Dewmail review
A focused SMTP-to-webhook bridge for developers building self-hosted email pipelines.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Dewmail is an open-source email parsing microservice for developers who need to add an email frontend to an existing API. It receives email for a configured domain, parses the message, and sends a JSON-encoded HTTP POST request to an application API. Its scope is focused: SMTP receipt, recipient-based routing, and HTTP delivery rather than a broad email automation suite. Teams that already operate an API and want email to enter an existing application workflow are the clearest fit.
The central integration model is straightforward. Dewmail receives mail through a configured domain, then sends JSON requests to recipient-address paths, giving applications a predictable way to distinguish incoming addresses or routes. Optional HTTPS delivery adds a transport-security configuration, while optional SPF validation and enforcement provide additional control over accepted messages. The product is positioned around API access and webhook delivery, so it suits custom application stacks more naturally than teams seeking prebuilt connectors or a large platform ecosystem.
Deployment is the main operational consideration. Hosted or self-managed use requires DNS MX-record setup, and self-hosting places the service on the user's own hardware under the MIT License. That makes Dewmail a practical choice for teams comfortable managing mail routing and API infrastructure. It is less suitable for buyers who want guided onboarding, structured extraction of fields, attachment workflows, or a catalog of integrations. Choose it when a narrow SMTP-to-webhook bridge is enough; consider another tool when email parsing needs extend beyond routing messages into an API.
