Risu Mail
Send email. Skip the bill shock.
Free email API and SMTP for students and developers. Transactional mail, bulk campaigns, templates, and real-time analytics, under 100ms delivery, with a free tier built for India and campus builders. Live at risumail.risu.in.
// POST /v1/send { "to": "user@example.com", "template": "otp-login", "vars": { code: 482910 } }
Email infrastructure is either expensive (SendGrid-scale pricing) or clumsy (legacy SMTP, delayed analytics). Students and early startups need a free tier that is actually usable, and a migration path that does not rewrite their stack.
One mail platform: modern REST API, SMTP at smtp.risu.in, drag-and-drop templates, sequences, contact forms, and live delivery logs. Student benefits and a generous free plan for MVPs.
Everything you need to send at scale.
Powerful REST API
Send with one request. SDK-shaped responses and strict TypeScript types for developer workflows.
SMTP relay
Point any app at smtp.risu.in, with no API refactor required for legacy clients.
Templates & personalization
Drag-and-drop templates plus variables for brand-consistent transactional and marketing mail.
Sequences & forms
Drip campaigns on a schedule, plus embeddable contact forms with spam protection.
Real-time analytics
Opens, clicks, bounces and queue events with exportable logs, under 100ms delivery.
Student-first free tier
Practical free limits for hackathons and MVPs, with verification-based student quota upgrades.
