Not sure I understand, can you please describe in detail.
Please check dataconnector’s events. You can attach your own custom function to delete/update some events or send emails in your case. As an example you can check events_rec.php file in the package.
There could be different answers depending on what exactly you are doing.
You can use the same connectors events to delete outdated events every time page rendered, for example.
Kind regards,
Ilya
