OTP & transactional email, delivered on time.
Connect your domain, call our API, and send one-time passcodes, receipts, and account emails with high deliverability — without running your own mail infrastructure.

Everything to ship email, minus the operations
One account, one API, two email types your product actually needs: time-sensitive OTPs and everyday transactional messages.
OTP delivery
Send one-time passcodes for login, signup, and payment confirmation with priority routing built for speed.
Transactional email
Receipts, password resets, welcome emails, and account notifications sent from your own verified domain.
Domain authentication
Add SPF, DKIM, and a tracking record in minutes. We verify ownership before your domain goes live.
Delivery insight
Track queued, sent, delivered, opened, and bounced events per message from your dashboard or webhooks.
Secure API keys
Every account gets a unique key issued only after email verification, so access stays scoped to you.
Built-in templates
Start from ready-made OTP and transactional templates, or send fully custom HTML from day one.
From signup to first send in four steps
No infrastructure to manage. Register, verify your inbox, connect your domain, and call the API.
Create an account
Register with your work email and set a password — takes under a minute.

Click the link we send you. Your account activates and your API key is issued.

Send your first email
Call the API or SMTP endpoint with your key and start delivering OTPs and receipts.
