The main inspiration for astroid is the sup mail user agent. sup provided inspiration for notmuch which is a mail indexer. astroid is using notmuch as a backend.

Some parts of the user interface and layout have been copied from or has been inspired by the Geary mail client. Also, some inspiration and code stems from ner, another notmuch email client.
