It's already built into JMAP.  From RFC8621:

   o  preview: "String" (immutable; server-set)

      A plaintext fragment of the message body.  This is intended to be
      shown as a preview line when listing messages in the mail store
      and may be truncated when shown.  The server may choose which part
      of the message to include in the preview; skipping quoted sections
      and salutations and collapsing white space can result in a more
      useful preview.

      This MUST NOT be more than 256 characters in length.

      As this is derived from the message content by the server, and the
      algorithm for doing so could change over time, fetching this for
      an Email a second time MAY return a different result.  However,
      the previous value is not considered incorrect, and the change
      SHOULD NOT cause the Email object to be considered as changed by
      the server.
