How do I stop notifications from spam?

Hello Raina, I think you might have misunderstood my question. I want notifications for messages, I do not want notifications for filtered out messages.

To rephrase my problem, I am getting spam from email addresses that are sent to 20 phone numbers in a group chat. I am one of the 20 people. So each person that replies with "stop", "unsubscribe" or whatever- my phone will notify me of their reply. I have the conversation filtered but I am still getting notifications.

With multiple group chats being sent each day, I am getting literally dozens of irrelevant notifications.

Man I'm really not explaining this well. Each time somebody replies to the group, it splinters that message into a seperate group chat. I'm not sure if it's because the person replying isn't using iMessage, or because the message is filtered out, or because the group originated from an email address, or something else entirely. But it sounds like from your suggestion, if I want to end the notifications I'll have to continuously hide the alerts of every splintered conversation that begins because somebody replied to the group? Or I can go into the group list and manually block the numbers of everyone involved?

Here is a video illustrating what I'm talking about.

You can see me open up several chat windows- each one contains no chat history. But when I explore the recipients of the chat, I can see the numbers are all the same and they all reference the email address that began the chat.
