13 views September 11, 2026

Getting an email marked as "delivered" doesn't mean it reached the inbox. In this session, Austin Helm from ZeroBounce breaks down email deliverability, inbox placement, sender reputation, and the steps marketers can take to keep legitimate emails out of the spam folder. You'll learn how to: ✦ Understand the difference between email delivery and email deliverability ✦ Configure SPF, DKIM, and DMARC to authenticate your sending domain ✦ Build a domain strategy that separates higher-risk sending activity from important customer communications ✦ Protect your sender reputation by sending relevant content to people who expect to hear from you ✦ Improve email list hygiene by validating addresses, removing bounced emails, and regularly cleaning your database ✦ Understand how organic, opted-in, and purchased email data can affect deliverability ✦ Monitor bounce rates, spam complaints, opens, and other signals that can reveal deliverability problems ✦ Build ongoing email hygiene habits instead of treating deliverability as a one-time project The key takeaway: strong email deliverability comes from consistently sending wanted, relevant messages to healthy email addresses from properly configured domains. Authentication, list quality, content, engagement, and ongoing monitoring all work together to build or damage your sender reputation over time. 00:00 Introduction 01:12 Email Deliverability Fundamentals 02:41 Delivery vs. Deliverability 04:57 SPF, DKIM & DMARC Authentication 06:57 Building a Healthy Sender Reputation 09:13 Creating a Safe Sending Domain Strategy 12:13 Email Validation & List Hygiene 15:15 Monitoring Bounce Rates & Deliverability 17:01 Email Deliverability Mistakes to Avoid 20:12 Building an Email Hygiene Routine 21:54 ZeroBounce & Customer.io 23:26 Audience Q&A 30:04 Wrap-Up
