Deliverability
Amazon SES deliverability: DMARC, BIMI and IP warm-up done right
The DNS records, the warm-up curve, the complaint thresholds Gmail and Yahoo enforce, and the subdomain strategy that keeps marketing away from your password resets.
What the guide covers
Authenticate properly
DKIM 2048-bit, SPF alignment and DMARC moved to p=reject in stages. Monitor for DNS drift.
Split your streams
Transactional and marketing on separate subdomains and IP pools. A campaign complaint must never delay a reset link.
Warm-up curve
Thirty days, per-provider, throttling automatically when complaints or bounces spike.
The thresholds that matter
Keep complaints under 0.08% and hard bounces under 2%. Above that, providers throttle before they tell you.
BIMI
Only after DMARC enforcement. It buys recognition in the inbox, not deliverability by itself.
Monitoring
Seed-list placement per provider plus Google Postmaster and Yahoo feedback in one view.
Why we publish rates and policy dates

- Every rate carries the date it was verified against Meta
- Policy changes are re-checked quarterly and corrected in public
- Each answer stands alone so assistants can quote it accurately
- No gated PDF — the whole thing is on the page
