Unlocking the Inbox: Strategies for Email Deliverability in the Future

Julia Janssen-Holldiek

As the digital landscape continues to evolve, ensuring that commercial mass emails reach the inbox and not the spam folder is more critical than ever. In this session, Julia will share practical strategies for email senders who want to maintain high inbox placement rates in 2026 and beyond. The focus will be on building trust—with both recipients and mailbox providers—to ensure that emails are welcomed rather than blocked. Email deliverability, the backbone of effective email marketing, will be explored in detail, highlighting how adherence to best practices and self-regulatory systems like the Certified Senders Alliance (CSA) can help sustain sender reputation. Think of mailbox providers as the bouncers of an exclusive club—only those with the right credentials are allowed in. This talk will provide actionable insights into how to meet the evolving demands of email deliverability, allowing businesses to use email as a powerful tool for communication and revenue generation.
