Give your postcard a useful QR code, then check what happened

Imagine a gutter-cleaning business mailing a spring postcard to two neighborhoods. The card offers an availability check before the next heavy rain. A homeowner who is interested should reach that availability page in one step, whether they scan the QR code or type the printed address.

After the mailing, the business will have several numbers: pieces mailed, QR scans, visits, calls, forms and jobs booked. Those numbers answer different questions. The useful work starts before printing, when the owner decides what each route opens and how each response will be recorded.

The same setup works for a shop offer or a local event invitation.

What should a recipient do after seeing the card?

Choose one main action. For the gutter-cleaning card, “Check spring availability” is clearer than “Learn more.” The QR code should open the availability or quote page directly. If the page begins with a generic homepage menu, the homeowner has to search again.

Put the relevant details on that page: where the service is available, what the offer covers, when it ends if there is an end date, and how to ask for a quote. A form should work on a phone, show a confirmation and send the enquiry to the place the business actually handles it. Test it while signed out. If the destination is a booking service or shop, that service records bookings and purchases; the QR code gets the visitor there.

Write the action beside the QR code on the postcard. “Scan to check spring availability” tells someone what will happen. Keep the same promise at the top of the destination page. If the offer changes after printing, a dynamic QR code can open an updated page, but it cannot change the words already in the homeowner’s hand. Leave a useful explanation when an offer closes.

USPS described a Jo-Ann postcard with a QR code that opened the retailer’s website. Your own card needs a destination that fulfills its printed promise, whether that is an availability page, a product offer or event details.

Give people a readable address too

Some recipients will look at the postcard while using their phone for something else. Others will set it beside a computer. Print a short, readable web address near the QR code so they can reach the same useful page without scanning. Test the address as printed, including every slash and hyphen.

If you want to count the two routes separately, use one address for the QR code and another for the printed text. Both can lead to the same page. A Graklink short link can count clicks on the fallback route; your own website can also provide a short path. Keep the fallback in business control and record who can update it.

Call the resulting number printed-address route activity. A person might share that address in a message, or scan the QR and later type the address. Neither route identifies how the visitor obtained it. One QR code printed on 5,000 identical cards gives a combined count, not a record for 5,000 households.

For a fixed page on your own domain, a free static QR code and a short website address may be enough. Add campaign tags and use your existing site analytics if you need visit context. Static QR codes cannot change the encoded address after printing, but content at that address can change. A stable address alone does not replace basic scan counts or the deeper timing and comparison tools you may need later.

Choose a printer and test the physical proof

Decide how the postcards will be addressed and mailed before choosing a template. A self-prepared Every Door Direct Mail drop, an addressed list handled by a mail house and a small print-and-mail order have different artwork rules and costs. USPS explains its Every Door Direct Mail paths, including retail and bulk entry. Its printer directory helps locate providers for print and mail preparation. USPS also lists Click2Mail as an online print-and-mail option.

Production route	When to consider it	What to confirm before paying
Prepare an eligible Every Door Direct Mail drop yourself	You have staff time to handle the mailing steps and want to choose carrier routes	Current format and quantity rules, printing cost, preparation, postage, drop-off and a final-size proof
Ask a local mail printer or mail house	You need help with format, addressing, preparation or delivery	Minimum order, paper and finish, physical proof, list handling, postage, setup charges and who submits the mail
Use an online print-and-mail service such as Click2Mail	You want one provider to receive artwork and handle production and mailing	Supported postcard size, order minimum, proof type, list or route options, postage class, tax and complete delivered total

Compare like with like: the same finished size, piece count, stock, finish, addressing method and delivery area. A quoted per-card printing rate is not the total mailed cost. Get the final quote for the actual destination and schedule, including proofing, setup, postage and tax. There is no reliable universal delivered price for this comparison. If a provider only supplies a digital proof, decide whether you need a mailed physical sample before the full order.

Use the chosen provider’s current artwork template. Leave required postal and address areas clear. Give the QR code strong contrast and clear space around it, and keep the printed address large enough to read at final size. Our print-proof guide covers common QR design failures in more detail.

Print a proof at actual size and trim it. Scan it in ordinary light with two phones. Have someone who did not make the card type the fallback address. Then follow the destination through the form or checkout and confirm the test response was received. Test again from the production proof if the finish, size or artwork changes. A QR image that works on a monitor has not passed this test.

