Subscribe, unsubscribe, tag and update your app's records in an email-marketing audience, right from your Filament panel. Ships with drivers for Mailchimp and Brevo, queues bulk syncs, shows each record's subscription status, and puts basic list and campaign stats on your dashboard. It works with Filament 4 and 5.

#What it does

• Record actions: Subscribe, Sync details (fields and tags), Edit tags and Unsubscribe, on any resource whose model is a subscriber: users, customers, leads, members.
• Bulk actions: subscribe, sync or unsubscribe the selected records. They are queued in chunks, so a thousand records never block a request or hit a rate limit head-on.
• Status column and entry: Subscribed, Pending confirmation, Unsubscribed, Cleaned (bounced), Archived in provider or Not subscribed, read from a local status table (no API call per row); "Not synced" until the record's first sync. Cleaned and Archived are Mailchimp states. A red icon marks a record whose last sync failed; hover it for the reason.
• Dashboard widgets: members, unsubscribes, open and click rates, and the latest sent campaigns with their open and click rates. Cached for five minutes. With Mailchimp the rates are the audience's own averages; with Brevo they average the last campaigns sent to the list, and "Unsubscribed" counts the list's blocklisted contacts.
• Consent first: someone the provider reports as unsubscribed (Mailchimp also: cleaned or archived; Brevo: blocklisted or unsubscribed from the list) is never subscribed again from your panel. An unsubscribe made here is recorded and blocks that address in this panel until the provider itself reports the person subscribed again (they rejoined through its own signup form). See Consent and GDPR.
• Drivers: Mailchimp (audiences, merge fields, tags, double opt-in) and Brevo (lists, attributes). The driver contract is ready for more (MailerLite, Kit, your own): see Adding a provider.

It does not send email, build campaigns or sync anything from the provider back into your models.

#Requirements

• PHP 8.2+ (8.3+ for Filament 5 or Laravel 13)
• Laravel 12 or 13
• Filament 4 or 5
• A queue worker for bulk actions (any queue connection; sync works for small lists)
• An API key for your provider: a Mailchimp API key, or a Brevo API v3 key

#Installation

composer require amjadiqbal/filament-audience-sync
php artisan vendor:publish --tag=filament-audience-sync-migrations
php artisan migrate

Add your key and list to .env, then find the list id with the command:

AUDIENCE_SYNC_DRIVER=mailchimp

MAILCHIMP_API_KEY=your-key-us21
MAILCHIMP_LIST_ID=your-audience-id

# or
# AUDIENCE_SYNC_DRIVER=brevo
# BREVO_API_KEY=xkeysib-...
# BREVO_LIST_ID=7

php artisan audience-sync:lists

Make your model a subscriber. The trait sends the email attribute, splits name into first and last name, and adds the relation the status column reads:

use AmjadIqbal\FilamentAudienceSync\Concerns\SyncsWithAudience;
use AmjadIqbal\FilamentAudienceSync\Contracts\Subscribable;

class User extends Authenticatable implements Subscribable
{
    use SyncsWithAudience;

    // Optional: send more fields and tags.
    public function audienceFields(): array
    {
        return ['first_name' => $this->first_name, 'last_name' => $this->last_name, 'COMPANY' => $this->company];
    }

    public function audienceTags(): array
    {
        return $this->is_customer ? ['customer'] : [];
    }
}

Register the plugin and add the column and actions to your resource:

use AmjadIqbal\FilamentAudienceSync\AudienceSyncPlugin;

$panel->plugin(AudienceSyncPlugin::make());

use AmjadIqbal\FilamentAudienceSync\Actions\AudienceActions;
use AmjadIqbal\FilamentAudienceSync\Tables\AudienceStatusColumn;

public static function table(Table $table): Table
{
    return $table
        ->columns([
            TextColumn::make('name'),
            TextColumn::make('email'),
            AudienceStatusColumn::make(),
        ])
        ->recordActions([AudienceActions::group()])
        ->toolbarActions([AudienceActions::bulkGroup()]);
}

On a view or edit page, use the single actions and the status entry:

use AmjadIqbal\FilamentAudienceSync\Infolists\AudienceStatusEntry;

protected function getHeaderActions(): array
{
    return [
        AudienceActions::subscribe(),
        AudienceActions::update(),
        AudienceActions::tags(),       // hidden for drivers without tags (Brevo; audienceTags() is not sent there either)
        AudienceActions::unsubscribe(),
    ];
}

// In the resource's infolist:
AudienceStatusEntry::make(),

Every action takes an optional driver name (AudienceActions::subscribe('brevo')) to target a provider other than the default.

