What’s the appropriate toast after successful CRUD operation?

Assume we have a website or mobile app, that has e.g. a list of messages. User can add/delete/edit a message. After making an operation user receives a toast that operation has succeeded.

What's the most appropriate toast message for this scenario?

  1. <entity> was <action>
  2. <entity> has been <action>
  3. <entity> <action>
  4. <action>
  5. Something else

For example, if the <entity> is a "message" and performed <action> was "adding to favorites", the toast could say "Message has been added to favorites". I wonder if there's the conventional way of saying this according to some UI guides. Or I am just being meticulous.
