Download the PHP package oriceon/mail-tracker without Composer

Laravel Mail Tracker

Mail Tracker 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.

Install

Via Composer

Publish the config file and migration

Run the migration

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:

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.

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.

Storing content of mails in filesystem

By default, the content of an e-mail is stored in the message 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.

` To use the filesystem you need to change thelog-message-strategyfromdatabasetofilesystem. You can specify the disk withtracker-filesystemand the folder it should store the file in withtracker-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

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

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

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.

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 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 OriceOn\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:

• OriceOn\MailTracker\Events\EmailSentEvent
  • Public attribute sent_email contains the SentEmail model
• OriceOn\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
• OriceOn\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.

• OriceOn\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
• OriceOn\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
• OriceOn\MailTracker\Events\PermanentBouncedMessageEvent (when you receive a permanent bounce, you may want to mark the email as bad or remove it from your database) OriceOn\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:

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

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:

and then in your event listener:

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.

• OriceOn\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.
