What you get with MailsSetu
Built for developers who want to ship communications fast and correctly.
One endpoint to send email
POST /v1/emails with from, to, subject, and html. That's it. MailsSetu handles delivery, bounce processing, suppression, and events automatically.
INR pricing — no USD required
Built for Indian teams. Pay in rupees via UPI or cards. GST invoices generated automatically. No currency conversion, no international card requirement.
SMS and OTP in the same account
No need to maintain separate vendors. MailsSetu handles transactional email, SMS, and OTP verification — unified billing, unified logs, unified API key.
Sandbox from day one
Your ms_test_ key works immediately. Test sends, webhooks, OTP flows, and template rendering without any domain configuration or production credentials.
Batch sends and scheduled delivery
Send up to 100 emails in a single API call. Schedule emails for the future and cancel them if needed. Idempotency keys make retries safe.
Inbound email routing
Receive emails and route them to your webhook. Handle support replies, form submissions, or automated workflows — all from the same MailsSetu account.
Simple INR pricing
Flat-rate monthly plans. No per-email surprise charges above quota.
SMS credits and top-up email credits available separately. GST applied on all invoices. UPI · Debit/credit cards · Net banking accepted.
India-first. Not India-as-an-afterthought.
MailsSetu is purpose-built for Indian developers and startups — INR billing, GST invoices, India-based support, and managed delivery infrastructure for low-latency transactional email.
