Some years ago, I co-founded a startup that would run workflows when email messages arrived, any email from any source was parsed and it would trigger "actions" that could include notifications - this sounds like a good use case for it! You don't need the service to expose an api to listen in, since most services end up sending email as last fallback.
Thank you for you feedback!
Do you still run that startup?
With Cozy Watch, I use the GitHub API, never thought about using emails as triggers.
I’ve actually got GitHub emails disabled, they can get pretty spammy.
