Sending email claims message is spam

I’m trying to respond to a message from Western Digital but eM Client won’t send, claiming it has spam content. What gives. How do I get this remedied?

Sounds like something in the body or header of the email your SMTP mail server doesn’t like and is bouncing it back.

I would suggest to contact your specific mailbox technical support via their website and let them know the email message that is getting rejected for spam reasons. They can then help you.

The bounces only occur with eM Client.

It’s nothing to do with eM Client.

As per the message says your SMTP server has rejected it for spam content. You need to speak to your mail server support and advise them.
