For indie developers
Email API for Indie Developers Running Multiple Products
If you run several small products, every app eventually needs resets, receipts, alerts, updates, and a sender domain. NoticeAPI gives indie developers one email API for those product emails instead of a new email account and marketing bill for every side project.
curl -X POST https://www.noticeapi.com/api/v1/email/send \
-H "Authorization: Bearer ntc_xxxxxxxxxxxxxxxxxxxx" \
-H "Content-Type: application/json" \
-d '{
"from": "Tiny App <[email protected]>",
"to": "[email protected]",
"subject": "Welcome to Tiny App",
"html": "<p>Your account is ready.</p>"
}'Free simulator testing
Build reset, receipt, bounce, and webhook paths before sending real email.
Multiple project domains
Launch includes 15 sending domains, useful for builders with several products or experiments.
REST, SDK, and SMTP
Use the send API for new apps, the Node SDK for TypeScript, or SMTP for older projects.
Safety without ops work
Suppressions, unsubscribe handling, logs, and autopilot reduce the email chores a solo builder has to remember.
How it works
From test send to production traffic.
Start in the sandbox
Use simulator recipients to test product email flows without quota or reputation risk.
Verify each product domain
Add DNS for the products that should send production email.
Reuse templates and patterns
Keep common reset, receipt, welcome, and update messages in NoticeAPI templates.
Send updates with consent
Use audiences and broadcasts for product updates, newsletters, and launch notes only when recipients opted in.
Trust
One product-email layer for several small bets
NoticeAPI keeps indie email practical: transactional sends, consent-based broadcasts, and testing tools in one platform without turning it into CRM or outreach software.
Implementation links
Build with the shipped docs.
FAQ
Questions developers ask before switching email.
Can I use one account for several products?
Yes. Add each product's sending domain as long as it fits your plan's domain limit.
Do I need a paid plan to test?
No. The free workspace includes simulator testing. Starter is the first plan for production email from a verified domain.
Can I email users of one side project about another project?
Only with appropriate consent. Use audiences and unsubscribe handling for marketing or product-update sends.
Test free. Send production from $5.
The free workspace covers simulator testing. Starter includes 3,000 production emails per month, a 100/day production cap, and one verified sending domain.
