By comparing your files to a continually growing database of more than 80 million individuals, EmailFinder is able to find email addresses for 8-20% of your constituents, typically doubling the number of email addresses in an organization's database.

Once matches are identified, we'll send an introductory email to verify addresses and allow individuals the chance to opt out of receiving email communications. This approach tends to yield individuals who have self-selected the electronic medium as a preferred method of communication, resulting in high response rates to future campaigns.

If you will be using a third-party vendor to send emails, such as Constant Contact, please review our suggestions for using EmailFinder results with opt-in vendors prior to submitting your data. See How to submit Data for Data Enrichment Services for database specific instructions.
