How utility companies can turn direct mail into powerful marketing tools that enhance customer experience with Utility Bill Inserts
Every month, without fail, your customers open the bill they receive in the mail. Not because they want to — because they have to. That moment of attention is one of the most reliable customer communication opportunities available, yet most utility companies leave it almost entirely unused.
Utility Bills = Guaranteed Open
What does that mean for your company? It means a captive audience reviews everything that gets delivered with your invoice, including utility bill inserts, otherwise known as statement stuffers.
A marketing channel with guaranteed opens is rare—and utility bill inserts deliver exactly that. Riding along with the bill, they put your message directly in front of customers.
The economics are appealing. You’ve paid for the envelope, the bill printing and the postage. Adding an insert adds very little additional cost, essentially the cost of printing and inserting. Add a QR code and you effectively connect your physical and digital marketing into an overall messaging strategy that strengthens customer connections.
Utility Bill Insert Messaging
Buckslip
A buckslip is a single-sided or double-sided slip the size of a dollar bill, typically 3.5” x 8.5.” Single or double-sided, it should carry one main message: a rebate offer, or paperless billing program enrollment. Buckslips are low cost, high visibility statement stuffers (especially when using colored paper stock) and impossible to miss when the envelope is opened.
Postcard Insert
Printed on heavier stock for greater visibility and durability, postcard inserts are highly effective for service announcements, program promotions, maps, and customer education. Common utility insert sizes include 3.5″ x 8.5″ and 4″ x 8.5″, providing greater visual impact than a traditional buckslip while fitting neatly inside standard billing envelopes.
Flyers/Full-Page Inserts
A flyer insert is a letter-size, 8.5” x 11,” that provides more room than a buckslip or postcard. It’s the right format for messages that are more detailed, or any offer that benefits from supporting visuals, or more complex layouts.
Bifold/ Trifold Inserts
Use a bifold or trifold insert when you need to explain, not just announce. A brochure-style statement stuffer gives you room to guide the reader—and is more likely to be kept—while still fitting neatly inside a standard billing envelope.
Coupon Inserts
Coupon inserts typically offer a discount or other promotion that consumers will value. These can be 3.5″ x 8.5″ (buckslip size), printed on a postcard, or designed as a perforated tear off at the bottom of the bill itself.
Mini-Magazine or Newsletter
A newsletter or mini magazine is more than an insert—it can become a 12-month series of stories, infographics, and spotlights. At the most substantial end of the spectrum, a newsletter or four- to eight-page folded mini-magazine can enhance customer engagement.
Reply Card or Survey
A reply card or survey card is a pre-addressed return card that turns the billing envelope from a one-way communication into a two-way conversation. A pre-addressed, printed reply card removes barriers, and a customer can choose when to fill it out and place into the mail.
Envelope Snips (Onserts)
Called an envelope snip, or onsert, places messaging directly on the statement or envelope exterior, making it the first thing customers see. These are highly effective for urgent notices, conservation alerts, outage information, and time-sensitive program promotions.
Customized Letters
Unlike a general statement stuffer delivered to every customer, custom letters allow utilities to target communications only to the customers who need them. Personalized letters can be used for service notifications, payment assistance programs, rate changes, infrastructure projects, regulatory communications, account updates, and other customer-specific information. Variable data printing makes it possible to customize messaging based on customer type, service area, account status, or program eligibility, creating relevant communications.
Water Quality Consumer Confidence Reports (CCR)
For water utilities, Consumer Confidence Reports (CCR) are more than a regulatory requirement—they’re an opportunity to build trust. Statement inserts provide a cost-effective way to distribute water quality information directly to customers. A printed insert can summarize key findings, explain testing results in plain language, and use QR codes to direct customers to the full report online.
