Systems and methods for updating email addresses based on email generation patterns

A system comprising:

• one or more hardware processors configured by machine-readable instructions to:
• maintain a plurality of member node profiles corresponding to a plurality of unique member entities, each member node profile including a plurality of field-value pairs;
• access a plurality of electronic activities transmitted or received via electronic accounts associated with one or more data source providers, the plurality of electronic activities used to update the plurality of member node profiles;
• determine, for a group entity, a plurality of member node profiles linked to a group node profile of the group entity;
• identify, for each member node profile of the plurality of member node profiles, a first field-value pair of the member node profile corresponding to an electronic account identifier of the member node profile, the electronic account identifier identifying an address via which electronic activities are transmitted from or received by the electronic account of the member node profile;
• determine, for each member node profile, a correlation between the first field-value pair corresponding to the electronic account identifier of the member node profile, a second field-value pair corresponding to a first name of the member node profile and a third field-value pair corresponding to a last name of the member node profile;
• determine, based on the determined correlation, an electronic account identifier pattern used by the group node to generate electronic account identifiers;
• and
• store, in one or more data structures, an association between the group node and the electronic account identifier pattern.

A non-transient computer-readable storage medium having instructions embodied thereon, the instructions being executable by one or more processors to perform a method comprising:

• maintaining a plurality of member node profiles corresponding to a plurality of unique member entities, each member node profile including a plurality of field-value pairs;
• accessing a plurality of electronic activities transmitted or received via electronic accounts associated with one or more data source providers, the plurality of electronic activities used to update the plurality of member node profiles;
• determining, for a group entity, a plurality of member node profiles linked to a group node profile of the group entity;
• identifying, for each member node profile of the plurality of member node profiles, a first field-value pair of the member node profile corresponding to an electronic account identifier of the member node profile, the electronic account identifier identifying an address via which electronic activities are transmitted from or received by the electronic account of the member node profile;
• determining, for each member node profile, a correlation between the first field-value pair corresponding to the electronic account identifier of the member node profile, a second field-value pair corresponding to a first name of the member node profile and a third field-value pair corresponding to a last name of the member node profile;
• determining, based on the determined correlation, an electronic account identifier pattern used by the group node to generate electronic account identifiers;
• and
• storing, in one or more data structures, an association between the group node and the electronic account identifier pattern.
