Microsoft SNDS data appears in the Deliverability Center for Amazon SES senders
What changed: For workspaces that send email through Amazon SES, Braze’s Deliverability Center now displays Microsoft SNDS metrics for dedicated sending IPs, and backfills up to 90 days of history when the feature is switched on for the workspace.
Why it matters: SNDS is the only place Microsoft tells you what it thinks of your IP — complaint rate, trap hits, filter result — and most senders never look, because it lives behind a separate registration on a Microsoft site nobody has open. Putting it in the tool people already have open is the difference between knowing and guessing. Read the scope before you celebrate: dedicated IPs, and only for workspaces on Amazon SES.
Do next: Switch it on and read the backfilled 90 days before you read anything else. If your complaint rate at Outlook was already high, the history will show you the week it started, which is usually the week something else changed.