#Field mapping

Your model returns neutral keys; each driver maps them in config/audience-sync.php (php artisan vendor:publish --tag=filament-audience-sync-config):

Any other key is sent unchanged, so you can return provider field names (COMPANY) directly. Empty values are not sent. Mailchimp rejects merge fields that do not exist in the audience; the error is shown on the record.

#How each operation behaves

From code, the same rules apply through the facade:

use AmjadIqbal\FilamentAudienceSync\Facades\AudienceSync;

AudienceSync::subscribe($user);                 // SyncResult: outcome + status
AudienceSync::update($user, 'brevo');
AudienceSync::unsubscribe($user);
AudienceSync::queue(User::whereNotNull('email_verified_at')->get(), 'subscribe');

#Rate limits and queues

A 429 or 5xx answer, or a dropped connection, is retried up to three times, after the provider's Retry-After or rate-limit reset header when it sends one (seconds, an HTTP date or a Unix timestamp), else after 0.5 s, 1 s, 2 s. One call never sleeps more than max_wait_seconds (20) in total, in a web request or a queued job. A queued chunk that is still rate limited is released for the provider's wait (at least 30 s, at most an hour) and runs again, up to six tries; other failures retry after 30 s to 10 minutes. Records are processed one by one, so each operation is safe to repeat. Brevo cannot filter campaigns by list, so the campaigns widget reads the account's latest 100 sent campaigns and keeps those sent to your list. Tune http, queue.chunk, queue.connection and queue.name in the config.

#Who can use it

With no rule set, anyone who can reach the panel can use the actions and see the widgets. Define a gate to restrict it, or pass a closure:

Gate::define('manageAudience', fn (User $user, string $ability, ?Model $record) => $user->isAdmin());

AudienceSyncPlugin::make()
    ->authorizeUsing(fn (string $ability, ?Model $record, ?User $user) => $user?->can('marketing'))
    ->dashboardWidgets(false); // keep the stats widgets off the dashboard

Abilities: subscribe, unsubscribe, update, tag, stats.

#API keys

Keys are read from your .env through the config only. They are never stored in the database, shown in the panel or written to logs, and every provider error message is cleaned of anything that looks like a key before it is shown or saved on the record. Use a key with the smallest access the provider offers.

#Consent and GDPR

You are the data controller. This plugin is a tool for sending your data to a processor of your choice; it does not collect consent for you. Before you subscribe anyone:

• Have a lawful basis (usually freely given, specific consent) and keep a record of it in your app. Bulk subscribing every user is rarely lawful in the EU/UK.
• Prefer Mailchimp's double opt-in (MAILCHIMP_DOUBLE_OPT_IN=true): the provider then sends the confirmation and keeps the proof.
• Respect unsubscribes. The plugin will not subscribe anyone the provider reports as unsubscribed (on Mailchimp also cleaned or archived; on Brevo blocklisted or unsubscribed from the list), or who was unsubscribed from your panel. A person who changes their mind can rejoin through the provider's own signup form; the next Sync details then shows them as subscribed and lifts the local block.
• Send only the fields you need, list your provider in your privacy notice, and have a data processing agreement with it.
• On an erasure request, delete the contact in the provider too (this plugin does not delete contacts) and delete the record's rows in audience_sync_members.

This is not legal advice.

#Adding a provider

A driver implements AmjadIqbal\FilamentAudienceSync\Contracts\AudienceDriver. Extend Drivers\HttpDriver to get authentication, retries, backoff and key redaction for free, then register it:

use AmjadIqbal\FilamentAudienceSync\Facades\AudienceSync;

// config/audience-sync.php: 'drivers' => ['mailerlite' => ['api_key' => env('MAILERLITE_API_KEY'), 'list' => env('MAILERLITE_GROUP_ID')]]
AudienceSync::extend('mailerlite', fn () => new MailerLiteDriver('mailerlite', config('audience-sync.drivers.mailerlite')));

The consent rules and status storage live in the manager, so every driver gets them.

#Testing

composer test

The tests use recorded provider responses (tests/Fixtures/responses) through Laravel's HTTP fake; nothing calls Mailchimp or Brevo. scripts/ci-local.sh runs Pint, PHPStan and Pest on PHP 8.2 to 8.5 with Laravel 12 and 13 and Filament 4 and 5.

#Pro (planned)

A paid Pro version is planned: two-way sync through provider webhooks, audience segments from Filament table filters, automations on model events, re-consent flows, scheduled full syncs, and more providers. The free version stays free.
