MailList Controller send email messages in the same
format as your regular email client does. The
message format, message encoding or the mailer
itself is not the problem. In most cases the content
of the message is the reason why a newsletter
message gets detected as spam.
Please check your message content and subject:
-
avoid
typical spam terms like "business
offer"
-
include
a plain-text part(!) when sending out HTML
messages
-
avoid
inline images with only a few words of text
-
use
png images instead of gif images
Its also recommended to send a test message to a
spam-protected email account and/or a webmail
(e.g. freemail) account to verify the spam rating of
the message.
Send
out your newsletter email
messages to subscribers only and allow them to
unsubscribe!
Common
issues:
The header often contains details about the
spam-rating:
e.g.
1.1 MPART_ALT_DIFF BODY: HTML
and text parts are different
Include a plain-text part to your HTML message. (use
the "Extract ..." function)
1.2
TVD_FW_GRAPHIC_NAME_MID BODY:
TVD_FW_GRAPHIC_NAME_MID
Rename the inline image e.g. use 1.gif instead of
header.gif
1.4
SARE_GIF_ATTACH FULL: Email has a inline gif
Use a different format e.g. PNG instead of the GIF
image.
0.8
HTML_TITLE_SUBJ_DIFF HTML_TITLE_SUBJ_DIFF
Replace the title tag in the html sourcecode.
(remove <title> ... </title>)
1.3
MISSING_SUBJECT Missing Subject: header

text to image area
2.5 HTML_IMAGE_ONLY_16 BODY: HTML: images with
