New in Symfony 5.2: Notifier improvements

Warning: This post is about an unsupported Symfony version. Some of this information may be out of date. Read the most recent Symfony Docs.

The Notifier component sends notifications via one or more channels (email, SMS and chats like Slack and Telegram). In Symfony 5.2 we’ve improved it with the following features.

Symfony profiler integration

One of the main missing features of the Notifier component was the lack of integration with the Symfony debug toolbar and profiler. In Symfony 5.2 we’ve fixed that. First, the debug toolbar now displays the number of sent notifications and the channels used to send them:

Symfony Notifier Web Debug Toolbar

If you click on that toolbar section, you can see the new Notifier panel in the Symfony Profiler, which displays a summary of the notification activity:

Symfony Notifier Web Debug Profiler Metrics

You can also inspect the full details of all sent notifications:

Return sent messages

In previous Symfony versions, the send() method of each notifier didn’t return anything. Starting from Symfony 5.2 they return a Symfony\Component\Notifier\Message\SentMessage object, which provides access to the original message and transport and to the ID of the sent message, making it easier to debug.

New integrations

The Notifier component already integrates with lots of third-party services, but in Symfony 5.2 we’ve added a ton of new integrations:

As with any Open-Source project, contributing code or documentation is the most common way to help, but we also have a wide range of sponsoring opportunities.


Very useful these new additions, thank you! But in the details of the notifications sent, we can see the recipient's email address? @Jan
Awesome work guys!
But in the "new Integration" section.
Mobyt SMS in PR #36648 is by Deamon in fact (copy paste error?).
@Thomas you are right! This was a copy+paste error but it's now fixed. Thanks!
Any chance the Notifier component will get integration with the Mercure component?
SentMessage object really makes debugging easier - Great job :)
Awesome work; thank you all for the new integrations
