(1) The notice of appeal shall specify by name all appellants and all appellees (“et al.” and “etc.” are not proper designation of parties) and shall identify the judgment, order or part thereof appealed from. It shall contain a certificate that a copy of the notice has been served upon all opposing counsel, or parties, if unrepresented, at their last known address.

(2) When the notice of appeal is filed, the clerk shall serve notice of its filing by mailing a copy showing the date filed and a copy of the official docket sheet to the clerk of the appellate court and to the attorney of record of each party or to the party, if unrepresented. The clerk shall note in the civil docket the names of the parties mailed the copies, with the date of mailing. Failure of the clerk to comply with this rule does not affect the validity of the appeal.
