How It Works


Email Append Process

Getting Started

We'll need a list of customer names and postal address. We have various match levels depending on your data type. If it's a residential list, we'll at least need their postal address and preferably name. For businesses, company name and postal address is preferred. We can work with most data formats and can discuss questions you might have.

We know your privacy is important, so be assured that your information will always be protected within our secure data center located within our facility.

Clean & Standardize

In order to provide the best match rate possible, nSightful will take your customer database and perform the hygiene and standardization process. We will remove duplicate records and run your data through several postal address hygiene processes including the USPS CASS Certification. This allows for higher match rate and deliverability on the append process.

Match & Append

Superior data quality and multi-sourcing our append and verify process sets us apart from our competitors. Providing both positive and negative identifications to our match logic we are able to identify the right individual with the right email address at either the individual or household level.

Email Confirmation & Engagement

Once we have matched records, the email addresses are verified as deliverable and then sent an engagement message. This message is deployed through the nSightful platform on your behalf to confirm deliverability.

Results from Engagement Campaign

All undeliverable hard-bounce emails are omitted and opt-out responders are flagged in your results file.

Final Standardize & Quality Check

The final results file will be returned to you with the deliverable email addresses attached. We will also provide you with a file of "opt-out" records to be suppressed in your future email marketing programs.
