Why Legitimate Senders End Up on Blocklists - CSA Live Webinar 2026

You’re doing everything right. At least... everything you know to do. You’re following best practices. Your authentication is solid. You haven’t changed a thing. So why are you on a blocklist? In this fireside chat, Lauren and Melinda explore the gap between what senders believe is “doing everything right” and how their behavior is actually interpreted. The email ecosystem has evolved... threats have shifted, sending environments are more complex, and the signals many teams rely on to monitor performance don’t always tell the full story. This session breaks down how legitimate programs end up exposed without realizing it — and how to reduce that risk. What You’ll Learn: Why following best practices isn’t always enough to stay off blocklists The types of issues that commonly blindside legitimate senders Where traditional monitoring signals fall short (and create false confidence) Practical ways to identify gaps and reduce exposure Session Format: Conversational session with questions addressed throughout and dedicated time for Q&A at the end. The discussion will move through four key areas: The landscape has changed... even if your program hasn’t The threats you don’t see coming... and how they show up The signals you rely on may be misleading you What to do about it... practical ways to reduce risk Speakers: Lauren Meyer, Founder, Send It Right Melinda Plemel, Senior Consultancy Specialist, Spamhaus Certified Senders Alliance ➜ https://certified-senders.org/
