Yeap it is. There's a "Last Modified Time" field you can use, and you can add a formula field that can calculate how long it's been since it was updated with `DATETIME_DIFF()` and `NOW()`.
After that, you'll just need to use `IF()` to set up how long is too long, and output something like "Send email" once it's too long.
You'd then have an automation that'd trigger whenever a record had "Send email" in the previously mentioned field
