Delivery Machine vs InboxMail
Both stand on email forwarding services. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan API
Pick Delivery Machine if you want to manage custom-domain forwarding from a command line, with a free tier for small setups and paid plans for more domains and volume. Look elsewhere if you need a web UI, since the product is managed through its CLI and says no web UI is required.
