USPS Informed Delivery for marketers: free digital impressions on your mail

USPS Informed Delivery gives a physical mailpiece a second appearance, this one on a screen. Enrolled recipients get an email with grayscale scans of the address side of letter-size mail due that day. Through a free interactive campaign, the mailer can put a full-color ride-along image and clickable URL beside that preview.

The word "free" needs a qualifier. USPS doesn't add a campaign fee or postage charge, but you still have to print and mail the piece. Somebody also has to wrangle the image, landing page, barcode data, and submission. What you get is one more branded contact, usually before the recipient has walked to the mailbox.

What USPS Informed Delivery shows recipients

Informed Delivery is a free USPS service for eligible addresses. When mail or packages are coming, a subscriber receives a Daily Digest email. For letter-size pieces, that digest generally includes a grayscale image of the exterior, address side. USPS isn't photographing what's inside.

USPS reports more than 70 million customers using the service. That's enough reach to take seriously, but don't mistake the big subscriber number for coverage of your whole list. Plenty of recipients won't see a preview.

With no interactive campaign attached, the automated grayscale scan may be all the recipient sees. Add a campaign and USPS can show a color ride-along below it, along with a "Learn More" link to the HTTPS page you choose. The ride-along itself is clickable. Letters and postcards may also use a color representative image in place of the scan. Flats require one because USPS doesn't create the same kind of scanned preview for them.

I wouldn't build the campaign as if the email were the main event. The mailpiece still has to work. The digital layer simply lets someone book, register, download, or keep reading without copying a URL off an envelope.

Why USPS Informed Delivery marketing is useful

There aren't many ways to add a digital impression to mail without buying a separate media placement. This is one. A single piece can turn up twice: first in the morning email, then in the physical mail later. The person checking the digest may even be another member of the household, not the name on the envelope.

It isn't free in any useful accounting sense. Creative time costs money. So do campaign setup and the landing page. USPS just doesn't tack on a campaign fee or postage surcharge.

In my experience, the feature earns its keep when the outer envelope deliberately hides the offer. That plain envelope might help a sales letter get opened, yet it has almost nothing to say in a grayscale scan. A color ride-along can carry the next step without forcing a redesign of the physical package. The same rules from this guide to direct mail copywriting still apply: one offer, a concrete reason to act, and one response path nobody has to hunt for.

A digest impression isn't proof that anybody studied the piece. It's an extra contact. No more than that.

How to set up an Informed Delivery campaign

Start while the mail file is still being built. The campaign has to match barcode data printed on the pieces. Once production is finished, you're too late to bolt it on cleanly.

1. Get access. Create a USPS Business Customer Gateway account, then request access to the Informed Delivery Mailer Campaign Portal under Additional Services. The portal is the least complicated route for a small or one-off campaign. High-volume mailers can use PostalOne! electronic documentation or the USPS API.
2. Confirm the barcode data. Ask the operation addressing and printing the job for its Mailer ID and Intelligent Mail barcode serial-number range. Full delivery-point information needs to be in the barcode. Shared Mailer IDs deserve extra attention: define the serial range, or unrelated mail can wind up with your creative.
3. Define the campaign. You'll enter a unique campaign code and title, mailpiece shape, brand display name, start and end dates, Mailer ID, and, when required, a serial range. USPS generally recommends opening the campaign three days before the target in-home date and closing it three days after.
4. Upload the creative. The ride-along image is required. Add a representative image when you want one or the format calls for it. Don't just shrink the print file and cross your fingers; work from the current USPS image checklist.
5. Add and test the URL. It must use HTTPS and connect directly to the mailpiece or its offer. Test the final URL in the portal, redirects and analytics parameters included.
6. Preview and submit. Send the email preview to yourself. Look at it on a phone, where small type and weak contrast become obvious. Check dates, barcode values, image legibility, and the link. Portal campaigns have to be submitted before the USPS cutoff on the day before the start date.

None of this excuses a dirty address file. Informed Delivery can't rescue a bad delivery point, unreadable barcode, or missing suite. Put the list through a proper direct mail address verification process before the final file reaches the printer.

