J2 Global Communications Inc. said Thursday it has acquired the RapidFax business of Easylink Services International, a Norcross, GA-based business-to-business e-commerce services provider.

Terms of the deal were not disclosed. Los Angeles-based J2 said the deal includes all RapidFax customers, the RapidFax trademark and other related assets. RapidFax provides online fax-to-email services for consumers. J2 also said that the financial impact of the purchase is “immaterial.”

In July, J2 acquired Ireland-based messaging services provider YAC Limited for an undisclosed sum.

Shares in J2 were down 8 cents to $22.28 in early trading Thursday on the Nasdaq. Shares in J 2 have slipped 32 percent since the company reported third-quarter earnings in early November that missed Wall Street’s expectations.
