How it works
Integrate with a REST call or SMTP credentials — then monitor every message from the dashboard or webhooks.
Step 01
Add a sender domain, verify DNS (SPF, DKIM, DMARC), and generate API or SMTP credentials in minutes.
Step 02
POST to /api/send or point your app at our SMTP relay. Use templates for transactional mail or lists for campaigns.
Step 03
Delivery, bounces, opens, and clicks logged in real time. Wire webhooks into your product for instant reactions.
Customers
Leaders at Iksha Global, The HR Page, N3 News, Iksha Jobs, and MVSS Adhiratha use Mailmatic for product email and notifications.
We moved OTP and account emails to Mailmatic in an afternoon. DNS verification was straightforward, and having delivery logs in one place made debugging failed sends much faster than our old setup.
Reliable delivery for HR workflows and candidate notifications — exactly what we needed without juggling multiple tools.
Breaking news alerts and subscriber updates go out through one API. The dashboard gives us confidence every send is tracked.
Job alerts and application confirmations are core to our product. Mailmatic’s API fit cleanly into our existing Node stack.
Multi-domain sending from a single dashboard simplified how we manage client sites — each brand keeps its own keys and reputation.
Reliable delivery, full logs, and campaigns — priced for teams who need more than a bare SMTP pipe.

Why not the cheapest credit-only API? Ultra-low per-email pricing usually means SMTP-only pipes with minimal logs, support, or campaign tooling. Mailmatic is for teams that care about deliverability, observability, and running email as a product surface — not only minimizing rupees per message.
