Amazon.com Inc. signed a three-year agreement with Poste Italiane SpA that will help the U.S. online retail giant distribute its products in Italy, the postal services provider said in a June 13 news release.

The transaction, which can be extended two years, aims to accelerate e-commerce growth in the country.

Although financial details of the collaboration were not disclosed, the agreement is in line with Poste's financial strategic plan Deliver 2022, under which the mail operator targets parcel revenue of €1.2 billion by 2022.

As part of the deal, the companies will include service improvements such as deliveries until 7:45 p.m. in Italy and on weekends.

The partnership will utilize the Italian company's mail and parcel joint delivery model rolled out in April; its express courier unit, SDA; its airline subsidiary, Mistral Air; and more than 30,000 of its postal employees.
