Extra Steps Can Cut Bad Addresses to Lift Mail Response

/in , , , , , , , , , , /by

Bad address data continue to depress ROI for a significant chunk of direct mail marketers. For mailers struggling with bad addresses and deliverability, AccuList® suggests three remedial steps that go beyond standard merge-purge processing and USPS National Change of Address (NCOA) updating.

But first the good news for direct mail fans: The channel’s superior response and ROI lead 58% of marketers to plan expanded investment in direct mail across industries in 2023, according to a recent survey by Lob and Comperemedia. The bad news: 32% of marketers still worry about achieving response goals because of “bad address data.” 

So what can mailers do to cure this “bad address” problem?

#1 Check Individual Record Quality Before Processing

The initial step AccuList recommends is implementation of a data processing and quality control regimen before merge-purge, hygiene updating or appending of new data, whether for prospecting files or house files.  For example, first and last name on internal and external lists should appear in separate fields, along with the corresponding postal address in separate columns.   

At AccuList, our data experts begin by applying utility programs to individual records before standardizing them to find hidden duplicate or misspelled names, titles and addresses, or other deliverability issues. Next, we use the USPS Coding Accuracy Support System (CASS) certification on individual records to verify that each address matches with the right zip code and delivery route. 

#2 Correct for Multiple Deliverability Issues

The second step is to update mail files for multiple potential address and deliverability issues. Mailing files should be:

1) devoid of house file do-not-mail requests;

2) matched against DMAchoice (the Association of National Advertisers—ANA—mail preference service);

3) updated against USPS NCOA to meet Move Update requirements;

4) address-corrected to meet USPS Delivery Point Verification (DPV) standards; and

5) run against other public source databases for records not found with NCOA, such as deceased or prison addresses.

#3 Go Beyond NCOA

Because the USPS FASTforward or NCOALink represent only a portion of total US movers, a third step is to initiate more advanced mover hygiene.  At AccuList, we also access the most comprehensive public and private “Mover” databases commercially available to fill in the gaps. We can then identify a much greater number of postal addresses that are verified as Deliverable or Undeliverable As Addressed (UAA). 

In fact, this advanced hygiene allows us to identify up to twice the number of address changes versus matching addresses on the NCOA database. And we can not only confirm if the intended recipient is no longer at that address but help find the new address by comparing real-time information.

Via these extra data processing steps, marketers can eliminate duplicate names and addresses, avoid offending those who do not want unsolicited mail, reduce undeliverable mail and wasted postage, and earn postal discounts. An important “byproduct” of this process for prospecting mail is the identification of “multi-buyers.” You can mail them a second time, absolutely free, subject to list owner approval of your mail date and creative!

Smart List, Mail Design Choices Help Save on Postage

Direct mail has higher average response rates than digital choices, but maximizing mail ROI requires cost efficiency, especially in the postage realm. Good list selection and hygiene are key to avoiding mailing waste, and this is one area where AccuList USA’s expertise in targeted mailing lists selection and data services can certainly aid clients. Another important factor in controlling postage costs is mail package design. An article by Target Marketing magazine’s Summer Gould offers a great summary of how smart choices in lists and design can add up to savings.

Targeted, Clean Lists Cut Postage Waste

If you are sending mailings to the wrong people, people unlikely to be interested in your offer, lower response rate and cost inefficiency will be reflected in poor ROI. Using tools from predictive modeling to customer profiling to segmentation can improve list choices and targeting parameters. Plus, AccuList USA’s proprietary list research can help clients find the top-performing lists for their specific vertical market. But no matter how data is targeted, dirty data with duplicates, errors, invalid addresses, and old demographic or purchase history information will create costly delivery failures and misdirected waste. That’s why AccuList USA goes beyond list brokerage to provide expert merge-purge services that combine and standardize data in order to eliminate duplicates, identify and correct old or undeliverable addresses, verify zip codes, and maximize postal discounts. In fact, by comparing names and addresses to real-time information on multiple public and private databases, AccuList USA offers an advanced hygiene regimen that is able to identify and correct twice as many addresses as standard USPS FASTforward and NCOALink use, which only represent a portion of U.S. movers and undeliverables.

Careful Design Wins Postage Discounts

USPS offers postage discounts to mail pieces that are not only addressed correctly but also designed for processing on automated equipment. For mail to qualify for the lowest postage rates, the mail piece needs to be at a letter size, which is a minimum of 3 ½” high by 5″ long and a maximum of 6″ high by 10½” long. Larger mail pieces fall into the flat category, which can cost more than twice as much per piece as a letter. Plus, to take advantage of automation, the piece must by rectangular, with an aspect ratio (length divided by height) of 1.3 to 2.5. Mail pieces outside those ratios could cost twice as much in postage. Then the addressing and barcode block on letter size mail must fit into the USPS OCR read area to avoid additional postage. For tri-folded self-mailers, the address must be on the center panel to qualify for discounted automation postage. Naturally, weight matters.  Keep the weight of a folded self-mailer under 1 ounce; if the piece weighs over 3 ounces, it must go in an envelope. Thickness counts, too  If a mail piece is less than 0.009″ thick, it costs more in postage. On the other hand, the  maximum thickness for letter size mail is ¼” and for flat size is ¾”. The best advice is to consult with your mailing service provider about any new design in advance. For more, see https://www.targetmarketingmag.com/post/save-money-postage/
