Laravel notification options to avoid spamming?

Question

Laravel

Greetings.
I send a notification if there is a new comment in the ticket. For example, not immediately, but every 15 minutes. It often happens that you have to leave 2 or more in a row for one addressee.
In order not to spam, you need to send only one notification.

Only use of the queue table and the scheduler comes to mind.

Answer 1

Pass the ticket_id to the notification and then check for unread user notifications.
