Hey Ian,
Thanks for reaching out to us and for your interest in our products!
Unfortunately our calendar doesn’t come packed with such notifications. The only messages our plugin sends are related to tickets purchases/RSVPs. I guess this is something that could be achieved with some custom code, but definitively not a feature of our product right now.
You are welcome to submit this feature request to The Events Calendar user voice page, where we gather feedback from our community regarding upcoming features.
Please let me know if I can help you with anything else,
Best,
Nico
