README

MailTracker will hook into all outgoing emails from Laravel and inject a tracking code into it. It will also store the rendered email in the database. There is also an interface to view sent emails.

NOTE: If you are using Laravel 9.x you MUST be on version 9.6.0 or higher.

Upgrade from 4.x to 5.x

In 4.x and previous, there was a recipient column in the sent_emails table that stored the RFC standard email format <Name> email@example.com. 5.x has updated to store the name and email separately. The recipient and sender columns have been removed from the sent_emails table migration, but no migration was added to drop those columns. Accessors have been added to retain the model's recipient and sender attributes, so no updates should need to be made to any code that currently uses those unless you are specifically querying the sender or recipient columns.

To retain your existing data afer upgrading, run the artisan command mail-tracker:migrate-recipients. This will convert the existing recipient and sender data into the new format. At this point you may drop the recipient and sender columns.

There is also a new pair of attributes in the sent_emails table: opened_at and clicked_at. Those store the first time the user opened and clicked, respectively. This has been added to the default tracker index page. You are welcome to add it into yours, or use those values as you see fit.

Upgrade from 3.x to 4.x

There are no breaking changes from 3.x to 4.x with the exception that 4.x is for Laravel 7+ only.

Upgrade from 2.x to 3.x

There was a breaking change with the update to version 3.0, specifically regarding the events that are fired. If you are listening for the PermanentBouncedMessageEvent to catch all undeliverables, there are now two separate events: PermanentBouncedMessageEvent will be fired only on permanent bounces, and a new event ComplaintMessageEvent will be fired on complaints. There is also an new event EmailDeliveredEvent that is fired for each successful delivery event. For information about setting up the SES/SNS environment to receive notifications regarding these events, see the documentation below.

Upgrade from 2.0 or earlier

First, upgrade to version 2.2 by running:

composer require jdavidbakr/mail-tracker ~2.2

If you are updating from an earlier version, you will need to update the config file and run the new migrations. For best results, make a backup copy of config/mail-tracker.php and the views in resources/views/vendor/emailTrackingViews (if they exists) to restore any values you have customized, then delete that file and run

php artisan vendor:publish

php artisan migrate

Also note that the migration for the sent_emails_url_clicked table changed with version 2.1.13. The change is that the URL column is now a TEXT field to allow for longer URLs. If you have an old system you may want to manually change that column; there is no migration included to perform that update.

Install

Via Composer

composer require jdavidbakr/mail-tracker

Publish the config file and migration

php artisan vendor:publish --provider="jdavidbakr\MailTracker\MailTrackerServiceProvider"

Run the migration

php artisan migrate

Note: If you would like to use a different connection to store your models, you should update the mail-tracker.php config entry connection before running the migrations.

If you would like to use your own migrations, you can skip this library migrations by calling MailTracker::ignoreMigrations(). For example:

// In AppServiceProvider

public function boot()
{
    MailTracker::ignoreMigrations();
}

Usage

Once installed, all outgoing mail will be logged to the database. The following config options are available in config/mail-tracker.php:

name: set your App Name.
inject-pixel: set to true to inject a tracking pixel into all outgoing html emails.
track-links: set to true to rewrite all anchor href links to include a tracking link. The link will take the user back to your website which will then redirect them to the final destination after logging the click.
expire-days: How long in days that an email should be retained in your database. If you are sending a lot of mail, you probably want it to eventually expire. Set it to zero to never purge old emails from the database.
route: The route information for the tracking URLs. Set the prefix and middlware as desired.
admin-route: The route information for the admin. Set the prefix and middleware.
admin-template: The params for the Admin Panel and Views. You can integrate your existing Admin Panel with the MailTracker admin panel.
date-format: You can define the format to show dates in the Admin Panel.
content-max-size: You can overwrite default maximum length limit for content database field. Do not forget update it's type from text if you need to make it longer.

If you do not wish to have an email tracked, then you can add the X-No-Track header to your message. Put any random string into this header to prevent the tracking from occurring. The header will be removed from the email prior to being sent.

\Mail::send('email.test', [], function ($message) {
    // ... other settings here
    $message->getHeaders()->addTextHeader('X-No-Track',Str::random(10));
});

Storing content of mails in filesystem

By default, the content of an e-mail is stored in the content column in the database so that the e-mail can be viewed after it has been sent. If a lot of emails are sent, this can consume a lot of memory and slow down the database overall. It is possible to specify in the configuration that the content should be saved to a file in the file system.

    'log-content-strategy' => 'filesystem',
    'tracker-filesystem' => null
    'tracker-filesystem-folder' => 'mail-tracker',

To use the filesystem you need to change the log-content-strategy from database to filesystem. You can specify the disk with tracker-filesystem and the folder it should store the file in with tracker-filesystem-folder.

