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/

 

Format Drives Differences in Direct Mail Results

In planning direct mail campaigns, marketers often turn to standard industry benchmarks courtesy of the annual “Response Rate Report” from the Data & Marketing Association (DMA), soon to be a division of the Association of National Advertisers (ANA). However, while general direct mail response rates for house lists (5.1%) and for prospect lists (2.9%) far outpace those of digital media, the mailing piece format selected can make a key difference in expected results.

Mailer Format Shifts Response Metrics

For example, an oversized flat envelope package tends to deliver the highest response rate: 6.6 % for a house file and 4.9% for a prospect list. Next most effective in terms of response are postcards, with a house file response rate of 5.7% and and a prospect names’ response of 3.4%. At the tail end, but still far above digital efforts, comes the standard letter format, with a 4.37% response rate for house names and a 2.5% response for prospecting.

Balancing CPM & ROI in Format Selection

Some marketers hesitate over the more expensive oversized flats, which have the highest cost per thousand (CPM) among formats at $481 for house files and $467 for prospect files. Which is why postcards continue to win fans among B2C and B2B marketers, with the lowest CPM among direct mail formats benchmarked. However, despite their higher CPMs, the solid response rates of flats mean they can deliver the highest ROI (37% and 30% for house and prospect names, respectively). Postcards and letter packages, meanwhile, are tied in terms of ROI, with house mailings garnering a 29% ROI and prospecting turning in 23% ROI.
