Item 1. Security and Issuer

The class of equity securities to which this statement on Schedule 13D (the "Statement") relates is the common stock, par value $0.01 per share (the "Common Stock"), of Juno Online Services, Inc., a Delaware Corporation (the "Issuer"), with its principal executive offices located at 1540 Broadway, New York, NY 10036.

Item 2. Identity and Background

This Statement is being filed by NetZero, Inc., a Delaware corporation ("NetZero"). The address of the principal executive office of NetZero is 2555 Townsgate Road, Westlake Village, California 91361.

Information regarding the directors and executive officers of NetZero is set forth on Schedule I attached hereto. All of the directors and executive officers of NetZero are U.S. citizens.

During the last five years, to the knowledge of NetZero, no person named on Schedule I has been (a) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (b) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding is or was subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration

On June 7, 2001, NetZero, the Issuer, United Online, Inc., a Delaware corporation ("United Online"), NZ Acquisition Corp. and JO Acquisition Corp. entered into an Agreement and Plan of Merger (the "Merger Agreement"), pursuant to which NetZero and the Issuer will effect a business combination, upon the terms and subject to the conditions set forth in the Merger Agreement (the "Mergers") and resulting in each of NetZero and the Issuer becoming a wholly owned subsidiary of United Online.

In connection with the Merger Agreement, NetZero entered into voting agreements, dated as of June 7, 2001 (collectively, the "Voting Agreements"), with each of Charles Ardai, President and Chief Executive Officer of the Issuer, Harshan Bhangdia, Senior Vice President and Chief Financial Officer of the Issuer, Richard Buchband, Senior Vice President and General Counsel of the Issuer, Louis Salkind, a director of the Issuer and David E. Shaw, Chairman of the Board of Directors of the Issuer (collectively, the "Stockholders"). Pursuant to the Voting Agreements, each of the Stockholders has agreed that from June 7, 2001 until the termination of the Voting Agreements, such Stockholder will vote or cause to be voted the shares of Common Stock over which such Stockholder has voting power to adopt the Merger Agreement (as more fully described in Item 6).

Item 4. Purpose of Transaction

The purpose of entering into the Voting Agreements was to acquire beneficial ownership of the Stockholders' shares of Common Stock in order to facilitate the adoption of the Merger Agreement by the Stockholders.

Other than as described above, NetZero currently has no plans or proposals which relate to, or may result in, any of the matters listed in Items 4(a)-(j) of Schedule 13D (although NetZero reserves the right to develop such plans).

Item 5. Interest in Securities of the Issuer

(a)-(b) NetZero beneficially owns and has the shared power to vote 13,410,285 shares of Common Stock, representing 32.13% of the outstanding shares of the Issuer. The calculation of the foregoing percentage is based on the number of shares of Common Stock disclosed to NetZero by the Issuer as outstanding as of June 7, 2001. Except as set forth herein, to the knowledge of NetZero, no director or executive officer of NetZero beneficially owns any other shares of the Issuer.

(c) There have been no transactions by NetZero in securities of the Issuer during the past sixty days. To the knowledge of NetZero, there have been no transactions by any director or executive officer of NetZero in securities of the Issuer during the past sixty days.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer

In connection with the Merger Agreement, David E. Shaw and certain other entities (collectively, the "Parties") executed a letter to NetZero agreeing to amend the registration rights agreement under which the Parties had rights to cause the Issuer (and, after closing of the Mergers, United Online) to register under the Securities Act of 1933 (the "Securities Act") the Parties' Common Stock in the Issuer (or, after closing of the Mergers, the Parties' common stock in United Online) such that the current persons or entities who have rights to require NetZero to register their common stock in NetZero under the Securities Act shall be able to have such rights pari passu with the Parties' registration rights.

Pursuant to the Voting Agreements, each of the Stockholders agreed that from June 7, 2001 until the termination of the Voting Agreements, at every meeting of the stockholders of the Issuer called with respect to any of the following, and at every adjournment or postponement thereof, and on every action or approval by written consent of the stockholders of the Issuer with respect to any of the following, such Stockholder will vote or cause to be voted such Stockholder's shares of Common Stock (x) in favor of (i) adoption of the Merger Agreement (ii) waiving any notice that may have been or may be required relating thereto and (iii) any matter that would reasonably be expected to facilitate the Mergers and (y) against any matter that would reasonably be expected to hinder, impede, prevent or delay the consummation of the Mergers. Additionally, such Stockholder may not enter into any agreement or understanding with any person to vote or give instructions inconsistent with clause "(x)" or "(y)" of the preceding sentence. In connection with the Voting Agreements, the Stockholders also have granted proxies to certain officers of NetZero to vote their Common Stock in the manner described above.

The descriptions of the Merger Agreement and the Voting Agreements contained in this Statement are qualified in their entirety by reference to such agreements, a copy or form of which appear as Exhibits 1 and 2 hereto, respectively.
