Consumer Data Enhancement
Business Email Data Enhancement

With our Email Append Service, you can pick 3 data elements to be
appended to your file at NO CHARGE.


Postal List Hygiene Services
Our List Hygiene services are designed to save you money on your postal
expenses. By identifying records with undeliverable postal addresses,
correcting and updating typographical errors and zip codes, adding
forwarding addresses, and even removing individuals who have passed
away, we can save you from sending wasted pieces through the mail.

Match & Deploy Services
Walter Karl Interactive's Match & Deploy Service will allow you to use
multi-channel marketing strategies by including email promotions to these
targeted prospects.

Our service includes matching your prospect file to our permission-based
and highly responsive database of 75 million records.

Once the data processing is complete, we broadcast your campaign
to the matched prospects. You campaign includes real-time tracking so
you can monitor the results or execute A/B splits for testing.

Even better, because of our individual-level tracking capabilities, you can
send follow-up campaigns based on each users response to the first
mailing (ie, send non-openers a message with more intriguing subject line;
send openers and clickers that didn't respond a stronger offer).

Because of our multi-file capabilities, you can expect to deliver an email
promotion to approximately 20-30% of your direct mail prospects.

These services will not only improve your deliverability in the mail and save
you money by reducing returned mail, but will also help you improve match
rates for your Email Append.
