mail.php.

Configuration

Add your credentials to .env:

VOLPA_MAIL_API_KEY=your-tenant-api-key
VOLPA_MAIL_BASE_URL=https://mail.volpa.com.br/v1

All available environment variables:

Env variable	Config key	Default	Description
VOLPA_MAIL_API_KEY	api_key	(none — required)	Tenant API key. Sent in the X-API-Key header on every request. Generated in the Volpa Mail panel under Settings → API Keys.
VOLPA_MAIL_BASE_URL	base_url	https://mail.volpa.com.br/v1	Base endpoint of the REST API. Includes the /v1 version prefix, no trailing slash.
VOLPA_MAIL_TIMEOUT	timeout	10	Per-request timeout, in seconds.
VOLPA_MAIL_RETRY_TIMES	retry.times	2	Retry attempts on network failure or 5xx.
VOLPA_MAIL_RETRY_SLEEP	retry.sleep	200	Wait between retries, in milliseconds.

The API key is mandatory. If it is missing, the SDK throws VolpaMailException::missingApiKey() on the first call — fail fast instead of silently dropping mail.

Quick start

use SamuelTerra\VolpaMail\Facades\VolpaMail;

$sent = VolpaMail::emails()->send([
    'from'    => ['email' => '[e-mail]', 'name' => 'Athelier'],
    'to'      => [['email' => '[e-mail]']],
    'subject' => 'Sua reserva foi confirmada!',
    'html'    => '<h1>Obrigado!</h1>',
]);

echo $sent->id;            // eml_123
echo $sent->status->value; // queued

Using as a Laravel Mailer

Register the mailer in config/mail.php:

'mailers' => [
    // ...
    'volpa-mail' => [
        'transport' => 'volpa-mail',
    ],
],

Make it the default mailer:

MAIL_MAILER=volpa-mail

…or use it on demand for a single message:

use App\Mail\WelcomeMail;
use Illuminate\Support\Facades\Mail;

Mail::mailer('volpa-mail')->to($user->email)->send(new WelcomeMail($user));

All standard Mailable features work as usual — Markdown mailables, attachments, cc/bcc, replyTo, custom headers. The transport converts the Symfony message into a Volpa Mail API call and records the returned email ID as the message ID (setMessageId($sent->id)) so you can correlate it with webhook events on the backend.

Using as a direct SDK

For fine-grained control, templates, and variables, call the SDK directly.

With a friendly array

use SamuelTerra\VolpaMail\Facades\VolpaMail;

$sent = VolpaMail::emails()->send([
    'from'        => ['email' => '[e-mail]', 'name' => 'Volpa'],
    'to'          => [['email' => '[e-mail]', 'name' => 'João']],
    'cc'          => [['email' => '[e-mail]']],
    'subject'     => 'Sua reserva foi confirmada!',
    'html'        => '<h1>Obrigado, João!</h1>',
    'text'        => 'Obrigado, João!',
    'template_id' => 'reservation-confirmation',
    'variables'   => ['name' => 'João', 'date' => '20/06/2026'],
    'tags'        => ['reserva'],
    'headers'     => ['X-Campaign' => 'reservas-junho'],
]);

With a typed DTO

use SamuelTerra\VolpaMail\Data\Address;
use SamuelTerra\VolpaMail\Data\SendEmailData;
use SamuelTerra\VolpaMail\Facades\VolpaMail;

$sent = VolpaMail::emails()->send(new SendEmailData(
    from:    new Address('[e-mail]', 'Volpa'),
    to:      [new Address('[e-mail]', 'João')],
    subject: 'Olá',
    html:    '<p>Conteúdo</p>',
));

Idempotency-Key on send

Pass a unique key as the second argument to send() to enable idempotent delivery. The backend replays the same response for a repeated key (24-hour TTL) instead of sending a duplicate email. On a body mismatch for the same key, the API returns 409 Conflict.

The recommended key format is UUID v7 (time-ordered):

use Illuminate\Support\Str;
use SamuelTerra\VolpaMail\Facades\VolpaMail;

// Primeira tentativa
$sent = VolpaMail::emails()->send([
    'from'    => ['email' => '[e-mail]'],
    'to'      => [['email' => '[e-mail]']],
    'subject' => 'Confirmação de pedido',
    'html'    => '<p>Seu pedido foi confirmado.</p>',
], Str::uuid7());

// Segunda chamada com a mesma chave — sem reenvio, retorna o mesmo $sent

Store the key with the job so retries reuse it safely.

Suppressions

Manage the suppression list (hard bounces, complaints, unsubscribes, etc.):

use SamuelTerra\VolpaMail\Enums\SuppressionReason;
use SamuelTerra\VolpaMail\Facades\VolpaMail;

// Listar supressões (com filtros opcionais)
$suppressions = VolpaMail::suppressions()->list(['reason' => 'hard_bounce']);

// Adicionar uma supressão manualmente
$suppression = VolpaMail::suppressions()->create(
    '[e-mail]',
    SuppressionReason::Manual,
);

// Consultar
$suppression = VolpaMail::suppressions()->get('[e-mail]');

// Remover (permite reenvio para este endereço)
VolpaMail::suppressions()->delete('[e-mail]');

// Importar em lote
VolpaMail::suppressions()->import(
    ['[e-mail]', '[e-mail]'],
    SuppressionReason::HardBounce,
);

SuppressionReason cases: HardBounce, SoftBounceRepeated, Complaint, Unsubscribe, Manual, InvalidAddress.

