Avoid using Spam Filtering Words in your content

• Avoid Spam Filters That Flag The “To Unsubscribe” and “To be removed” Phrases – Do not use these phrases in your removal notice. A number of spam filters flag emails containing that particular word as possible spam. The reason is many spammers now offer “unsubscribe” functions that don’t actually do anything. Read alternative phrases you can use instead of “To Unsubscribe” and “To be removed“.
• Avoid Spam Filters That Flag Chain Letters – Some spam filters are flagging emails that asks readers to forward the newsletter on as chain letters.
  Avoid using the word “forward” and any of the following words in the same sentence, “all, anyone, every, friends, many, others, people.” Instead of “forward,” try using “pass,” “share,” or “send.”

Ask your email software company what relationships they have with major email companies. You may have to pay more for these services but it maybe well worth it.
