Avoid looking like a spammer: the Spamhaus perspective

Speaker: Annalivia Ford, Senior Threat Analyst, Spamhaus
If you're sending email with good intentions and still getting listed by spam filters, no doubt it’s frustrating.
On the flip side, to successfully take advantage of victims, bad actors are becoming more sophisticated. They set the bar for defining what spam is. If your behavior falls short of their bar, you need to improve your sending practices; remember - intentions matter far less than behavior.
But what is the bar? What action will help you avoid getting listed?
In this session, we'll share the fundamentals - without these basics, no spam filter will understand the difference, even with authenticated, confirmed opt-in (COI) emails. We'll cover:
• Setting up:
• Authentication
• Limiting domain usage
• DNS naming schemes
• Properly registering domains
• Contiguous IPs
• Sending once established:
• Taking action with 5XX return codes
• Sending patterns
• Honoring suppression lists
• Importance of known users
• Sending metrics
• The danger of attachments
• Real-world examples of (potentially) good intention, but bad behavior
• What to do if you do get listed by Spamhaus
• Q&A
