Block sender mail mac 10.14

To block a sender's email on a Mac running macOS High Sierra (10.14), you can follow these steps:

Method 1: Using the Mail app

1. Open the Mail app on your Mac.
2. Click on the "Mail" menu and select "Preferences" (or use the keyboard shortcut Command + Comma).
3. Click on the "Rules" tab.
4. Click the "+" button at the bottom left corner of the window to create a new rule.
5. Select "Match" and then "From" from the dropdown menu.
6. Enter the email address of the sender you want to block in the "Contains" field.
7. Click the "OK" button.
8. Click the "Apply" button to apply the rule to all messages from the blocked sender.

Method 2: Using the Junk Mail filter

1. Open the Mail app on your Mac.
2. Click on the "Mail" menu and select "Preferences" (or use the keyboard shortcut Command + Comma).
3. Click on the "Junk Mail" tab.
4. Select the "Move it to the Junk Mail folder" option.
5. Click the "Add" button next to "Sender" and enter the email address of the sender you want to block.
6. Click the "OK" button.
7. The Junk Mail filter will automatically move emails from the blocked sender to the Junk Mail folder.

Method 3: Using a third-party email client

If you're using a third-party email client like Microsoft Outlook or Mozilla Thunderbird, you may need to follow the client's specific instructions for blocking senders.

Note: Blocking a sender's email address will not prevent them from sending you emails, but it will move their emails to the Junk Mail folder or apply a rule to them. If you want to completely block a sender's emails, you may need to use a different method, such as setting up a filter in your email provider's web interface or using a third-party email filtering service.
