Inbound
Processing
Receive and parse incoming emails via webhooks. Build support systems, email-to-task workflows, and automated responses on top of real email.
Parsed and ready
as JSON
No MIME parsing, no regex on raw email. Every inbound email arrives at your webhook as a clean, structured JSON object.
{ "from": "customer@company.com", "to": "support@yourdomain.com", "subject": "Need help with my account", "text": "Hi, I can't log in to my dashboard...", "html": "<p>Hi, I can't log in to my dashboard...</p>", "headers": { "message-id": "<abc123@company.com>", "date": "Thu, 13 Feb 2025 10:30:00 +0000" }, "attachments": [ { "filename": "screenshot.png", "contentType": "image/png", "size": 24531 } ]}Email in,
webhook out
Configure MX records
Point your domain's MX records to Posthawk's SMTP server. One DNS change is all you need.
Emails are received
The built-in SMTP server accepts incoming emails, parses headers, body, and attachments.
Webhook fires
A structured JSON payload is sent to your endpoint with sender, subject, body text, HTML, and attachments.
Webhook Delivery
Every inbound email triggers a webhook to your endpoint with the full parsed email as a structured JSON payload.
Attachment Parsing
Attachments are extracted, base64-encoded, and included in the webhook payload. No manual MIME parsing needed.
Spam Filtering
Built-in SPF and DKIM verification to reject spoofed senders. Only legitimate email reaches your webhook.
Per-Domain Webhooks
Each receiving domain gets its own webhook URL. Add support.yourapp.com and billing.yourapp.com as separate domains to fan inbound mail out to different systems.
Build on top
of real email
