## What it is
Griddler is a Rails engine that provides an HTTP endpoint for email delivery services (SendGrid, Cloudmailin, Postmark, Mandrill, Mailgun) that convert incoming emails into POST requests. It parses those requests into a simple email object and hands it to a user-defined processor class. It was deprecated in June 2024 in favor of Rails' built-in ActionMailbox.

## Use cases
- receive incoming emails in a Rails app
- parse emails forwarded by SendGrid or Postmark webhooks
- build reply-by-email features like posting comments via email
- extract attachments and bodies from inbound email POSTs
- strip reply text below a reply delimiter
- route email service webhooks to application logic

## When to choose
- maintaining a legacy Rails app already using Griddler
- on an old Rails version that predates ActionMailbox

## When to avoid
- starting a new Rails project (use ActionMailbox instead)
- you need ongoing support or updates
- your Rails version includes ActionMailbox

## Facets
- artifact type: library
- maturity: abandoned
- function: email, parser, middleware
- domain: web-development, email, backend
- platform: ruby
- tags: rails-engine, incoming-email, deprecated, sendgrid, postmark, email-parsing, web-server
