Consumer  Email Append – How it Works 

1.  We receive your customer data.

All we need to start the process is your list of customer names with their postal addresses. We work with most data formats, and your information will always be protected within our secure system environment. We'll remove duplicate records and apply standard postal address hygiene including CASS.

2. The match is performed.

Your customer file is matched against our database of over 500,000,000 consumer records to retrieve the corresponding email addresses. We consistently find email addresses for 15% - 30% of all records that are submitted to us.

3. A permission request is sent.

We create and send a customized permission request message that will direct your customer to a website with your logo. There, your customer can either opt-out of future email messages from you, update their contact information, or provide an alternate contact.

4. We return your database with email addresses appended.

All undeliverable matches are omitted and opt-out responders are flagged. A final file containing deliverable matches is returned to you.

Business Email Append – How it Works 

1. We receive your customer data.

Your customer file, including company name, will be received and standardized. We'll remove duplicate records and apply standard address hygiene including CASS. We work with most data formats, and your information will always be protected within our secure system environment.

2.The match is performed.

We locate the domain used for email by your contact's company. (e.g. @us.ibm.comfor IBM). The naming convention (e.g. firstname.lastname) for that domain is determined by consulting our database of 90 million unique email addresses. The contact's email address is then derived by following the pattern for the domain.

3. A permission request is sent.

We create and send a customized permission request message that will direct your customer to a web site with your logo. There, your customer can either opt-out of future email messages from you, update their contact information, or provide an alternate contact. If our first derivative of the contact's email address is unsuccessful, we will attempt other possible nicknames (e.g. William to Bill ) or other common naming conventions. If the address remains undeliverable, it is discarded.

4. We return your database with email addresses appended.

All undeliverable matches are omitted, and people who unsubscribed are flagged. A final file containing only deliverable matches is returned to you. The whole process takes about 2 to 6 weeks, depending on the size and complexity of the file.
