What this service covers

Append contact, company and specialized fields.

Projects can focus on one missing field or a broader set of attributes, depending on how the existing records will be used.

01

Email appending

Add business email information to existing person or company records where a reliable match is available.

02

Phone appending

Add company phone, business phone or direct-dial fields where available and appropriate to the record.

03

Firmographic appending

Add company size, revenue band, industry, company domain, headquarters and other business attributes.

04

Digital profile appending

Add business URLs and professional or social profile fields where they are useful to the project.

05

Classification appending

Add SIC, NAICS or related industry classification fields to improve segmentation and routing.

06

Healthcare appending

Add specialty, NPI, practice, facility or related healthcare fields when the source records and project require them.

Data fields

Append the fields that remove friction from the next workflow.

The input file determines what can be matched. A project can be scoped around a single missing field or a broader set of contact and account attributes.

Fill missing fields before territory assignment, segmentation, scoring or account routing.

02

Campaign preparation

Complete the contact or account fields needed before an email, phone, event or direct-mail program.