Overriding models

In some cases you want to override the built-in models. You can do so easily for example in you AppServiceProvider with

MailTracker::useSentEmailModel(YourOwnSentEmailModel::class);
MailTracker::useSentEmailUrlClickedModel(YourOwnSentEmailUrlClickedModel::class);

Your model should implement to SentEmailModel or SentEmailUrlClickedModel interface. This package provides traits to easily implement your own models but not have to reimplement or copy existing code.

use Illuminate\Database\Eloquent\Model;
use jdavidbakr\MailTracker\Concerns\IsSentEmailModel;
use jdavidbakr\MailTracker\Contracts\SentEmailModel;

class OwnEmailSentModel extends Model implements SentEmailModel {
    use IsSentEmailModel;

    protected static $unguarded = true;

    protected $casts = [
        'meta' => 'collection',
        'opened_at' => 'datetime',
        'clicked_at' => 'datetime',
    ];
}

Skip Tracking for Specific Emails

If you have a specific email that you do not want to track, you can add the X-No-Track header to the email. This will prevent the email from being tracked. The header will be removed from the email prior to being sent.

In laravel 9 onwards you can introduce a headers method to your Mailable class. This will stop the tracking pixel/click tracking from applying to the Mailable

public function headers()
{
    return [
        'X-No-Track' => Str::random(10),
    ];
}

Skipping Open/Click Tracking for Anti-virus/Spam Filters

Some mail servers might scan emails before they deliver which can trigger the tracking pixel, or even clicked links. You can add an event listener to the ValidActionEvent to handle this.

class ValidUserListener {
    public function handle(ValidActionEvent $event)
    {
        if (in_array(request()->userAgent(), ['Mozilla/5.0', 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.135 Safari/537.36 Edge/12.246 Mozilla/5.0']) {
            $event->skip = true;
        }
    }
}

Ensure you add the listener to the ValidActionEvent in your EventServiceProvider, if you aren't using automatic event discovery.

## Note on dev testing

Several people have reported the tracking pixel not working while they were testing. What is happening with the tracking pixel is that the email client is connecting to your website to log the view. In order for this to happen, images have to be visible in the client, and the client has to be able to connect to your server.

When you are in a dev environment (i.e. using the `.test` domain with Valet, or another domain known only to your computer) you must have an email client on your computer. Further complicating this is the fact that Gmail and some other web-based email clients don't connect to the images directly, but instead connect via proxy. That proxy won't have a connection to your `.test` domain and therefore will not properly track emails. I always recommend using [mailtrap.io](https://mailtrap.io) for any development environment when you are sending emails. Not only does this solve the issue (mailtrap.io does not use a proxy service to forward images in the emails) but it also protects you from accidentally sending real emails from your test environment.

## Events

When an email is sent, viewed, or a link is clicked, its tracking information is counted in the database using the jdavidbakr\MailTracker\Model\SentEmail model. This processing is done via dispatched jobs to the queue in order to prevent the database from being overwhelmed in an email blast situation. You may choose the queue that these events are dispatched via the `mail-tracker.tracker-queue` config setting, or leave it `null` to use the default queue. By using a non-default queue, you can prioritize application-critical tasks above these tracking tasks.

You may want to do additional processing on these events, so an event is fired in these cases:

-   jdavidbakr\MailTracker\Events\EmailSentEvent
    - Public attribute `sent_email` contains the `SentEmail` model
-   jdavidbakr\MailTracker\Events\ViewEmailEvent
    - Public attribute `sent_email` contains the `SentEmail` model
    - Public attribute `ip_address` contains the IP address that was used to trigger the event
-   jdavidbakr\MailTracker\Events\LinkClickedEvent
    - Public attribute `sent_email` contains the `SentEmail` model
    - Public attribute `ip_address` contains the IP address that was used to trigger the event
    - Public attribute `link_url` contains the clicked URL

If you are using the Amazon SNS notification system, these events are fired so you can do additional processing.

-   jdavidbakr\MailTracker\Events\EmailDeliveredEvent (when you received a "message delivered" event, you may want to mark the email as "good" or "delivered" in your database)
    - Public attribute `sent_email` contains the `SentEmail` model
    - Public attribute `email_address` contains the specific address that was used to trigger the event
-   jdavidbakr\MailTracker\Events\ComplaintMessageEvent (when you received a complaint, ex: marked as "spam", you may want to remove the email from your database)
    - Public attribute `sent_email` contains the `SentEmail` model
    - Public attribute `email_address` contains the specific address that was used to trigger the event
-   jdavidbakr\MailTracker\Events\PermanentBouncedMessageEvent (when you receive a permanent bounce, you may want to mark the email as bad or remove it from your database)
    jdavidbakr\MailTracker\Events\TransientBouncedMessageEvent (when you receive a transient bounce.  Check the event's public attributes for `bounce_sub_type` and `diagnostic_code` to determine if you want to do additional processing when this event is received.)
    - Public attribute `sent_email` contains the `SentEmail` model
    - Public attribute `email_address` contains the specific address that was used to trigger the event

