Is a link or the domain name you are sending in your emails listed on the SpamHaus Domain Block List (DBL)?
This is a very common occurrence for any site that is being used for marketing, it is very simple for an recipient to complain about a domain inside of an email and as result the domain will be listed on the SpamHaus DBL. This happens to a lot of hosted customers, even ones who do not do outbound marketing.
There is a very simple fix for this which has to be done by the owner of the website.
If you are not the owner of the domain name causing your email to get filtered..
1. contact the owner of that domain with a link to this article.
2. post the content you are linking to on a different domain name so that you can send your message without being dependant on another parties domain.
