Hello wadesertdog17,
We would like to see how we can help you with your emails. Our previous links are all for iPhone 8's, not just newer models. For help with spam text visit: Block, filter, and report messages on iPhone - Apple Support
"Block messages from a specific person or number
- In a Messages conversation, tap the name or number at the top of the conversation.
- Tap the
info button, scroll down, then tap Block this Caller.
To view and manage your list of blocked contacts and phone numbers, go to Settings
> Messages > Blocked Contacts. See the Apple Support article Block phone numbers, contacts, and emails on your iPhone, iPad, or iPod touch.
Filter messages from unknown senders
With iMessage, you can filter messages from unknown senders, and you won’t get notifications from them.
Go to Settings
> Messages, scroll down to Message Filtering, then turn on Filter Unknown Senders.
When this setting is on, you can only see messages from people who aren’t in your contacts when you go to Filters > Unknown Senders.
Note: You canʼt open any links in a message from an unknown sender until you add the sender to your contacts or reply to the message."
Cheers!
