With all the email filtering programs in effect it seems like escaping being filtered is near impossible. In order to avoid the filter, address the most common words used to block emails and prevent using them. The best way to get through an email filter is to understand the ways you are being filtered, so take a look at the key 20 words to avoid when sending out emails as courteously provided by:
1. cancel at any time 2. check or money order 3. click here 4. congratulations 5. dear friend 6. e-mail marketing 7. for only 8. free (including toll-free) 9. great offer 10. guarantee 11. increase sales 12. order now 13. promise you 14. risk free 15. special promotion 16. this is not spam 17. to be removed 18. unsubscribe 19. winner 20. amazing
Not using these words is difficult and sometimes unavoidable but do your best and you will see the amount of bounced emails drop drastically.
