Copywriting for email: Shirk the spam filters

Do you ever wonder why some of the emails that you get are from someone you don't know and have words that are mixed with symbols such as ^free^ grant money or Check your --credit-- score today! 

One word comes to your mind: Spam. Professional copywriters for email marketing campaigns know that when the first thing to consider when sending emails to subscribers is to make sure the email gets delivered, then opened. Sometimes, you can't avoid using words like "free" or "opportunity".

Just FYI, these words usually go straight to the spam filter before it gets to your subscriber's inbox.

Don't waste precious words by writing them without giving a thought as to whether your subscribers will actually be able to receive them.

So how to get around this obstacle? Use words that are not likely to be considered by spam filters as spam.
