How block unwanted emails on iPhone

To block unwanted emails on an iPhone, you can follow these steps:

Block the sender

Open the Mail app and go to the email from the sender you want to block. Tap on the sender's name or email address at the top of the email. A contact card will appear; tap on "Block this Contact" at the bottom of the screen.

Move emails to the trash automatically

After blocking the sender, you can ensure their future emails are automatically sent to the trash.

Go to Settings > Mail > Blocked Sender Options and select "Move to Trash."

Use filters

Alternatively, you can create rules on your desktop in iCloud or another email client to filter or move unwanted emails directly to the trash.
