Selecting target audiences for marketing campaigns

A system for selecting audience members for a marketing campaign, comprising:

• a memory;
• one or more processors;
• and
• an audience selection system executable by the one or more processors to
• access a list of potential audience members, wherein each potential audience member is associated with a corresponding feature vector comprising corresponding values of one or more features,
• identify, within the list, a first group and a second group of audience members, wherein there is no overlap between the first and second groups,
• cause initiation of the marketing campaign with the first group of audience members, without including the second group in the marketing campaign,
• identify (i) a first subset of the first group of audience members that have responded positively to the marketing campaign, and (ii) a second subset of the first group of audience members that have not yet responded positively to the marketing campaign,
• identify a first audience member in the second group of audience members, such that a similarity strength between the first audience member and one or more audience members within the first subset is higher than a similarity strength between the first audience member and one or more audience members within the second subset, the similarity strength based on a feature vector associated with the first audience member,
• update the first group to include the first audience member, and
• cause to continue the marketing campaign with the updated first group.

A computer program product including one or more non-transitory machine-readable mediums encoded with instructions that when executed by one or more processors cause a process to be carried out for selecting audiences for a marketing campaign, the process comprising:

• accessing a list of potential audience members;
• identifying, within the list, (i) a first group of target audience members for the marketing campaign, and (ii) a second group of non-targeted audience members;
• identifying (i) a first subset of the first group of audience members who have responded positively so far to the marketing campaign, and (ii) a second subset of the first group of audience members who have not yet responded positively so far to the marketing campaign;
• determining that a first similarity strength among audience members in the first subset is less than a second similarity strength between audience members in the first subset and audience members in the second subset;
• and
• in response to determining that the first similarity strength is less than the second similarity strength, updating the first group to include an audience member from the second group, wherein the marketing campaign is to target the updated first group of audience members.
