Powering transactional workflows for modern product teams
Everything you need to run transactional workflows
One reliable platform for the messages your product depends on — from the first verification email to the millionth webhook.
Workflow Automation
Design event-driven flows with a visual builder or code. Trigger messages the instant a user acts — no cron jobs, no glue code.
Notifications
Deliver in-app, email and push notifications from a single API with automatic routing, retries and per-channel fallbacks.
Email Automation
Transactional email with responsive templates, versioning and localization — verification, receipts, resets and alerts.
Analytics
Track delivery, opens, clicks and conversions in real time. Segment by event, template, region or user cohort.
API Integration
Clean REST and webhook APIs with SDKs for Node, Python, Go, Ruby and PHP. Send your first message in under five minutes.
User Management
Organizations, teams, roles and granular permissions. Invite collaborators and manage access with full control.
Secure Authentication
Built-in OTP, magic links and multi-factor flows. Ship account verification and password resets without reinventing security.
Audit Logs
Immutable, exportable logs of every message and admin action — searchable for compliance, forensics and support.
Cloud Infrastructure
Multi-region, redundant infrastructure with automatic failover. Your messages route through the fastest healthy path.
Scalability
Elastic throughput that absorbs spikes from a handful to millions of messages per minute — with zero configuration.
Monitoring
Live dashboards, uptime tracking and instant alerts. Know the moment a provider degrades — before your users do.
Data & Suppression
Automatic bounce and complaint handling with global suppression lists that protect your sender reputation.

Reliable messaging, engineered to last
Westgrove began in 2019 when a small group of infrastructure engineers grew tired of stitching together fragile scripts to send the messages their products couldn't live without. A single missed verification email could cost a customer; a delayed OTP could lock someone out.
So we built the platform we always wanted — one that treats every transactional message as mission-critical. Today Westgrove delivers billions of messages a year for thousands of teams, and we obsess over the details so you don't have to.
Our Mission
To make critical communication effortless and dependable for every product team on earth.
Our Vision
A world where no important message is ever lost, delayed or delivered to the wrong person.
Trust
Security and privacy are foundations, not features.
Reliability
We measure ourselves in nines and milliseconds.
Craft
Details compound. We sweat the small things.
Customers
Their uptime is our uptime. We answer fast.
Enterprise-grade security, by default
Your data and your users' trust are protected at every layer. Security isn't an add-on at Westgrove — it's the architecture.
SSL / TLS Everywhere
All traffic is encrypted in transit with TLS 1.3. Sending domains are protected with SPF, DKIM and DMARC.
Encryption at Rest
Data is encrypted at rest with AES-256. Secrets and API keys are stored in a hardened, isolated vault.
Strong Authentication
MFA, SSO and SAML for your team. OTP, magic links and passkeys for your users — all built in.
Resilient Infrastructure
Multi-region, redundant infrastructure with automatic failover, DDoS protection and 24/7 monitoring.
Privacy First
We're GDPR and CCPA aligned. You own your data; we never sell it, and we honor deletion requests promptly.
Role-Based Access
Granular RBAC lets you grant precise permissions per team member, with every action captured in audit logs.
Transactional-only sending policy
Westgrove is engineered around a single principle: we send only transactional email, triggered by authenticated user actions. Here is exactly how we keep sending clean, compliant and trusted.

"We switched to Westgrove after a competitor dropped our OTP delivery during a launch. Six months in, we've had zero missed verifications and our support tickets fell by a third."
