How to Turn Incoming Emails into JSON Webhooks (Without Running an SMTP Server)

Description and use

Applications that need to react to incoming emails can avoid running an SMTP server. SMTP2Hook receives mail, converts it to a JSON payload, and posts it to your webhook, simplifying architecture and eliminating complex MX and MIME handling.

Problem

Implementing email reception in an application requires complex SMTP infrastructure, DNS, MIME parsing, retries, and maintenance, which is burdensome for simple use cases such as ticket creation or automation triggers.

Outcome

The application can process incoming emails via a simple HTTP POST, avoiding the complexity of running an SMTP server and handling email parsing.

Workflow

• 1. Create an account with an inbound‑email service (e.g., SMTP2Hook).
• 2. Create an email endpoint and obtain the service’s SMTP address.
• 3. Configure the service to POST to the application’s webhook URL.
• 4. Send an email to the service’s SMTP address.
• 5. The service parses the email, constructs a JSON payload, and POSTs it to the webhook.
• 6. The application receives the JSON, validates the event type, extracts needed fields, and triggers downstream logic.

Evidence

Sending email is relatively straightforward. Receiving it is another matter.

Instead of having your application receive SMTP traffic, use a service that accepts the email and forwards it to your HTTPS endpoint as JSON.
