There are some concrete and practical tips to prevent your emails being classified as SPAM will help optimize the reception and conversion ratio of their email marketing campaigns:

Also does the same thing with email marketing messages that are received and are considered as not spam.
When we have trained our Bayesian filter with many words associated with the practice of non-spam and spam, we ask that automatically calculates the probability that each e-mail is received whether or not spam based on words containing, for example, "viagra" or "free", "enlarge." This calculates the probability that the message is spam. This figure is called "spamicidad" and when it exceeds a threshold (eg 90%) can be safely classified as spam.
Once trained, a Bayesian filter offers very few false positives, because unlike other filters, attacks the essence of the problem of spam: the message content. Remember that the Bayesian method is multilingual and international, a Bayesian spam filter, being adaptive, can be used with any language.
