The Future Of
Email Infrastructure
Send, schedule, and receive emails with a simple API. Self-host for free or use our managed cloud.
To start sending emails
Send, schedule
& receive
Transactional emails, scheduled delivery, inbound
webhooks, and React templates — all self-hosted.
Everything you need
for email infrastructure
Transactional Email
Send emails via a simple REST API powered by AWS SES with high deliverability out of the box.
Scheduled Sending
Schedule emails for future delivery and cancel or modify them anytime before they are sent.
Inbound Processing
Receive and process incoming emails via webhooks with full attachment and header parsing.
Email Templates
Create and manage reusable templates with dynamic variables built on top of React Email.
Team Workspaces
Collaborate with role-based access control to invite team members and manage permissions.
Self-Hostable
Deploy on your own infrastructure with Docker for full control over your data and email flow.
Three steps to
start sending
Connect your AWS SES
Add your SES credentials in the dashboard. Posthawk handles the rest — SPF, DKIM, and DMARC configuration guides included.
Send via REST API
A single POST request to send transactional emails. Schedule for later, use templates, or send raw HTML.
Receive via webhooks
Configure inbound email processing. Posthawk parses incoming mail and forwards structured data to your webhook endpoint.
curl -X POST https://api.posthawk.dev/v1/send \ -H "Authorization: Bearer ck_live_..." \ -H "Content-Type: application/json" \ -d '{ "to": "user@example.com", "subject": "Welcome aboard!", "html": "<h1>Hello {{name}}</h1>", "variables": { "name": "Alex" }, "scheduledAt": "2025-02-15T09:00:00Z" }'Simple, transparent
