You put so much work into your email marketing campaigns. Yet, it can be all for naught if it they never reach the inbox. If this sounds like you, perhaps you’ve been blacklisted.

Blacklists are comprised of IP addresses or domains that are blocked from accessing a specific network. There are numerous blacklists on the Internet. Some literally list every single email marketer alive (and possibly dead)—yet carry little to no weight at all with ISPs. Others should be avoided at all costs, including:

1. Spamhaus

Domains and IP addresses with poor sender reputation are listed publicly here. Content reflecting spam and spam traps are monitored through this blacklist.

2. SORBS

More than 200,000 companies use SORBS blacklist. Several ISPs and corporations all over the world use this blacklist as part of their filtering system for their networks. It recognizes undesirable senders through partner spam reports and spam traps.

3. SpamCop
