During the review stage of your campaign you will receive a SPAM score for your campaign based on its content. This test puts your campaign up against the Spam Assassin’s SPAM filter. The following are a few of the most commonly encountered rules in the Spam Assassin spam filter test.
BODY: HTML: images with 2400-2800 bytes of words / BODY: HTML has a low ratio of text to image area
This basically means that your campaign has a large area of images and does not have enough text content for balance. To fix this problem, add more text in your email. Also, text inside of images will not count as text as SPAM filters cannot read images.
BODY: Message only has text/html MIME parts / Multipart message only has text/html MIME parts
All messages sent from Total Send are multipart messages. Some SPAM filters don’t trust you if you do not have both an HTML version and plain text version of your message. Their reasoning is that spammers are lazy and will not take the time to make both as their emails are disposable. It is good practice to use both and HTML and plain-text version of your campaigns.
BODY: Talks about (trigger word)
This basically means that you’ve used a spam trigger word in your email that is “taboo”. These words are usually things like “cash, affiliate, discount etc.” To fix this, just get a bit creative and find another way of saying it.
