How do deliverability professionals collaborate cross-industry?

If you've ever felt like you're fighting email problems alone, you're not. Deliverability is a small industry, and the professionals in it talk to each other more than you'd think, even when they work for competing companies.

The most important formal venue is M3AAWG (the Messaging, Malware and Mobile Anti-Abuse Working Group). Three times a year, engineers and deliverability leads from mailbox providers, ESPs, security firms, and brands sit in the same room to share intelligence about abuse patterns, authentication gaps, and emerging threats. Sessions are confidential by design, which is exactly why the conversations are honest. You won't find the same candor in a public forum.

For day-to-day community, Email Geeks Slack is where a lot of working deliverability professionals actually hang out. There are channels for authentication, postmaster questions, ESP comparisons, and general troubleshooting. It's free to join, and the signal-to-noise ratio is genuinely high. Someone's usually been through whatever you're dealing with.

Then there are the standard-setting tracks. The IETF publishes RFCs that define how email protocols work, and their mailing lists are public. You don't need credentials to follow along or comment. IANA manages the registries that underpin those standards. These aren't casual conversations, but if you want to contribute to where email is heading, this is where it happens.

Industry associations like the DMA and EEC publish best practices guides and run working groups focused on responsible marketing. These tend to be more accessible for non-engineers and often shape what compliance expectations look like in your region.

The reason all of this matters is that email threats move fast. A new phishing pattern, a sudden change in filtering logic, a blocklist shifting its criteria. When professionals share what they're seeing across organizations, the whole ecosystem responds faster than any single team could. You benefit from the pattern recognition of thousands of senders, not just your own data.

Still if you're just starting out, the practical path is to join Email Geeks Slack first (free, immediate, useful), follow the major conferences to see what topics keep surfacing, and if your role supports it, look into applying for M3AAWG membership once you have something real to contribute. Showing up with questions is fine. Showing up with data is better.
