Ability for users to get email alerts if new post title contains a keyword?

Ability for users to get email alerts if new post title contains a keyword?

We use custom post types to publish certain news/posts. Can this plugin allow users to be notified by email when a new post title contains a keyword they are looking for?

For example, we publish all types of business tips/news. But maybe user wants to be notified by email if any new posts containing the word “Tesla” in the post title.

I would gladly pay for such a feature if it does not yet exist.

Would anyone else?

Thank you!