To install an event listener, you will want to create a file like the following:

```php
<?php

namespace App\Listeners;

use jdavidbakr\MailTracker\Events\ViewEmailEvent;

class EmailViewed
{
    /**
     * Create the event listener.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Handle the event.
     *
     * @param  ViewEmailEvent  $event
     * @return void
     */
    public function handle(ViewEmailEvent $event)
    {
        // Access the model using $event->sent_email
        // Access the IP address that triggered the event using $event->ip_address
    }
}

<?php

namespace App\Listeners;

use jdavidbakr\MailTracker\Events\PermanentBouncedMessageEvent;

class BouncedEmail
{
    /**
     * Create the event listener.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Handle the event.
     *
     * @param  PermanentBouncedMessageEvent  $event
     * @return void
     */
    public function handle(PermanentBouncedMessageEvent $event)
    {
        // Access the email address using $event->email_address
    }
}

Then you must register the events you want to act on in your \App\Providers\EventServiceProvider $listen array:

/**
 * The event listener mappings for the application.
 *
 * @var array
 */
protected $listen = [
    'jdavidbakr\MailTracker\Events\EmailSentEvent' => [
        'App\Listeners\EmailSent',
    ],
    'jdavidbakr\MailTracker\Events\ViewEmailEvent' => [
        'App\Listeners\EmailViewed',
    ],
    'jdavidbakr\MailTracker\Events\LinkClickedEvent' => [
        'App\Listeners\EmailLinkClicked',
    ],
    'jdavidbakr\MailTracker\Events\EmailDeliveredEvent' => [
        'App\Listeners\EmailDelivered',
    ],
    'jdavidbakr\MailTracker\Events\ComplaintMessageEvent' => [
        'App\Listeners\EmailComplaint',
    ],
    'jdavidbakr\MailTracker\Events\PermanentBouncedMessageEvent' => [
        'App\Listeners\BouncedEmail',
    ],
];

Passing data to the event listeners

Often times you may need to link a sent email to another model. The best way to handle this is to add a header to your outgoing email that you can retrieve in your event listener. Here is an example:

/**
 * Send an email and do processing on a model with the email
 */
\Mail::send('email.test', [], function ($message) use($email, $subject, $name, $model) {
    $message->from('from@johndoe.com', 'From Name');
    $message->sender('sender@johndoe.com', 'Sender Name');
    $message->to($email, $name);
    $message->subject($subject);

    // Create a custom header that we can later retrieve
    $message->getHeaders()->addTextHeader('X-Model-ID',$model->id);
});

and then in your event listener:

public function handle(EmailSentEvent $event)
{
    $tracker = $event->sent_email;
    $model_id = $event->sent_email->getHeader('X-Model-ID');
    $model = Model::find($model_id);
    // Perform your tracking/linking tasks on $model knowing the SentEmail object
}

Note that the headers you are attaching to the email are actually going out with the message, so do not store any data that you wouldn't want to expose to your email recipients.

Exceptions

The following exceptions may be thrown. You may add them to your ignore list in your exception handler, or handle them as you wish.

jdavidbakr\MailTracker\Exceptions\BadUrlLink - Something went wrong with the url link. Basically, the system could not properly parse the URL link to send the redirect to.

Amazon SES features

If you use Amazon SES, you can add some additional information to your tracking. To set up the SES callbacks, first set up SES notifications under your domain in the SES control panel. Then subscribe to the topic by going to the admin panel of the notification topic and creating a subscription for the URL you copied from the admin page. The system should immediately respond to the subscription request. If you like, you can use multiple subscriptions (i.e. one for delivery, one for bounces). See above for events that are fired on a failed message. For added security, it is recommended to set the topic ARN into the mail-tracker config.

Views

When you run the php artisan vendor:publish command, simple views will add to your resources/views/vendor/emailTrakingViews that you can customize. You of course my build your entire admin pages from scratch using these views as a guide.

Admin Panel

MailTracker comes with a built-in administration area. The default configuration that is published with the package puts it behind the can:see-sent-emails middleware; you may create a gate for this rule or change it to use one of your own. You may also change the default prefix as well as disable the admin routes completely.

The route name is 'mailTracker_Index'. The standard admin panel route is located at /email-manager. You can use route names to include them into your existing admin menu. You can customize your route in the config file. You can see all sent emails, total opens, total urls clicks, show individuals emails and show the urls clicked details.

All views (email tamplates, panel) can be customized in resources/views/vendor/emailTrakingViews.
