Email API for Agencies Managing Client Domains
Agencies and freelancers often manage email across many client sites, apps, and campaigns. NoticeAPI keeps those senders in one developer-first email API with multiple verified domains, delivery logs, suppressions, and consent-based broadcast tools.
curl -X POST https://www.noticeapi.com/api/v1/email/send \
-H "Authorization: Bearer ntc_xxxxxxxxxxxxxxxxxxxx" \
-H "Content-Type: application/json" \
-d '{
"from": "Client Support <[email protected]>",
"to": "[email protected]",
"subject": "Your project update",
"html": "<p>Your request has been received.</p>"
}'Many sending domains
Use plan-based domain limits for multiple client products, microsites, and app senders.
DNS and sender safety
Each production sender still uses verified DNS, suppressions, and the deliverability autopilot.
Client-visible evidence
Logs, timelines, and webhooks make it easier to show what sent, delivered, bounced, or was suppressed.
Transactional plus broadcasts
Send app notifications and consent-based product updates without buying a separate marketing tool for every client.
How it works
From test send to production traffic.
Add client domains
Create each sender domain and publish the DNS records with the client's DNS provider.
Use one API surface
Send through REST, SDK, or SMTP while keeping logs and suppressions in NoticeAPI.
Separate transactional and marketing intent
Use direct sends for app-triggered mail and broadcasts for consent-based audience updates.
Review delivery outcomes
Use logs, webhook events, and suppression state when clients ask what happened.
Trust
Agency scale without cold outreach positioning
NoticeAPI is for legitimate product email and consent-based broadcasts. It is not a cold outreach, purchased-list, CRM, or dedicated-IP product.

FAQ
Questions developers ask before switching email.
Can each client use a different sending domain?
Yes. Add and verify each sender domain, then send from approved addresses on those domains.
Is NoticeAPI for agency cold outreach?
No. Cold outreach, purchased lists, scraped lists, and CRM-style sales engagement are out of scope.
Do upgrades require DNS changes?
No. Existing verified domains stay configured when the account moves to a higher plan.
