Whitelist SES Sending IP Ranges
Amazon SES does not use a fixed “Urban SDK” IP pool—instead it publishes its current sending ranges in AWS’s global IP list.
Automatic sync
- Periodically pull https://ip-ranges.amazonaws.com/ip-ranges.json
- Filter entries where "service":"SES" (and your region, e.g. "region":"us-east-1")
- Programmatically update your firewall to allow each "ip_prefix" in that subset
- ⚠️ These will change—be sure to re-sync from ip-ranges.json at least every 3 months.
SPF Record
Ensure your domain’s SPF policy includes Urban SDK’s sending servers. Add or update your SPF record to include:
- include:spf.urbansdk.com
DKIM & DMARC
- If you enforce DKIM: add Urban SDK’s DKIM public key to your DNS under the selector urbansdk.
- If you enforce DMARC: make sure your DMARC policy is not set to reject messages that pass SPF or DKIM.
