Email FAQs

Experian Data Quality's service identifies whether or not an email address is valid and deliverable, allowing you to remove harmful email addresses before you mail them.  Experian Data Quality validates every component of an email address, including the syntax, validity of the domain, and existence of the username. The username validation is done via a variety of methods including an SMTP communication, and other proprietary methods designed to provide the most accurate results.

Your Email Service Provider (ESP) has the responsibility of making your mailings as effective as possible. An effective mailing is one that reaches every intended subscriber's inbox and your ESP wants to ensure that your emails will achieve that goal. Many ESPs have their own tool that does an initial scan of your list, in order identify any potential red flags that may affect the performance of your email campaign. Once they've scanned your list, they will recommend you validate it, specifically to identify which emails are invalid and may be harmful to your Inbox Placement Rate and Sender Reputation. When you remove these addresses from your lists, your ESP will be pleased with your deliverability... and so will you!

Address FAQs

Experian Data Quality leverages the most recent data from the United States Postal Service® (USPS®) to verify your list of addresses.  Simply upload your file and Experian Data Quality's service will quickly verify the address data, correcting minor errors and identifying which addresses are good for mailings and which need more attention.

The first row of your file must contain column headings.  Any column that contains address information must include "address" within the header.  You are free to label any other column on the spread as you would like.

Experian Data Quality organizes your results into three buckets so you can quickly segment your data and mail to only deliverable addresses.  Addresses in the "Verified" and "Corrected" categories are confirmed to be deliverable addresses  and can be mailed to.  Addresses in the "Unmatched" category are missing important information such as apartment or suite information, or contain multiple errors that cannot be automatically corrected by an automated service.  These addresses should not be mailed to as they will likely result in returned mail.
