Newsletter spam and advertisers

If you send out a newsletter, or other email marketing materials, one of the biggest issues you face is getting the message through spam and related filters.

As well as choosing your words carefully to avoid being classed as spam, you also need to watch what advertising you add to your newsletter.

Setting rules on the type of advertising you accept is a different topic, but it is also important to check what words any advertisers use – you don’t want to put time into adjusting your words just to have many spam triggers in ads. Ensure your advertisers understand you have editorial control over their ads, although major changes need their approval.

Apparently you also need to be aware of how your advertisers are viewed online. That is, if you include an advertiser’s URL that has been blacklisted by ISPs for sending spam, your newsletter could also be filtered out.

Some sites that help identify blacklisted email senders are:

MX Toolbox (based on server IP addresses)
Abusive hosts blocking list(based on host name or IP address)
DNS Stuff (based on DNS servers – not free)
Black List Monitoring (based on IP address)

* I don’t know that these are the best, but if they help you avoid being blacklisted (or recover from being blacklisted) they may be worth a try!
