What is Inbox Expo?
Still have a question, spotted an error, or have a better explanation or a source we should cite?
Inbox Expo is an annual conference built specifically around email deliverability and strategy. It's one of the few events where you can sit across from people who actually work at the major mailbox providers (MBPs) like Gmail, Outlook, and Yahoo Mail and ask them direct questions about filtering decisions, policy changes, and what gets email blocked.
That MBP access is what sets Inbox Expo apart from general marketing conferences. Most events talk about deliverability in the abstract. Inbox Expo puts practitioners in the same room as the people who actually run the inboxes.
Sessions tend to cover the technical side of things like email authentication, filtering algorithms, and sender reputation, alongside more strategic topics like program management and audience engagement. You'll also find practitioner case studies from senders who've been through the trenches and came back with lessons worth hearing.
If you work in deliverability day to day, it's genuinely useful. If you're newer to the field, it can feel dense, but even that's a feature (you'll leave with a reading list and a few contacts who've already solved the problems you're about to face).
For a broader look at where deliverability professionals gather, the Festival of Email and M3AAWG are worth comparing depending on what you're looking for.
