Transactional only Account, order, payment & security email

Transactional email infrastructure for modern marketplaces.

ClientReach helps online marketplaces reliably deliver account, order, payment, security, and other transaction-triggered emails at scale.

Built for transactional communication — not marketing campaigns. Every message is triggered by something a user actually did on your platform.

Workload

Built for high-volume transactional workloads

Marketplace platforms can generate hundreds of thousands of transactional events every day. ClientReach is designed around predictable, event-driven communication so critical messages can be processed efficiently as marketplace activity grows.

Expected transactional volume
Hundreds of thousands of messages per day

A planning range for marketplace workloads, not a reported customer figure. Volume varies with order activity, account growth, and seasonal peaks.

What we send

Triggered by a user's own action or account activity. Expected, time-sensitive, one recipient.

How it works

From marketplace event to inbox, in four steps.

Your application stays the source of truth. ClientReach receives the event, renders the right template, and handles delivery and tracking.

  1. 01

    Event

    A marketplace action occurs — a buyer checks out, a seller ships, a user resets a password.

    order.confirmed
  2. 02

    API

    The marketplace sends a transactional event through ClientReach.

    POST /v1/messages
  3. 03

    Processing

    ClientReach validates and processes the message, then renders the template.

    status: processing
  4. 04

    Delivery

    The transactional email is delivered to the intended recipient.

Platform

The parts of email your application shouldn't have to own.

ClientReach covers sending, templating, monitoring, and authentication workflows for application-triggered messages.

Transactional API

Simple API infrastructure for application-triggered messages, with idempotency keys and clear response codes.

Event-Based Delivery

Trigger messages from real marketplace events and map each event type to the template it needs.

Delivery Monitoring

Track processing, delivery, failures, and system status for every message you send.

Template Management

Manage consistent transactional email templates with versioning and variables for order, account, and payment data.

Security & Authentication

Support secure account and authentication workflows: verification codes, password resets, and sign-in alerts.

Scalable Infrastructure

Designed for marketplace workloads that can grow significantly over time, including seasonal and promotional-period peaks in order volume.

Reliability

Built around the messages your marketplace depends on.

Transactional emails often carry information people expect within moments of acting: a verification code, a receipt, a sign-in alert. When they're late or missing, users notice — and support tickets follow.

01

Predictable

Event-driven delivery workflows. The same event always follows the same path, so behavior is easy to reason about and test.

02

Observable

Clear visibility into message processing and delivery activity, from API request to the recipient's mail server response.

03

Scalable

Infrastructure designed for growing transaction volume, so a busy sales weekend doesn't delay a password reset.

Transactional traffic is kept separate from any promotional sending by design — ClientReach doesn't carry marketing mail, so your critical messages don't share a reputation with campaigns.

Security

Security is part of the infrastructure.

Transactional email often includes account access links, verification codes, and payment details. The platform is built with that in mind.

  • HTTPS/TLSEncrypted API traffic and TLS for mail transport where supported.
  • AuthenticationAuthenticated access to the dashboard and API.
  • API credential managementScoped keys you can create, rotate, and revoke.
  • Access controlsRole-based permissions for your team.
  • Event loggingA record of messages, key usage, and configuration changes.
  • Domain verificationSPF, DKIM, and DMARC checks before sending.
  • Secure transactional workflowsShort-lived links and codes for resets and verification.
