Sending EMails to a Data Set to create new rows, attachments or comments

Esp. for working with action lists or issue tickets, it is convenient to create some data objects (Text or Attachments) by sending an email to the corresponding data set.
There are some ways I can imagine:
1st: create a new row with email text data and attachment, adding some default initial values.
2nd: creating a comment to an existing row.

Is there something like this planned or already available.

I am not sure I understand your question completely.

So here just some general comments: SeaTable Enterprise comes with automations. An automation executes one or multiple actions based on a set of conditions (aka rules). This are the available actions:
Logically, you can also create a cascade of automations, meaning that one automation does something that triggers another automation. Example: One automation creates a new record, another automation does something with the newly created record.

Comments are possible, but you cannot work with them in an easy fashion. You cannot trigger an automation based on a comment and you cannot use automations to add a comment.