Information to collect from production

Get the Mailer ID, serial-number range, mail-entry date, expected in-home window, and mailpiece shape. You also need confirmation that the barcode contains an 11-digit delivery point. If an outside print operation owns that Mailer ID, ask for permission to use it.

This handoff trips people up. Marketing has the offer and image; production has the identifiers that actually make the image appear. I put both sides on the same launch checklist.

Creative specs for the ride-along image

USPS can change technical requirements. Check the current campaign image document before the final export, even if you've run one of these campaigns before. The established specifications are:

Don't cram a paragraph into the ride-along. At digest size, a logo, a handful of useful words, and a button-like action will beat a tiny advertisement every time. "Book your assessment" works. A generic photo with no action is just decoration.

The promise should stay consistent from the scan to the ride-along, physical piece, and landing page. If you're mailing an event invitation, send the click to the event page, not the corporate homepage. This sounds obvious until launch day. Use the same discipline for QR code tracking on direct mail, but give the ride-along URL its own source value. Otherwise, digital-preview clicks and scans from the printed piece get muddled together.

What campaign results look like

Daily Digest open rates are high because subscribers use the email as a utility. USPS materials and campaign examples commonly show roughly 60% to 70%. That's far above a typical promotional email, and also easy to misread. The number applies to opens of the digest. It doesn't say that 60% to 70% of recipients noticed your piece inside it.

The post-campaign report breaks out the funnel:

Expect click-through volume to be much smaller than open volume. A campaign may still influence an envelope open later that day, a search, a reply, or a sales conversation. That's why I include it in a broader direct mail ROI measurement plan, alongside conversions and pipeline, with a holdout when the volume supports one.

Reserve a destination or source parameter for Informed Delivery alone. USPS reporting shows email and dashboard clicks; web analytics picks up what happened next. Compare the two records. Don't assume every landing-page session came from the printed mailpiece.

B2B caveats and home-office opportunities

Informed Delivery grew up around residential delivery. Some eligible business and PO Box addresses can now enroll, but conventional B2B office mail remains a weak fit compared with consumer mail. Many business addresses aren't enrolled. At companies that do get a digest, it may go to an administrator in the mailroom rather than the executive named on your envelope.

For planning, I treat traditional business addresses as uncovered until the campaign report proves otherwise. Applying the consumer subscriber count to a B2B list will give you a reach forecast you can't defend.

Home offices are the useful exception. Founders, independent professionals, remote executives, consultants, and small-business owners may get business mail at an eligible residence. Your piece can then appear in the same Daily Digest they check for household mail. Be precise here: a confirmed home-office address isn't the same thing as a headquarters, coworking space, virtual office, or commercial mailbox.

One more thing. USPS doesn't hand over a subscriber list or email addresses. You mail the list you already have, USPS performs the eligible-piece match inside its system, and the campaign report returns performance data. Informed Delivery isn't a back door to a prospect's personal email address.

Frequently asked questions

Is USPS Informed Delivery marketing free for mailers?

Yes. USPS doesn't charge an added fee or postage surcharge for an Informed Delivery interactive campaign. Normal printing and postage still apply, as do the costs of creative, barcode preparation, a landing page, and setup time. "Free" describes the USPS digital placement, not the mailing around it.

How do I add a ride-along image to Informed Delivery?

Create the campaign in the USPS Mailer Campaign Portal. Enter the Mailer ID and applicable barcode serial range, then upload a compliant JPEG ride-along and an HTTPS target URL. Preview it and submit before the start date. The image will appear only when USPS can match an eligible processed mailpiece to your campaign data.

What size should an Informed Delivery ride-along image be?

The ride-along can be no larger than 300 pixels wide by 200 pixels high, with at least one dimension reaching that maximum. Save it as an RGB JPEG under 200 KB. Keep the CTA short enough to read on a phone. Recheck the current USPS image requirements before production because specifications can change.

Does Informed Delivery work for business addresses?

It works for some eligible business and PO Box addresses, but don't assume broad office coverage. Enrollment and useful access are much stronger at residential addresses. A corporate digest may be managed by mailroom staff anyway. The strongest B2B case is a confirmed home office where the intended recipient personally gets the Daily Digest.
