how to avoid "[bulk]" in subject line?

[willymmm]

I did a test of an email (3 recipients)
On the one verizon email address, [bulk] is prepended to the subject.

How do I avoid this?

Thanks, Bill

Try to edit your message and avoid spam-like words or sentences. You can also use built-in spam checker.

I did use spam checker.

It seems that only yahoo/verizon is adding the (bulk] flag.

They add this because they think the message is a bulk message. Now you have to find out why. Try with other types of messages.
