Sending domains
Email API for Multiple Sending Domains
NoticeAPI is built for builders who run more than one product, workspace, or client sender. Add verified domains, send from any approved address on those domains, and keep REST, SDK, SMTP, webhooks, and suppressions on the same API.
curl -X POST https://www.noticeapi.com/api/domains \
-H "Cookie: noticeapi_session=..." \
-H "Content-Type: application/json" \
-d '{ "domain": "send.acme.com" }'Plan-based domain counts
Free includes 1 domain, Launch includes 15, Build includes 50, and Grow includes 2,000.
DNS verification
NoticeAPI generates ownership, SPF, DKIM, and DMARC records so production senders are authenticated.
Sender identities on first use
Once a domain is verified, local parts and display names can be used naturally in API sends.
No DNS redo on upgrade
Capacity expands with the account; upgrades do not require rebuilding sender DNS for existing domains.
How it works
From test send to production traffic.
Add the domain
Create a sending domain in the portal and copy the generated DNS records.
Publish DNS
Add the ownership, SPF, DKIM, and recommended DMARC records at your DNS provider.
Verify readiness
NoticeAPI checks each record and marks the domain verified when production sending is allowed.
Send for each product
Use the same API key and endpoints while sending from each verified product or client domain.
Trust
Many domains, one safety model
Additional domains do not bypass sender checks. Each production sender still uses domain verification, ramp limits, suppressions, logs, and the deliverability autopilot.
Implementation links
Build with the shipped docs.
FAQ
Questions developers ask before switching email.
How many domains can I add?
Free includes 1, Launch includes 15, Build includes 50, and Grow includes 2,000 verified sending domains.
Do I need to redo DNS when I upgrade?
No. Existing verified domains stay configured. Higher plans expand limits and quota without changing the DNS you already published.
Can each domain send broadcasts and transactional email?
Yes, if the domain is verified and the send respects the right path: transactional messages through send or SMTP, consent-based marketing through broadcasts and automations.
Start free. Send production after your domain is ready.
Free includes 3,000 production emails per month, a 100/day production cap, and one verified sending domain.
