Speed matters
A verification code that shows up after the user retries, refreshes, or abandons the flow is already too late.
Transactional Email Use Case
OTP emails only work when they arrive quickly and make the next step obvious. Leadpush helps teams deliver one-time codes for verification and sign-in with visibility into every time-sensitive send.
Why This Message Matters
Verification code flows sit right in the path of sign-in, step-up authentication, and account confirmation. Late or unclear messages create drop-off fast.
A verification code that shows up after the user retries, refreshes, or abandons the flow is already too late.
OTP emails should make the code, expiration window, and next action obvious at a glance.
Teams need predictable delivery behavior when authentication traffic spikes or user verification flows change.
Common Scenarios
One-time passcodes usually show up inside more than one authentication flow. These are the most common patterns teams need to support.
Send one-time codes during passwordless sign-in or email-based login verification flows.
Require a verification code before a sensitive action like changing a password or updating billing details.
Confirm account ownership with short-lived codes during signup, onboarding, or security review flows.
Why Leadpush
Leadpush gives teams one place to send time-sensitive codes, watch delivery behavior, and keep verification traffic on reliable sender infrastructure.
Add OTP delivery through an SDK, API, or SMTP path that already fits the way your auth flows send email today.
Watch send events and callbacks so teams can troubleshoot late or missing verification messages with real message-level data.
Keep verification traffic on sender identities and routing rules that reflect how critical authentication flows actually are.
