What happened
Analysis of DNS records for the top million domains shows self-hosted email dropped from 44.6% in 2016 to 22.4% in 2026, while Google Workspace (21.8%) and Microsoft 365 (16.8%) now handle 38.6% combined. Researcher Artem Berezin warns that centralization means a single outage, filtering change, or policy decision at either provider propagates instantly across the ecosystem, with no graceful fallback for rejected messages.
Why it matters
If you run a SaaS or startup that depends on email deliverability for onboarding, transactional alerts, or support, your fate increasingly rests on two providers' spam-filtering policies. Consider diversifying your email infrastructure or at least monitoring deliverability separately for Google vs Microsoft recipients rather than treating email as a solved problem.
Discussion angle
For Malaysian founders shipping transactional email, what's the practical risk of Google/Microsoft dominance—should you test deliverability per-provider, and does self-hosting still make sense for any use case?