Contacts & contact lists

use SamuelTerra\VolpaMail\Facades\VolpaMail;

// Contatos
$contacts = VolpaMail::contacts()->list(['status' => 'active']);
$contact  = VolpaMail::contacts()->create([
    'email' => '[e-mail]',
    'name'  => 'João Silva',
]);
$contact  = VolpaMail::contacts()->get($contact->id);

// Listas de contatos
$lists = VolpaMail::contactLists()->list();
$list  = VolpaMail::contactLists()->create(['name' => 'Newsletter Junho']);
$list  = VolpaMail::contactLists()->get($list->id);

// Importar contatos para uma lista
VolpaMail::contactLists()->import($list->id, [
    ['email' => '[e-mail]', 'name' => 'Ana'],
    ['email' => '[e-mail]', 'name' => 'Bruno'],
]);

ContactStatus cases: Active, Unsubscribed, Bounced, Complained.

Broadcasts

use SamuelTerra\VolpaMail\Facades\VolpaMail;

// Criar um broadcast (campanha)
$broadcast = VolpaMail::broadcasts()->create([
    'name'        => 'Promoção Julho',
    'subject'     => 'Aproveite as ofertas de julho!',
    'template_id' => 'promo-julho',
    'list_id'     => $list->id,
]);

// Enviar
$result = VolpaMail::broadcasts()->send($broadcast->id);
// $result = ['id' => '...', 'status' => 'sending', 'total_queued' => 1234]

// Cancelar (enquanto ainda não completou)
$broadcast = VolpaMail::broadcasts()->cancel($broadcast->id);

// Listar e consultar
$all       = VolpaMail::broadcasts()->list();
$broadcast = VolpaMail::broadcasts()->get($broadcast->id);

BroadcastStatus cases: Draft, Scheduled, Sending, Sent, Canceled, Failed. Use $status->isFinal() to check if the broadcast has reached a terminal state.

Webhook verification

The Volpa Mail backend sends events to your endpoint (e.g. delivered, bounced) signed with a custom HMAC-SHA256 scheme.

Signature format — the delivery header is X-VolpaMail-Signature:

t=<unix_timestamp>,v1=<hex_hmac>

The signed string is <unix_timestamp>.<raw_json_body>. The tolerance window defaults to 300 seconds.

Verifying in a controller

use Illuminate\Http\Request;
use SamuelTerra\VolpaMail\Webhooks\WebhookVerifier;

class VolpaWebhookController extends Controller
{
    public function handle(Request $request): \Illuminate\Http\Response
    {
        $secret   = config('services.volpa_mail.webhook_secret');
        $verifier = new WebhookVerifier();

        if (! $verifier->verifyRequest($request, $secret)) {
            abort(401, 'Assinatura inválida.');
        }

        $event = $verifier->parseEvent($request->getContent());
        // $event->type    — ex.: 'email.delivered'
        // $event->created — timestamp ISO 8601
        // $event->data    — array com os detalhes do evento

        // Processar o evento...
        return response('', 200);
    }
}

Or verify raw payload + header string manually:

$ok = $verifier->verify(
    payload:         $rawBody,
    secret:          $secret,
    signatureHeader: $request->header('X-VolpaMail-Signature'),
    tolerance:       300, // segundos (padrão)
);

The event type is also available in the X-VolpaMail-Event header if you need it before parsing the body.

Email payload reference

Fields accepted by send() (array keys / DTO constructor args). Empty optional fields are omitted from the request body.

Field (array)	DTO arg	Type	Required	Notes
from	from	array{email,name?} / Address	✅	Sender.
to	to	list of {email,name?} / Address[]	✅	At least one recipient.
cc	cc	list / Address[]	—	Carbon copy.
bcc	bcc	list / Address[]	—	Blind carbon copy.
reply_to	replyTo	list / Address[]	—	Reply-To addresses.
subject	subject	string	⚠️	Required unless a template_id supplies it.
html	html	string	—	HTML body.
text	text	string	—	Plain-text body.
template_id	templateId	string	—	Template slug or ID on the backend.
variables	variables	array<string,mixed>	—	Template variables.
tags	tags	string[]	—	Tags for filtering/analytics.
headers	headers	array<string,string>	—	Custom X-* headers.
attachments	attachments	Attachment[]	—	See Attachments.

