Locate the unwanted message in the eM Client message list and right-click on it. From the context menu click on “Move to junk” which will move the selected message to the spam folder right away or hover over “Move to Junk” for additional blacklist options:

Move to Junk and blacklist email – Moves messages to the dedicated spam folder within the respective email account and adds the email address of the sender to the blacklist to prevent them from reaching you again.

Move to Junk and blacklist domain – Also moves the message to the dedicated spam folder but instead of blocking the specific address, the entire domain is blocked. So for example, if you block the message sent from the domain, no other messages sent from addresses at will reach your mailbox.

Both of these options will help you to prevent spam from reaching your mailbox but it’s important to take a little bit of caution to avoid blocking popular email provider's domains when using “Move to Junk and blacklist domain”.
