Abstract: A method for establishing credentials for securing text message communications. The method includes receiving, at a text messaging hub executing at a server device, a text message from a user, the text message being directed to a service number and including (1) a user number and (2) a request to establish a secure credential for communicating with a text messaging application. The method also includes transmitting, by the text messaging hub executing at the server device, an initiation message to the user, the initiation message includes a user-specific system number to which the user is to direct future text messages.

Abstract: Systems and method for generating contact suggestions are provided in which one or more suggested contacts are identified from a set of contacts associated with a user. This includes identifying in historical communications in a user account associated with the user, one or more groups of contacts. Scores are generated for contacts in the identified groups of contacts, including generating a contact score for a respective contact by accumulating score contributions for a plurality of the identified groups of contacts that include the respective contact. One or more suggested contacts are identified in accordance with the generated scores. A contact suggestion is sent based on the suggested contacts for display to the user. The contact suggestion includes a suggested contact with a generated score that is above a predefined threshold.

Abstract: Methods, systems, and apparatus, including computer programs for identifying, using historical interactions associated with a first user, contact groups, where the first user is associated with each contact group, are provided. A score, with respect to a second user, is calculated for each contact group based on an amount of interaction between the second user and the respective contact group, thereby deriving a plurality of scores. A first contact group is determined. The first contact group has a first score in the plurality of scores that satisfies a predetermined threshold. A contact group suggestion is generated, responsive to the determining, that comprises an invitation to add the second user to the first contact group. The first user is notified of the contact group suggestion.

Abstract: In some implementations, a method includes, at a computing device, identifying a first recipient of a draft electronic communication prepared by a user. A is score is obtained for a second recipient using respective messages in a plurality of historical messages in a user account associated with the user. The second recipient is a sender or receiver of the respective messages. There is suggested to a user, second recipient for the draft electronic communication in accordance with a condition that both the first recipient and the second recipient shared a single electronic communication and the score for the second recipient satisfies a predefined score threshold. The single electronic communication was communicated at a time prior to identifying the first recipient.

Abstract: Systems and methods for generating contact suggestions are provided. In some implementations, a method includes, at a computing device, identifying a first recipient of a draft electronic communication; and suggesting, to a user, a second recipient for the draft electronic communication in accordance with a condition that both the first recipient and the second recipient shared a single electronic communication. The single electronic communication was communicated at a time prior to identifying the first recipient. In some implementations, the method optionally includes, suggesting, to the user, a removal of a third recipient of the draft electronic communication. In other implementations, the method optionally includes, suggesting, to the user, a replacement of a fourth recipient of the draft electronic communication.

Abstract: A computer system having one or more processors and memory receives seed data comprising contacts specified for a draft communication, selects at least a subset of the seed data as a seed set of contacts, and identifies one or more suggested contacts based on the seed set. Identifying the suggested contacts includes: identifying in historical communications in a user account, groups of contacts that include one or more of the contacts in the seed set; generating scores for contacts in the identified groups of contacts, including generating a contact score for a respective contact by accumulating score contributions for a plurality of the identified groups of contacts that include the respective contact; and identifying the one or more suggested contacts in accordance with the generated scores. The computer system sends a contact suggestion based on the suggested contacts for display in conjunction with the draft communication.