Attachments

Build an attachment from a file on disk (it is read and base64-encoded for you):

use SamuelTerra\VolpaMail\Data\Attachment;
use SamuelTerra\VolpaMail\Facades\VolpaMail;

VolpaMail::emails()->send([
    'from'        => ['email' => '[e-mail]'],
    'to'          => [['email' => '[e-mail]']],
    'subject'     => 'Sua nota fiscal',
    'html'        => '<p>Segue em anexo.</p>',
    'attachments' => [
        Attachment::fromPath(storage_path('app/notas/nf-123.pdf')),
    ],
]);

Or construct it explicitly with already-encoded content:

new Attachment(
    filename:    'nf-123.pdf',
    content:     base64_encode($pdfBytes),
    contentType: 'application/pdf',
);

Checking delivery status

$email = VolpaMail::emails()->get('eml_123');

$email->id;                   // 'eml_123'
$email->status;               // EmailStatus enum
$email->status->value;        // 'delivered'
$email->status->isTerminal(); // true for delivered/bounced/failed/complained/rejected/canceled
$email->from;                 // ?string — sender address
$email->to;                   // list<string> — recipient addresses
$email->subject;              // ?string
$email->messageStream;        // ?string — stream/pool identifier

EmailStatus cases:

Case	Value	Terminal?
Pending	pending	—
Queued	queued	—
Scheduled	scheduled	—
Processing	processing	—
Sent	sent	—
Delivered	delivered	✅
Opened	opened	—
Clicked	clicked	—
Deferred	deferred	—
Bounced	bounced	✅
SoftBounced	soft_bounced	—
Complained	complained	✅
Rejected	rejected	✅
Failed	failed	✅
Canceled	canceled	✅

Error handling

Any non-2xx response (or a missing API key) raises a SamuelTerra\VolpaMail\Exceptions\VolpaMailException:

use SamuelTerra\VolpaMail\Exceptions\VolpaMailException;
use SamuelTerra\VolpaMail\Facades\VolpaMail;

try {
    VolpaMail::emails()->send([/* ... */]);
} catch (VolpaMailException $e) {
    $e->getMessage();   // human-readable message from the API
    $e->status;         // ?int — HTTP status code (e.g. 422)
    $e->errors;         // array<string, mixed> — field => [messages]
    $e->errorCode;      // ?string — machine code, e.g. 'sender_not_found'
    $e->retryAfter;     // ?int — seconds to wait (parsed from Retry-After on 429)
}

The exception parses both error envelopes returned by the backend: {"error":{"code","message"}} and {"message","errors"}. On HTTP 429, check $e->retryAfter before scheduling a retry.

Troubleshooting

Symptom	Likely cause	Fix
VolpaMailException: Missing Volpa Mail API key	VOLPA_MAIL_API_KEY not set (or config cached).	Set the env var, then php artisan config:clear.
401 Unauthorized	Invalid/revoked API key, or key from the wrong tenant.	Re-issue the key in the panel and update .env.
403 Forbidden	IP allowlist on the key, or sender not verified.	Allow your server IP / verify the sender domain in the panel.
422 Unprocessable Entity	Validation failed (e.g. missing subject and template_id).	Inspect $e->errors for the offending fields.
Mail silently not sent via Mail::	volpa-mail mailer not registered in config/mail.php.	Add the mailer block shown above.
Connection timeouts	Network/firewall or low VOLPA_MAIL_TIMEOUT.	Raise the timeout / check egress to mail.volpa.com.br.

Testing & quality

The test suite uses Pest and Orchestra Testbench with Http::fake() — no real network calls are made.

composer test       # Pest test suite
composer analyse    # PHPStan / Larastan level 8
composer format     # Laravel Pint (code style)

Run all three before pushing:

composer test && composer analyse && composer format

Contributing — Conventional Commits & releases

This package is versioned automatically. When you push to main, the CI workflow runs the tests; if they pass, the Release workflow reads the commit messages, computes the next version (SemVer), and publishes the tag + GitHub Release — which syncs Packagist. You never create a tag by hand.

For this to work, commits must follow the Conventional Commits standard:

<type>[optional scope]: <description>

[optional body]

[optional footer]

Types and version impact

Commit type	Example	Version effect
feat:	feat: add ContactResource	minor (1.2.0 → 1.3.0)
fix:	fix: fix retry on 429	patch (1.2.0 → 1.2.1)
perf:	perf: reduce allocation in toArray	patch
BREAKING CHANGE	see below	major (1.2.0 → 2.0.0)
chore: docs: test: ci: style: refactor: build:	—	none (no release)

Since the workflow uses default_bump: false, a push that contains only no-effect commits (e.g. just docs:) does not generate a release — correct SemVer behavior.

Breaking change (major)

Use ! after the type or a BREAKING CHANGE: footer:

feat!: rename VolpaMail::emails()->find() to ->get()

BREAKING CHANGE: the find() method was removed; use get().

Examples

git commit -m "feat: support Idempotency-Key on send()"
git commit -m "fix(transport): propagate reply_to when converting Symfony Email"
git commit -m "docs: document status lookup"   # no release

Before pushing, make sure the gate is green locally:

composer test && composer analyse && composer format
