You are advised to avoid using any of the words below in your subject line, since they have been known to contribute to spam scores. You should also not try to disguise these keywords by joining words together or splitting them in two, as the spam filters will still pick them up.
This does not mean that any single one will automatically trigger a spam filter, but the more you use, the higher your spam score will be, and the lower the chances of your email reaching the inbox.
