Email to Webhook Conversion for Developers
MailWebhook converts inbound email into reliable webhook events your applications can consume in real time. Connect any mailbox, define routing rules, and receive deterministic JSON — without IMAP scripts or polling loops.
Everything you need to automate email workflows
Built for developers who need reliable email-to-webhook conversion without the complexity
Real-time Processing
Connect Gmail, Microsoft 365, or any IMAP mailbox. Get instant webhook delivery with push notifications or configurable polling intervals.
Deterministic JSON Schema
Transform emails into structured JSON with custom mappers. Extract exactly what you need with powerful filtering and transformation rules.
Secure & Reliable
HMAC signatures, automatic retries with exponential backoff, and replay protection. Your data stays secure with EU residency options.
Smart Routing
Create multiple routes per project with custom filters. Send different emails to different endpoints based on your conditions.
Event Inspector
Debug with confidence using our event inspector. View full request/response logs, replay events, and monitor delivery status.
Multiple Outputs
Deliver to Slack, Teams, Discord, or any webhook endpoint. One email can trigger multiple destinations simultaneously.
How it works
From mailbox to webhook in four simple steps
Connect Your Mailbox
Link Gmail, Microsoft 365, or any IMAP mailbox. Or use our hosted mailbox for instant setup.
Configure Filters
Set up routing rules with conditions. Filter by sender, subject, body content, or custom patterns.
Transform to JSON
Define your output schema. Extract headers, body, attachments, and metadata into structured JSON.
Deliver Webhooks
Receive reliable webhook deliveries with retries, HMAC signatures, and delivery confirmations.

}Common email to webhook use cases
Turn any inbound email workflow into an automated, event-driven pipeline
Support ticket automation
Route inbound support emails directly into your ticketing system as structured events. Filter by sender domain, subject pattern, or body content and deliver a clean JSON payload to your API without manual triage.
Order and invoice processing
Receive supplier invoices, order confirmations, and shipping notifications by email and convert them into webhook events your ERP or finance system can consume immediately — with attachment metadata included for document retrieval.
Vendor and partner notification handling
Process automated notifications from vendors, payment processors, and logistics partners that still send via email. Route each sender to the right internal endpoint without building or maintaining custom IMAP integrations.
System alert and monitoring pipelines
Forward infrastructure alerts, error digests, and monitoring notifications arriving by email into your observability stack or incident management system in real time, with retry guarantees and full delivery history.
Stop fighting with brittle scripts and expensive automation tools
IMAP scripts break. Zapier gets expensive. MailWebhook just works.

Frequently asked questions
What is email to webhook?
Email to webhook means converting an inbound email into an HTTP POST request sent to a URL your application controls. Instead of polling a mailbox, your system receives structured JSON automatically the moment a message arrives.
How does email to webhook work?
MailWebhook monitors your connected mailbox or hosted address, parses each incoming message, applies your routing rules, transforms the content into a deterministic JSON payload, and delivers it to your endpoint via HTTP POST — with automatic retries and HMAC signature verification included.
When should I use email to webhook instead of polling?
Use email to webhook when message latency matters, when inbox volume is growing beyond what a polling loop handles reliably, or when the workflow downstream expects event-driven input rather than scheduled batch processing. Webhooks also eliminate the server overhead of constant API polling.
What does a MailWebhook payload look like?
Each delivery is a JSON POST containing a schema identifier, event metadata, the normalized message (from, to, subject, date, text and HTML body), attachment descriptors, and raw headers. The structure is deterministic — the same input class always produces the same output shape.
Is email to webhook secure?
Yes. Every webhook delivery includes an HMAC signature header your endpoint can verify to confirm the request came from MailWebhook. Outbound delivery targets are restricted to public HTTPS endpoints, and all attachment retrieval requires authenticated pre-signed URLs.
Which email providers does MailWebhook support?
MailWebhook connects to Gmail, Microsoft 365, and any IMAP mailbox. You can also use a MailWebhook-hosted address for instant setup without configuring an existing provider.