Label the mailing before it goes out

Give the drop a name that will still make sense months later, such as “North spring postcard, April.” Record the area or list segment, artwork version, offer, quantity actually mailed, handoff date, likely delivery window, cost, QR route, fallback route and destination. Note the reporting time zone. Keep a copy of the approved proof.

Keep a mail-drop response worksheet with one row per mailing, and a proof checklist beside the approved artwork. Download the editable spreadsheet to enter and compare drops. You can also use the fillable PDF on a device or printable PDF for a paper copy. The worksheet has blank fields and an illustrative two-drop example. Use the spreadsheet for long web addresses and notes; a filled PDF can clip long values in its printed view even when they remain saved in the form. Fill it in this order:

Before mailing	At the first review	At the later review
Drop name, area or list segment, offer, proof version, quantity actually mailed, dates, QR route, readable-address route, destination and campaign tags, total print and distribution cost	Reporting period and source of each number; QR scans, fallback clicks, tagged site visits, calls, forms, bookings, orders or redemptions	New activity since the first review, late outcomes, returns or refunds if relevant, and responses that cannot be assigned confidently

Write the attribution rule on the sheet. For example, count a booking as a postcard response only when the customer used the card’s promotion code or an enquiry record names that card. Record every source used for the counts and leave unknown fields blank rather than entering zero. Write down where each number will come from before the cards leave the printer.

Use a separate QR code when you need to compare two distinct drops, offers or areas. Identical cards in one drop can share a QR code. If the spring and autumn cards use the same QR code, a later scan does not reveal which physical card was scanned. Changing the destination or campaign tags can keep the old card useful, but it cannot identify the printed batch by itself. For tag setup, see the QR code UTM guide.

Different routes help comparison, but they do not create a fair experiment by themselves. Two neighborhoods can differ in household mix, delivery timing, competing promotions or weather. Record those conditions before treating a higher count as evidence that one design worked better. The placement comparison guide explains the same issue for QR codes placed in different spots.

Read the response after delivery, then look again later

Start the log with the mail provider’s handoff and any delivery estimate it supplies. Those are mailing facts, separate from whether a particular household received, saw or read the postcard. You can report scans per 1,000 pieces mailed to compare drops of different sizes. Label that figure accurately: mailed pieces are not verified deliveries, people reached or opportunities to scan.

During your chosen review period, add QR scans and fallback-route clicks by date. If the destination site has analytics, add tagged visits there. Then add enquiries and completed outcomes from their actual systems: calls from your phone records, form submissions from the form service, bookings from the scheduler, orders from the shop and redemptions from the register. A dedicated phone number or promotion code can help identify some responses if your business already uses one, but Graklink does not record those outcomes from a QR scan.

Keep an “unassigned” column for responses you cannot connect confidently to the postcard. A caller may have seen an ad as well as the card. A homeowner may scan twice, then call from a different phone. A customer may type the business name into search rather than use either printed route. Do not force those responses into the QR total.

Set the first review date before mailing and a later date for retained cards. For example, check the early response after the likely delivery window, then review again after the offer ends. Record both dates instead of treating the first week as the whole result. A card left on a kitchen counter can generate a late enquiry, and two mail drops can overlap in time. Keep each drop’s route and reporting period visible when reading the trend.

Compare the next print decision with the costs and actual outcomes you can support. If one drop produced more QR scans, check whether it mailed more pieces, ran longer or used a different offer. If one had more booked jobs, verify how those jobs were attributed and whether refunds or cancellations changed the result. For comparing direct mail against email or ads, use the multichannel campaign guide and include each channel’s full cost. Counts alone do not establish that the postcard caused a sale.

Choose the smallest QR setup that answers your question

For a single fixed postcard, start with the page you already control and Graklink’s free static QR code if that gives you what you need. Existing website analytics can measure tagged visits on a properly configured page. Graklink’s static QR code does not provide a managed scan counter.

A Graklink dynamic QR code lets you edit the destination after printing and includes basic scan counts, even when the page never moves. A permanent short link for the readable fallback has its own activity count. Check the full printed address before ordering the cards.

Approximate scan location cannot identify a household or reliably prove which mailing area a person lives in. The booking or order system remains the record of completed business.

Choose the promised page, test one printed card and start the mailing log. The useful answer comes from checking the postcard, the response routes and the business records together.
